Lea Nienhaus – Florida State University Title: Stressing Halide Perovskites: Nanoscale Investigation of the Properties of Perovskite Thin Films Abstract: Solution-processed perovskite thin films consist of small grains with a size of 20 - 2000 nm connected by grain boundaries. As a result, there is a vast inhomogeneity in the optical and electronic properties of […]

Marcel Franz – Quantum Matter Institute Title: d-mon: an improved transmon qubit based on a cuprate Josephson junction   Abstract: Transmon qubit, based on a superconducting Josephson junction shunted by a large capacitance, is the workhorse component powering the majority of intermediate scale quantum computers currently in operation. I this talk I will describe a […]

Lindsay LeBlanc – University of Alberta Title: Light-matter interactions in cold and ultracold neutral atomic gases: Applications to quantum memory and holonomic quantum operations Abstract: Neutral atomic gases provide fantastic opportunities for studying and controlling quantum phenomena, ranging from many-body physics to quantum computers. In our research, we use the well-known interactions between cold gases […]

Joe Checkelsky– Massachusetts Institute of Technology Title: Natural Superlattice Design of Modulated Superconductors Abstract: Connecting theoretical models for exotic quantum states to real materials is a key goal in quantum materials synthesis.  Two-dimensional model systems have been proposed to host a wide variety of exotic phases- historically a number of techniques have been used to […]

Xiaodong Xu – University of Washington Title: Observation of Fractional Quantum Anomalous Hall Effect Abstract: The interplay between spontaneous symmetry breaking and topology can result in exotic quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state, which exhibits an integer quantum Hall effect at zero magnetic field due to topologically […]

Jeff Sonier – Simon Fraser University Title: Muon Studies of Superconducting UTe2 Abstract: Recently discovered UTe2 is believed to be a long-sought spin-triplet superconductor, but its magnetic properties and superconducting order parameter are matters of controversy. The observation of a nonzero polar Kerr effect in the superconducting state of UTe2 single crystals exhibiting two phase […]

Nitin Kaushal – Quantum Matter Institute Title: Realization of magnetically frustrated Wigner crystals and a novel multiorbital model in transition metal dichalcogenide based moiré materials Abstract: Moiré materials constructed using the transition metal dichalcogenide (TMD) bilayers have been used to simulate the Hubbard model with long range Coulomb interactions procuring the lattice Wigner crystal states […]

Andrea Young – University of California Santa Barbara Title: Magnetism and superconductivity in rhombohedral graphene multilayers: triplet superconductivity, intervalley coherence, and spin orbit coupling  Abstract: The electronic band structure of rhombohedral graphene multilayers hosts van Hove singularities at which the single particle of states diverges.  I will discuss experiments in which we use electrostatic gates […]

Kaoru Yamanouchi – Institute for Attosecond Laser Facility and Department of Chemistry, University of Tokyo Title: Quantum computing of atomic and molecular problems Abstract: Two-dimensional analogs of metal-halide perovskites represent a promising platform for exciton-polariton-based technologies. They sustain strongly bound excitons that are stable at room temperature, readily enabling strong light-matter coupling at ambient conditions. In the […]

CM Seminar: Carlos Silva-Acuña – Institut Courtois & Département de physique, Université de Montréal Title: Many-Body Exciton Polariton Quantum Dynamics in Optical Microcavities based on two-dimensional Metal-Halide Semiconductors Abstract: Two-dimensional analogs of metal-halide perovskites represent a promising platform for exciton-polariton-based technologies. They sustain strongly bound excitons that are stable at room temperature, readily enabling strong light-matter coupling at […]
