Speaker: Sacha Kocsis, Xanadu Time: 10:00-11:00am Location: BRIM 311 Title: Optical quantum computing with GKP states Topic: Xanadu is a quantum computing company founded in Toronto in 2016 with the goal of building fault-tolerant quantum computers. I will give an overview of Xanadu's recent hardware milestones, and an introduction to Xanadu's strategy for fault-tolerant quantum computing […]

Speaker: Anthony Ayari, CNRS Time: 10:00-11:00am Location: BRIM 311 Title: Field emission as a tool for material characterization in the tunneling regime  Abstract: Vacuum electron sources have a long history dating back to the end of the nineteenth century, and have been at the root for many revolutionary developments, such as the advent of telecommunications and […]

Speaker: Open Quantum System Theory, Kyle Monkman, UBC Time: 10:00-11:00am Location: BRIM 311 Abstract: Non-unitary operations have tremendous potential for use in quantum technology. On the one hand, they can be used to describe the imperfections of experiments which are not fully isolated from the environment. They also describe operations which are necessary for quantum information […]

Speaker: Meigan Aronson, UBC Time: 10:00-11:00am Location: BRIM 311 Abstract: Strong correlations between conduction electrons and magnetic moments reflect the competition between moment instabilities and magnetic order. Investigations of the resulting collective phases and complex phase diagrams in 3D compounds continue to reveal new behaviors, although similar efforts on 1D systems remain very limited due to […]

Speaker: Heike Pfau, Penn State University Time: 10:00-11:00am Location: BRIM 311 Abstract: Understanding how renormalized quasiparticles emerge in strongly correlated electron materials provides a challenge for both experiment and theory. It has been predicted that distinctive spin and orbital screening mechanisms drive this process in multiorbital materials with strong Coulomb and Hund’s interactions. In this talk […]

Speaker: Dr. Serena Eley, the University of Washington Time: 10:00-11:00am Location: BRIM 311 Abstract: In superconductors, the motion of vortices introduces unwanted dissipation that is disruptive to applications, for example, limiting the current-carrying capacity in wires and causing energy losses in microwave circuits.  Fortunately, material defects can immobilize vortices, acting as vortex pinning centers, which engenders […]

Speaker: Dr. Susanne Stemmer, Materials Department, University of California, Santa Barbara Time: Location: BRIM 311 Abstract: Bulk cadmium arsenide (Cd3As2) hosts topologically non-trivial bands in its electronic structure.  In thin films, it can be engineered to a variety of new topological phases.  In this talk, we will discuss topological and correlated insulator states in high-quality quantum […]

Speaker: Ashutosh Singh, UBC Time: 10:00-11:00am Location: BRIM 311 Abstract: I will begin with a pedagogical overview of the recently identified magnetic class known as altermagnets, placing them in context alongside conventional ferromagnets and antiferromagnets. I will then present my research on investigating chiral magnons in the metallic altermagnet CrSb. This will include a discussion of […]

Speaker: Joseph Maciejko, University of Alberta Time: 10:00-11:00am Location: BRIM 311 Title: Topological Landau Theory Abstract: I will discuss a notion of topology “hidden” in Landau’s theory of phase transitions. When the order parameter comprises several components in the same irreducible representation of symmetry, it can possess a nontrivial topology and acquire a Berry phase under […]

Speaker: Janez Bonča, University of Ljubljana Time: 10:00-11:00am Location: BRIM 311 Title: Signature of preformed pairs in angle-resolved two-electron coincidence photoemission Abstract: We employ density matrix renormalization group (DMRG) and variational exact diagonalization (VED) to compute single- and two-electron removal spectra of the Hubbard–Holstein model at low electron densities. By tuning electron–phonon coupling and Hubbard repulsion, […]

Speaker: Ismail El Baggari, UBC Time: 10:00-11:00am Location: BRIM 311 Title: Scanning transmission electron microscopy (STEM) now routinely resolves the atomic structure and chemistry of materials with sub-angstrom resolution. Recent advances in instrumentation further allow spatially resolved mapping of subtle, picometer-scale atomic shifts that underpin emergent functional properties. In ferroelectrics, for example, polarization arises from tiny […]
