Turning the Dials of Quantum Materials via Electron-Lattice Coupling

An essential aspect in the study of correlated materials is the interplay of structural motifs and electronic degrees of freedom. Artificial materials obtained by either heterostructuring or intermixing provide an avenue to not just design new relevant materials, but to obtain insight into the original components themselves. In this talk I will focus on the rare-earth nickelate materials class (RNiO3) using three different examples of artificial materials. Using these, I will explain how different aspects of broken structural symmetry can affect the interplay of correlations, kinetic energy and resulting physical properties.

Collective functionality in intelligent active matter: Bridging multi-scale biology with the physics of solids, fluids and information

Biological systems flourish through collective functionality, by self-assembling into cells, tissues, flocks and parliaments. Understanding this multi-scale organization also lies at the heart of modern engineering and medicine: Pathologies can arise from deficiencies in collective functionality, while active and adaptive materials can be designed from controlling systems out of equilibrium. In this talk, I will overview our recent work on building first-principle theories, numerical tools, and experiments for studying the fascinating physics of life. We will first focus on reliable communication in ultra-fast biology, exemplified by the discovery of ‘hydrodynamic trigger waves’ . Second, we will discuss bacterial contamination dynamics, which is enhanced by the ability of cells to swim against flows. Third, we consider the role of topology in biofunctionality, especially in ‘active carpets’ like ciliary arrays. These insights open up exciting new avenues towards unravelling synthetic and biological active matter, through collective functionality, together.

Learning the Relationship between Galaxy Spectra and their Star Formation Histories using Convolutional Neural Networks and Cosmological Simulations

We study how well deep learning approaches can be used to learn what the underlying SFH of a galaxy is purely from its spectra, using cosmological sims to train and validate the approach. We are also working on extensions to the project that use the outputs of these trained models as priors in SED fitting approaches, leading to more physically constrained posteriors on previously poorly constrained parameters, in particular the SFH.

Single-electron readout and control in a two-dimensional array of quantum dots

The engineering of compact and high-bandwidth readout methods becomes crucial as single qubit are scaled up in one- and two-dimensional arrays to form large scale processors [1]. Recent development of dispersive readout techniques has enabled the demonstration of spin-qubit coherent control in foundry-fabricated devices [2]. In recent years, similar readout techniques have been increasingly harnessed to unveil the non-equilibrium dynamics of varied condensed matter systems, such as SIT transitions [3].
In this talk, I will discuss our recent results on the study of a foundry-fabricated 2x2 array of silicon quantum dots. Two-dimensional arrays constitute a useful platform for spin qubit-processors as well as condensed matter simulations [4]. Exploiting gate-based dispersive readout, we develop a hybrid charge-sensing readout technique that enables us to reconfigure the array as single, double, triple, or quadruple dots. We use dispersive charge sensing to deplete all dots down to the last electron as well as demonstrate the shuttling of individual electrons within the two-dimensional array.

Lessons from the History of Physical Cosmology

LOCATION: Columbia, Davis Auditorium I will review major steps to the establishment of the LambdaCDM cosmology, with particular attention to the many examples of ideas and lines of research that were introduced on more than one occasion, independently apart from our shared culture of physical science. I gather it took a sociologist, Robert Merton, to see that this is a phenomenon that deserves a name: multiples in scientific discovery. I will propose lessons on the nature of our enterprise of natural science to be drawn from the many examples of this phenomenon in cosmology. The talk will be followed by an informal wine & cheese reception in the Physics Theory Center Pupin Physical Laboratories, 8th floor.

Strongly interacting composite fermions: A platform to test the Bloch ferromagnetism and Luttinger theorem

The nature of the ground state of a low-density, two-dimensional electron system has been a topic of intense theoretical and experimental speculation and controversy, because the physics here is governed by strong correlations. Felix Bloch predicted a fully spin-polarized ground state for a dilute fermionic system in 1929. However, such a state has eluded experimental realization for the last nine decades. In the first part of my talk, I will present an experimental realization of the elusive interaction-driven spin polarization in a system of unusual suspects, namely flux-electron composite fermions (CFs). CFs are exotic quasiparticles, each composed of an electron and two flux quanta, formed in the half-filled Landau level of a two-dimensional electron system. As the density of CFs is lowered, the CFs become strongly interacting and make a sudden transition into a ferromagnetic state. In the second part, I will discuss the nature of the CF Fermi sea in the presence of such strong inter-CF interaction. In particular, the applicability of the Luttinger theorem and particle-hole symmetry (time permitting) will be highlighted.

Optomechanics with angular momentum in optical nano-fibers

Nanofibers are interesting optical objects produced by gradually reducing an ordinary single mode optical fiber to half-micron diameters, less than the typical wavelength we use at 780 nm. We have studied the Spin-optomechanical coupling between light and a torsional mode of nanofibers with nanofibers excited with circularly polarized light in the HE11 mode. We have been able to excite these modes also with modes that have orbital angular momentum, but recently we have observed significant changes in thermal noise depending on the angle between the electric field and the apparent birefringence axes of the nanofiber. The result is the reduction/enhancement of noise of the torsional mode with respect to the thermal level depending on the angle.

