Stellar Kinematics at High Redshift from the LEGA-C Survey and Beyond

Today’s massive elliptical galaxies are primarily red-and-dead, dispersion supported ellipticals. The physical process(es) driving the shutdown or “quenching” of star formation in these galaxies remains one of the least understood aspects of galaxy formation and evolution. Although today’s spiral and elliptical galaxies exhibit a clear bimodality in their structures, kinematics, and stellar populations, it may be that the quenching and structural transformation do no occur simultaneously. In this talk I will present evidence that early quiescent galaxies, observed much closer to their quenching epoch at z~1, retain significant rotational support (~twice as much as local ellipticals). This suggests that the mechanisms responsible for shutting down star formation do not also have to destroy ordered motion in massive galaxies; the increased dispersion support could occur subsequently via hierarchical growth and minor merging. Finally, I will discuss prospects for extending spatially resolved spectroscopic studies of galaxies immediately following quenching with JWST and eventually 30-m class telescopes.

Faster, Smaller, Cheaper: FASER, The Forward Search Experiment at the LHC

For decades the leading attempts to find new fundamental particles have been large undertakings, requiring decades of effort, thousands of physicists, and billions of dollars. More recently, however, new ideas have led to novel opportunities for discovery with relatively fast, small, and cheap experiments. In this talk, I will explain how this new approach came to be and describe FASER, which is under construction now to look for long-lived particles, probe the dark sector of the universe, and detect collider neutrinos for the first time.

Broadband Ferromagnetic Resonance Spectroscopy: The “Swiss Army Knife” for Understanding Spin-Orbit Phenomena

Modern spin-based technologies rely on multiple, simultaneous phenomena that originate from the spin-orbit interaction in magnetic systems. These include damping, magnetic anisotropy, orbital moments, and spin-orbit torques that are manifested in the spin-Hall and Rashba-Edelstein effects. While cavity based ferromagnetic resonance (FMR) spectroscopy has been used to characterize magnetic materials for many decades, recent advances in broadband and phase-sensitive FMR techniques have allowed further refinement, improved accuracy, and new measurement capability. In fact, broadband FMR techniques can now precisely measure spin-orbit torques at the thin-film level without the requirement of device fabrication [1].
Broadband FMR measurements have also improved our fundamental understanding of magnetic damping. Numerous extrinsic relaxation mechanisms can obscure the measurement of the intrinsic damping of a material. This created a challenge to our understanding of damping because experimental data were not always directly comparable to theory. As a result of the improved ability to quantify all of these relaxation mechanisms, many theoretical models have been refined. In fact, this has recently led to both the prediction [2] and discovery [3] of new materials with ultra- low magnetic damping that will be essential for future technologies based on spintronics, magnonics, spin-logic and high-frequency devices.
I will begin this lecture with a basic introduction to spin-orbit phenomena, followed by an overview of modern broadband FMR techniques and analysis methods. I will then discuss some recent successes in applying broadband FMR to improve our ability to control damping in metals and half-metals, quantify spin-orbit torques and spin- diffusion lengths in multilayers, and determine the interrelationships among damping, orbital moments, and magnetic anisotropy [4], [5]. The impact of these result on specific technologies will also be discussed.

2019 Gotham-Metro Condensed Matter Meeting

New York University, Rosenthal Pavilion
Kimmel Center, 60 Washington Square S, New York, NY 10012

New York is a city that never sleeps, and truly, the metropolitan area is constantly abuzz with breakthroughs in condensed matter physics. However, to date there has been little opportunity for physicists at the many institutions in the metro-area to come together to learn and share what is happening in our field. To fill this need, graduate students from the tri-state area have come together to organize the ”Gotham-Metro Condensed Matter Meeting,” and we want YOU to be a part of it. Hosted by the New York University, this is a fantastic chance for students, postdocs and faculty to share ideas and research with fellow physicists training and working in and around the Big Apple. The conference will include keynote lectures by distinguished speakers in both HARD and SOFT condensed matter physics, student talks highlighting current research, and poster sessions presenting research projects from diverse subfields, as well as a catered lunch and reception. With so many avenues for scientific discourse and collaboration, this is an event not to be missed! We kindly ask all participants to register. If you have not already registered, please do so by sending an email to jshabani@nyu.edu with subject line . Registration per institution is $300.
