Dr. Valentino R. Cooper: Exploring the Chemical Landscape of High Entropy Oxides
Virtual eventhttps://ubc.zoom.us/j/68470173961?pwd=RTZEak9Pd01WajVOZHN5SW5YZHcyQT09 Meeting ID: 684 7017 3961 Passcode: 113399 Speaker: Dr. Valentino R. Cooper Title: Exploring the Chemical Landscape of High Entropy Oxides Abstract: High entropy, multi-component metal alloys (HEA), have superior mechanical properties and high radiation tolerances; which are, in part, driven by configurational entropy. Recently, an oxide analogue comprised of MgO, CoO, NiO, CuO […]

High entropy materials are a unique class of systems […]
CM Seminar: Dr. Anushya Chandran – Quantization of Dynamics in Quasi-periodically Driven Systems
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaDr. 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 […]
CM Seminar: Professor Romain Vasseur – Anomalous Diffusion in Quantum Spin Chains
Stewart Blusson Quantum Matter Institute Room 311, 2235 East Mall, Vancouver, British Columbia, CanadaProfessor 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 […]

BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaJoyce Poon - University of Toronto Title: Visible-light Silicon Integrated Photonics for Future Computing Abstract: The emerging demands of computing require hardware advances to realize new types of computing architectures and interfaces. Foundry silicon photonics leverages the maturity of microelectronics manufacturing to fabricate photonic integrated circuits. Today, silicon photonics is mostly used in the short-wave infrared […]
CM Seminar: Professor Kai-Mei C Fu – Quantum Point Defects: Can These Defects Be Less Defective?
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaProfessor 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, […]

BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaLong 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 […]
CM Seminar: Thomas Scaffidi – Spread and Erase – How Electron Hydrodynamics Can Eliminate the Landauer-Sharvin Resistance
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaThomas 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 […]
CM Seminar: Mark Rudner: “The Lindblad Quantum Master Equation: Not Just for quantum Optics Anymore”
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaProf. 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 […]
