Probing Exotic States of Interacting 2D Electron Systems

There has been a surge of recent interest in the physics of interacting 2D electrons in a large perpendicular magnetic field when they occupy a half-filled Landau level. The long ago proposed composite fermion (CF) picture, in which two magnetic flux quanta are bound to each electron to form a CF, explains many properties of the system. These include the compressible (metallic) behavior of the 2D system at filling factor ν = ½, the existence of a Fermi contour with a well-defined Fermi wave vector, and the presence of fractional quantum Hall states as the filling deviates from ν = ½. In this talk, I will highlight the results of several recent experiments, performed on very high mobility 2D electron and hole systems confined to GaAs/AlGaAs quantum wells, that probe CFs via measuring the geometric resonance of their cyclotron orbit diameter with the period of an imposed, unidirectional density modulation. The data reveal several important aspects: (1) An unexpected asymmetry of the CFs’ Fermi wave vector for filling factors smaller and larger than ν = ½, suggesting a subtle breaking of particle-hole symmetry. (2) Anisotropic Fermi contours for CFs that can be tuned by applying in-plane magnetic field or in-plane strain. The strain results are particularly intriguing as they imply that the CFs inherit a Fermi contour anisotropy from their (parent) zero-field particles through a simple relation. (3) I will also present CF geometric resonance measurements near the even-denominator fractional quantum Hall state at ν = 5/2, providing direct proof for the existence of fully spin polarized CFs. This observation lends crucial credence to the 5/2 fractional quantum Hall effect being a non-Abelian state and therefore of potential use for topological quantum computing.

Hydrodynamics of operator spreading and diffusion in integrable quantum systems

In this talk, I will discuss the recently introduced "generalized hydrodynamics" framework to describe the non-equilibrium dynamics of integrable (and nearly integrable) quantum systems. I will explain how it can be used to capture transport properties, entanglement and operator spreading in such interacting systems. Using simple kinetic theory arguments, I will explain how diffusion can arise from ballistically spreading quasiparticles, and discuss consequences for operator spreading in integrable vs chaotic many-body quantum systems.

Shedding light on the invisible universe

We live in a dark universe, a place where the matter we know, made of electrons, protons and neutrons amounts to just few percent of total energy budget. The remnant electromagnetically silent majority is made by two unknown fluids dubbed Dark Matter and Dark Energy. Understanding their nature is the biggest puzzle in modern physics. I will present our efforts towards numerically model structure (galaxy) formation and evolution in such a dark Universe, and I will show how simulations of galaxy formation are a key tool to test and validate our current Cosmological model. I will also show how a firm understanding of the formation of the visible side of the Universe can be used to put constraints on the nature of its elusive dark components.
