Michael 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 […]

Étienne 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 […]

Abstract: Many-body correlations drive a variety of important quantum phenomena and quantum machines including superconductivity and magnetism in condensed matter as well as quantum computers. Understanding and controlling quantum many-body correlations is thus one of the central goals of modern science and technology. My research group has recently pioneered a novel pathway towards this goal […]

Abstract: 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 […]

Title:  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 […]

Every 2-3 years, the community of physicists working with ground-based gravitational wave (GW) detectors holds a discussion-based “Dawn” meeting to plan for the future of the field. This year the global ground-based GW community (LIGO, Virgo, KAGRA, Cosmic Explorer, and Einstein Telescope) is coming to us: Blusson QMI is hosting the Dawn VII meeting June […]

In recent years, quantum computing has made continuous progress from improvements in scalability to advancements in error correction codes. This has motivated an increasing focus on exploring use cases and applications. Join us for this year’s second Unboxing Quantum panel, where quantum industry experts and thought leaders will come together to discuss Canada’s rapidly evolving quantum computing landscape. […]

Abstract: 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 […]

Abstract: 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 […]
