CM Seminar - Hidden magnetoelectric multipoles in multiferroics and superconductors

14 Jan2021

Speaker: Nicola Spaldin – Professor, Materials Theory at ETH Zürich

Time: Jan 14, 2021 :: 10:00AM - 11:00AM

Zoom link: https://ubc.zoom.us/j/64183011430?pwd=U2lFNXEwSmlBRWVBdTR5OG1ZdlVSZz09 Meeting ID: 641 8301 1430 Passcode: 113399

Most magnetic materials, phenomena and devices are well described in terms of magnetic dipoles of either spin or orbital origin. There is mounting evidence, however, that higher-than-dipolar order multipoles both exist (often in hiding) and lead to intriguing magnetic behaviors. In this talk I will discuss the...

CM Seminar - Superconductivity in infinite layer nickelates

07 Jan2021

Speaker: Harold Y. Hwang - Stanford University - SLAC National Accelerator Laboratory

Time: Jan 7, 2021 :: 10:00AM - 11:00AM

Since their discovery, superconductivity in cuprates has motivated the search for materials with analogous electronic or atomic structure. We have used soft chemistry approaches to synthesize superconducting infinite layer nickelate thin films from their perovskite precursor phase, using topotactic reactions. We will present the synthesis and transport...

CM Seminar - Twist angle control of moiré superlattice properties

17 Dec2020

Speaker: Elaine Li – University of Texas - Austin

Time: December 17, 2020 : 2:00PM - 3:00PM

https://ubc.zoom.us/j/65784122083?pwd=U09vVXJMRzNLaTY3bmVXNEFJZ1k3UT09 Meeting code: 657 8412 2083 Passcode: 113399

Abstract: In van der Waals bilayers, the strict requirement of lattice matching at the interface is lifted. The periodic changes in atomic alignment lead to the formation of an in-plane superlattice, known as the moiré superlattice. The twist angle controls the size of the moiré supercells and...

CM Seminar - Induced Superconductivity in the Fractional Quantum Hall Edge in Graphene Heterostructures

10 Dec2020

Speaker: Philip Kim – Harvard University

https://ubc.zoom.us/j/65784122083?pwd=U09vVXJMRzNLaTY3bmVXNEFJZ1k3UT09 Meeting code: 657 8412 2083 Passcode: 113399

Abstract: Topological superconductors represent a phase of matter whose properties cannot be smoothly changed from one phase to another, a robustness which renders them suitable for quantum computing. The past decade has witnessed substantial progress towards a qubit based on Majorana modes, non-Abelian excitations whose exchange—braiding—produces...

CM Seminar - measuring current-phase relations in exotic Josephson junctions

19 Nov2020

Speaker: Kathryn Moler, Stanford University

Time: November 19, 2020 : 2:00PM - 3:00PM

https://ubc.zoom.us/j/65784122083?pwd=U09vVXJMRzNLaTY3bmVXNEFJZ1k3UT09 Passcode: 113399

Abstract : Theorists have proposed various exotic Josephson junctions both for fundamental demonstrations of exotic behaviors and as highly desirable platforms for qubits. The supercurrent, I, versus the phase, ϕ, across the junction is called the current-phase relation (CPR) and reveals fundamental properties of the junction. Using a scanning SQUID, we measure...

Abstract: Topological superconductors represent a fundamentally new phase of matter. Similar to topological insulators, the non-trivial topological characteristics of a topological superconductor dictate the presence of a topological edge states composed of Bogoliubov quasiparticles which live inside and span the superconducting gap. The intense interest in these...
