BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaKamran Kamiri – National Centre for Nuclear Research, Poland Title: Multiscale Modeling of Mechanical Deformation in Chemically Complex Alloys Abstract: In my presentation, I will give an overview of three primary areas that have been my focal research interests at NOMATEN CoE: i) crystal and amorphous plasticity, ii) transport properties of high-entropy alloys (HEAs), and iii) […]
CM Seminar: Janez Bonca – University of Ljubljana: Equilibrium and far-from-equilibrium properties of bipolaron coupled to dispersive phonons
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaCM Seminar: Janez Bonca – University of Ljubljana Title: Equilibrium and far-from-equilibrium properties of bipolaron coupled to dispersive phonons Abstract: In the first part of my talk, I will discuss a Holstein-like model with two electrons nonlinearly coupled to quantum phonons. Using an efficient method based on full quantum approach we simulate the dynamical response of […]
CM Seminar: John Sous – University of California San Diego: Principles for phonon-driven energy solutions in functional electronic materials
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaCM Seminar: John Sous – University of California San Diego Title: Principles for phonon-driven energy solutions in functional electronic materials Abstract: Functional electronic materials are compounds in which correlations amongst electrons and between electrons and ionic vibrations (phonons) give rise to promising new functionalities poised to revolutionize energy conversion, storage and sustainability. In this talk, I will […]
CM Seminar: Fiona Burnell – University of Minnesota: Stabilizing topologically non-trivial steady states with local dynamics in open quantum systems
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaFiona Burnell – University of Minnesota Title: Electrons in twisted layers: design, surprise, and a new set of eyes Abstract: The goal of building a quantum computer has lead to rapid advances in experiments that allow for high-precision dynamical control of quantum systems at the single qubit level. However, a major challenge in harnessing the power […]
CM Seminar: Domenico Giuliano – Department of Physics, Università della Calabria, Italy: Dissipation driven dynamical topological phase transitions in two-dimensional superconductors
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaDomenico Giuliano – Department of Physics, Università della Calabria, Italy Title: Dissipation driven dynamical topological phase transitions in two-dimensional superconductors Abstract: By quenching the interaction strength, we induce and study a topological dynamical phase transition between superconducting phases of a planar fermionic model. Using the Lindblad Master Equation approach to account for the interactions of Bogoliubov […]
CM Seminar: Michael Zaletel – University of California Berkley: Anomalous Hall Crystals in Graphene: interaction-driven Chern bands at zero magnetic field
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaMichael Zaletel – University of California Berkley Title: Anomalous Hall Crystals in Graphene: interaction-driven Chern bands at zero magnetic field Abstract: Recent experiments have discovered that pentalayer-graphene subject to a moire superlattice spontaneously breaks time-reversal, resulting in a quantized anomalous Hall effect at zero magnetic field. At fractional filling, the material exhibits a zero-field fractional quantum […]
Special CM Seminar: Étienne Lantagne-Hurtubise – Caltech: Graphene multilayers: from unconventional superconductors to quantum devices
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaÉtienne Lantagne-Hurtubise – Caltech Title: Graphene multilayers: from unconventional superconductors to quantum devices Abstract: Crystalline graphene multilayers present a rich playground to explore correlated electronic phenomena in a tunable and ultra-clean setting. For instance, Bernal bilayer graphene and rhombohedral trilayer graphene host multiple symmetry-broken metallic phases at low temperature, as well as unconventional superconductors with different […]
Special Seminar: Owen Sheekey – UCSB: Inter-valley coherence, intrinsic and extrinsic spin-orbit coupling in rhombohedral graphene
McLeod 3038 2356 Main Mall, Vancouver, British Columbia, CanadaAbstract: Rhombohedral graphene multilayers provide a clean and highly reproducible platform to explore the emergence of superconductivity and magnetism in a strongly interacting electron system. The high density of states near the van Hove singularities lead to a variety of broken symmetry phases – including exotic forms of spin and valley ferromagnetism . Because of their […]
Special Seminar: Rachel Wortis – Trent University: Many-body localization in the disordered Fermi-Hubbard model
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaTitle: Many-body localization in the disordered Fermi-Hubbard model Abstract: How isolated quantum systems reach thermal equilibrium is a long-standing question of continuing interest. The absence of equilibration in some systems is also well known, notably Anderson localization in noninteracting systems with quenched disorder. However, it has only relatively recently been understood that the absence of […]
Special Seminar: Solids with random stacking: the curious case of lithium
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaAbstract: Close-packing of spheres is a problem with a long, beautiful history that spans centuries. To achieve maximal density, we must first arrange spheres into triangular layers and stack them. Each layer can sit in two possible positions. I will describe the solid that arises from random stacking, i.e., when each twofold choice is made at […]
Special Seminar: Wolf Widdra – Institute of Physics, Martin-Luther-Universität Halle-Wittenberg: Laser-based double photoemission spectroscopy at surfaces
Abstract: With the recent progress in high-order harmonic generation (HHG) using femtosecond lasers, laboratory photoelectron spectroscopy with an ultrafast, widely tunable vacuum-ultraviolet light source has become available. Whereas HHG-based photoemission experiments at kilohertz repetition rates have been severely limited by the space-charge effects in the past, the new development of compact HHG light sources with […]
Special Seminar: David Abergel – Chief Editor of Nature Physics: Inside Nature Physics
BRIM 311 2355 East Mall, Vancouver, British Columbia, CanadaAbstract: What happens to your paper after you submit it to a journal is not always clear from the outside, but it’s helpful for authors to understand the editorial process so that they can navigate it smoothly. In this talk, we will unpack this process and explain how editors make their decisions. We will introduce Nature […]