Simulation of Quantum Many-body Systems

Quantum many-body systems are very hard to simulate, as computational resources (time and memory) typically grow exponentially with system size. However, quantum computers or analog quantum simulators may perform that task in a much more efficient way. In this talk, I will first review some of the methods that have been proposed for this task and then explain the advantages and disadvantages of analog quantum simulators with respect to quantum computers. I will also describe possible applications in condensed matter physics, high-energy physics, and chemistry.

Quantum clocks with ultracold molecules

As quantum science moves beyond controlling atoms, diatomic molecules can be created and optically trapped at ultracold temperatures. This allows exquisite control over the quantum states of the molecules. Using this platform, we can generate long-lived coherent superpositions of far-separated molecular quantum states. The capability to create these superpositions results in a precise clock that is based on molecular vibrations. The vibrational molecular clock allows interatomic force measurements with resolution exceeding a part per trillion, with a potential to improve the constraints on new short-range mass-dependent forces. The full control of the molecular quantum states also helps to shed light on ultracold chemical reactions that proceed as matter waves, and to enable a range of new experiments in fundamental physics and chemistry.

Chemical bonds in square nets and their relation to topology

The very simple structural motif of a square net has gained interest from both, solid-state chemists and condensed-matter physicists, for a long time. The fascinating aspect from the chemistry perspective is the nature of chemical bonding in the motif. If composed if main group elements, in can feature a delocalized, “hypervalent” bond, which violates conventional electron counting schemes. In this talk, I am going to show how this type of bonding can be related to a topological band structure. After establishing this relation, it becomes possible to identify, synthesize and study a variety of new topological semimetals. I will introduce several of these during this talk.

Topological physics in the 2D kagome network

The kagome network, very popular in Japanese art, is one of the possible tilings of two-dimensional space, one with the same point symmetries as the hexagonal lattice of graphene. Recent theoretical developments suggest that the combination of unusual magnetism, spin-orbit coupling, and geometric frustration in kagome metals may lead to a wide range of novel topological physics, such as fractional quantum Hall effect and intrinsic anomalous Hall effect. In these phenomena, a major role is played by the topologically nontrivial flat bands and massive Dirac cones, both of which are predicted to exist from the unique geometrical hopping pathways of kagome lattice. Despite these predictions, the experimental band structure of kagome compounds has long remained unreported.
In this talk, I will report on the experimental band structure of various kagome compounds belonging to the family of transition metal stannides, and in particular Fe3Sn2, FeSn, and CoSn. In these systems which intertwine robust magnetism and electronic topology, we observed various manifestations of topological physics. These include the realization of the Kane-Mele model for 2D Dirac fermions with a spin-orbit-induced topological gap, as well as the discovery of the elusive flat bands with nonzero Chern number.
In sum, transition metal-based kagome lattices have emerged a new platform for intriguing phenomena arising from the combination of topology, magnetism, and correlations. I will discuss the prospects and outlook for further exploration of novel topological physics in this materials family.

Personal Reflections on Two Success Stories

I will share some personal thoughts prompted by two remarkable success stories in physics: i) the standard model of particle physics; ii) the standard model of gravitation and cosmology. In spite of their phenomenological successes both models suggest that the way we are presently dealing with short-distance physics may need some deep revision.

Quantum Engineering of Superconducting Qubits

Superconducting qubits are coherent artificial atoms assembled from electrical circuit elements and microwave optical components1 . Their lithographic scalability, compatibility with microwave control, and operability at nanosecond time scales all converge to make the superconducting qubit a highly attractive candidate for the constituent logical elements of a quantum information processor2,3. In this talk, we review the promise, progress, and challenges of engineering systems of superconducting qubits4. We will also briefly discuss the Center for Quantum Engineering at MIT, its industrial consortium, and their role in training tomorrow’s quantum workforce.

Tensile-strained self-assembly:
Creating new quantum materials by stretching at the nanoscale

Since the early 1990s, self-assembled quantum dots (QDs) have been the subject of intensive research for technologies ranging from high-stability lasers, to intermediate band solar cells. Driven by compressive strain, semiconductor QDs form spontaneously on the (001) surfaces of both III-V and group IV materials. That being said, QDs grown on non-(001) surfaces, and QDs grown under tensile rather than compressive strain, are highly desirable for certain applications. The low fine-structure splitting of (111) QDs should make them ideal entangled photon sources; tensile-strained QDs would have dramatically reduced semiconductor band gaps, with implications for infrared optoelectronics and nanoscale band structure engineering. However, until recently it has been enormously challenging to synthesize non-(001) or tensile-strained QDs that are free from crystallographic defects.
I will introduce a robust new approach to QD self-assembly that overcomes these difficulties, and explain how using molecular beam epitaxy we can reliably and controllably grow defect-free, tensile-strained QDs on (111) and (110) surfaces. I will discuss the application of tensile-strained self-assembly to several different material systems, and present data confirming the promising properties of these novel QDs for entangled photon emission. I will also describe preliminary results in our quest to transform germanium from an indirect to a direct band gap semiconductor by taking advantage of tensile strain at the nanoscale. I believe that tensile- strained self-assembly represents a powerful new tool for heterogeneous materials integration, and nanomaterial development.
