Visualizing phase transitions in Weyl semimetal materials
September 17, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Visualizing phase transitions in Weyl semimetal materials

Speaker: Inna M Vishik (University of California, Davis)Host: Ar. Abanov

Weyl semimetals are characterized by pairs of bulk Weyl nodes of opposite chirality, whose surface projections are connected by Fermi arcs. Many of these materials exhibit a high degree of tunability, which opens the possibility for driving topological phase transitions through various modalities. I will present our angle-resolved photoemission spectroscopy [...]
Control of Spin Waves by Spatially-Modulated Strain
September 24, 2021 4:00 pm – 5:00 pm (CDT) ZOOM link
Control of Spin Waves by Spatially-Modulated Strain

Speaker: Ankang Liu (TAMU)Host: A. Finkelstein

We suggest to use spatially-modulated strain for control of a spin-wave propagating inside a bulk magnet. The modulation with the wave vector q=2k mixes spin waves with wave vectors near k and -k. This leads to lifting the degeneracy of the symmetric and antisymmetric eigenstate combinations of these waves. The [...]
Millikan, Geim, Ashkin and COVID-19 aerosol
October 1, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Millikan, Geim, Ashkin and COVID-19 aerosol

Speaker: Igor F. Lyuksyutov (TAMU)

We have modified Millikan and Geim experimental set-ups to trap and manipulate droplets that are the size of COVID-19 aerosol droplets, in a way similar to Ashkin optical tweezers. We plan to have a live demonstration of this experiment which will be done by two undergraduate students, Steven Szaal and [...]

Localization and delocalization in kicked quantum matter
October 15, 2021 4:00 pm (CDT) MPHY 213
Localization and delocalization in kicked quantum matter

Speaker: David Weld (UCSB)Host: Ar. Abanov

A sizable fraction of the vast field of condensed matter physics consists of the exploration of the effects of spatial periodicity on quantum mechanics.  It is now widely recognized that the effects of temporal periodicity give rise to a related array of phenomena, and that the interplay of temporal and spatial periodicity with many-body [...]
Integrability and chaos of 1+1d chiral edge states.
October 22, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Integrability and chaos of 1+1d chiral edge states.

Speaker: Biao Lian (Princeton)Host: Ar. Abanov

I will talk about the integrability and chaos of 1+1d interacting chiral edge states, which may arise on the edge of 2+1d topological phases. We show that integrable chiral Luttinger liquid is not always a good low energy description of the edge states, and marginal interactions can significantly affect their spectrum and integrability. We [...]
Detecting quantum chaos through eigenstate deformations
October 29, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Detecting quantum chaos through eigenstate deformations

Speaker: Anatoli Polkovnikov (Boston University)Host: Ar. Abanov

In this talk I will show how quantum geometric tensor or fidelity susceptibility can be used as a sensitive probe of quantum chaos. In particular, I will show that using this probe one can detect very small integrability breaking perturbations. I will also discuss that ergodic and integrable regimes are [...]
Quantum many-body dynamics of Brownian models
November 5, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Quantum many-body dynamics of Brownian models

Speaker: Shenglong Xu (TAMU)

Recent exciting experiments start to explore long-time quantum dynamics of a closed many-body system. Theoretical understanding of the dynamics is challenging due to fast entanglement generation and often relies on semi-classical approaches. In this talk, I will discuss a class of stochastic quantum many-body models called the Brownian model that [...]
Direct Observation of Antiferromagnetic Parity Violation in the Electronic Structure of Mn2Au
November 12, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Direct Observation of Antiferromagnetic Parity Violation in the Electronic Structure of Mn2Au

Speaker: Jairo Sinova (Johannes Gutenberg Universität)

Research on antiferromagnets with special symmetries is the most rapidly developing field in magnetism and antiferromagnetic spintronics is one of the most exciting developments in condensed matter physics. The PT symmetric antiferromagnets comprise a large part of all possible systems but entail unique features, such as the current induced switching [...]
Topological physics and strong correlations in the 2D kagome network
November 19, 2021 4:00 pm – 5:00 pm (CDT) MPHY 213
Topological physics and strong correlations in the 2D kagome network

Speaker: Riccardo Comin (MIT)Host: Ar. Abanov

The kagome network is a tiling of two-dimensional space comprised of corner-sharing triangles, and one with the same point symmetries as the hexagonal lattice of graphene. Recent theoretical developments suggest that the combination of magnetism, spin-orbit coupling, and geometric frustration in kagome metals is a promising platform to realize phenomena [...]
