Dr. Anushya Chandran: Boston University Title: Quantization of dynamics in quasi-periodically driven systems Abstract: In the past decade, quantum simulators have increased in their power and scope, offering exquisite dynamical control of tens or even hundreds of individual atoms/ions. Concurrently, a topological revolution in our understanding of electronic band structures has taken place, driven by […]

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 […]

Prof. Mark Rudner - University of Washington Title: “The Lindblad Quantum Master Equation: Not Just for quantum Optics Anymore" Abstract: With the exception of the universe as a whole, the evolution of a quantum system is generically non-unitary due to the coupling between the system and its environment. In quantum optics, the powerful framework of […]

Dr. Alannah Hallas: Blusson Quantum Matter Institute Title: Entropy engineering and tunable magnetic order in the spinel high entropy oxide Abstract: The field of high entropy oxides (HEOs) flips traditional materials science paradigms on their head by seeking to understand what properties arise in the presence of profound configurational disorder. This disorder, which emerges as the […]

Patrick Ledwith – Harvard University Title: Vortexability Chern bands in Twisted and Strained Graphene Abstract: Fractional Chern insulators realize the remarkable physics of the fractional quantum Hall effect (FQHE) in crystalline systems with Chern bands. The lowest Landau level (LLL) is known to host the FQHE, but not all Chern bands are suitable for realizing […]

Dmitri Pikulin – Microsoft Title: Aspects of Microsoft’s recent topological gap study Abstract: I will discuss the theory and data analysis techniques behind the recent study searching for Majorana zero modes. I will describe how the transport techniques can help identify the boundary and bulk signatures of the topological phase. The analytical insight is confirmed […]

John Birkbeck – Department of Condensed Matter Physics, Weizmann Institute of Science. Title: The Quantum Twisting Microscope Abstract: In this talk, I will present a new type of scanning probe microscope, the Quantum Twisting Microscope (QTM), capable of performing local quantum interference measurements at a twistable interface between two quantum materials. Its working principle is […]

Mattias Fitzpatrick – Dartmouth College Title: Quantum Simulation with Superconducting Circuits: Synthetic Quantum Matter to Non-Hermitian Sensing Abstract: In recent years, superconducting circuits have garnered much attention due to their use in quantum computers and quantum annealers. However, this technological platform can also be used to study problems in condensed matter and many-body physics where microwave […]
