Professor Romain Vasseur – University of Massachusetts, Amherst Title: Anomalous diffusion in quantum spin chains  Abstract: High-temperature quantum transport is usually assumed to be incoherent and diffusive.  In this talk, I will explain how anomalous transport in quantum spin chains can emerge from proximity to special integrable limits, due to a hierarchy of long-lived quasiparticle […]

Professor Kai-Mei C Fu -  University of Washington  Title: Quantum point defects: Can these defects be less defective? Abstract: Point defects in crystals are the solid state analog to trapped ions. Thus these “quantum defects”, which can be integrated into solid-state devices, have gained popularity as qubit candidates for scalable quantum networks. In this talk, […]

Long Ju - MIT Physics Department  Title: Electron Correlation and Coupling with Phonon in the Trilayer Graphene/hBN Moire Superlattice Abstract: ABC-stacked trilayer graphene/hexagonal boron nitride moiré superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. A spectroscopy study of this system is, however, challenging due to the device configuration. In this talk, I will […]

Thomas Scaffidi - University of California Irvine Title: Spread and Erase - How Electron Hydrodynamics Can Eliminate the Landauer-Sharvin Resistance Abstract: What is the ultimate limit of conductance of a metallic device of lateral size W? In the ballistic limit, the answer is the Landauer-Sharvin conductance, which is associated with an abrupt reduction of the […]
