CM Seminar: Muons for the Quantum Matter

06 Dec2018

Speaker: Kenji M. Kojima Research Scientist, TRIUMF and Affiliated Associate Professor, SBQMI

Time: Dec 6, 2018, 2:00 PM - 3:00 PM

Location: BRIM 311

A S=1/2 polarized particle, which may couple to the near-by electron is the simplest quantum mechanical object, as you may find in the standard text books. In reality, a particle called positive muon (µ+), provides such experimental observations. TRIUMF in the UBC south campus, which is also my home institute since this August, provides muon beams for material science research....

CM Seminar: Moiré is Different: Wigner Solidification at Magic Angles in Doped Twisted bi-layer Graphene

29 Nov2018

Time: Thursday, November 29, 2:00 - 3:00 pm

Location: BRIM 311

Speaker: Prof. Philip W. Phillips from the University of Illinois

In a recent paper, the MIT group led Pablo Jarillo-Herrero has found that doping twisted bi-layer graphene can generate strongly correlated insulating states and superconductivity at particular twist angles called magic angles.

This problem has excited the condensed matter community because it establishes that graphene, normally viewed as...

CM Seminar: Topological cavity states in two-dimensional photonic/phononic chips

22 Nov2018

Speaker: Jian-Hua Jiang, Ph.D., Professor

Time: Nov 22, 2018 14:00 - 15:00

Location: BRIM 311

Abstract: Topological insulators are electronic systems with an insulating bulk and topologically protected boundary states. Conventional 2D topological insulators induce 1D edge states. Recent studies indicate that lower-dimensional topological states are also possible in electronic systems through higher-order topology, which, however, has been confirmed only in Bismuth in experiments [1]. In this talk, I will show that lower-dimensional topological wave...

CM Seminar: Theoretical Description of superconductivity in 2018: a personal assessment

16 Nov2018

Speaker: Frank Marsiglio; Dept. of Physics, University of Alberta

Time: Nov 16, 2018 10:00 - 11:00

Location: BRIM 311

Superconductivity is more than 100 years old, and the established theory of conventional superconductors is more than half as old. But how established is it, and how conventional are the 'old' superconductors? This talk will provide a brief summary of the “state-of-the-art” of superconductivity, and discuss one aspect of pairing that has received some attention lately — “kinetic-energy-induced” pairing. A...

CM Seminar: Linear-, Nonlinear- and Hydrodynamics in Quantum Materials

25 Oct2018

Speaker: Prof. Prineha Narang, from Harvard University

Time: Thursday, October 25, 14:00 - 15:00

Location: BRIM 311

Today, we imagine a world where we can engineer materials and devices atom-by-atom. Exciting discoveries during the past few decades in quantum science and technology have brought us to this next step in the quantum revolution: the ability to fabricate, image and measure materials and their properties at the level of single atoms is almost within our grasp. Yet, at...

CM Seminar: Rare-earth nitrides; semiconductors, spin/orbit magnetism, tunnelling MRAM, superconductivity

18 Oct2018

Speaker: Prof. Joe Trodahl: MacDiarmid Institute for Advanced Materials and Nanotechnology, Victoria University of Wellington

Time: Thurs, Oct. 18, 2:00 - 3:00 pm

Location: BRIM 311

Controlling the flow of electronic spin in addition to the charge promises speed and power demand advantages. However, there are as yet few “spintronic” devices on the market, in part due to a lack of intrinsic ferromagnetic semiconductors that would permit full exploitation of the coupled spin/charge technology. To date the only full series of such materials are the mononitrides...

Seminar: Recent results of REXS and RIXS experiments on quantum materials

01 Oct2018

Speaker: Bernhard Keimer, Max Planck Institute for Solid State Research

Time: Oct 1, 2018 :: 4:00PM - 5:00PM

Location: Brimacombe 311

We will describe how resonant elastic and inelastic x-ray scattering (REXS and RIXS) yield comprehensive, energy- and momentum resolved information about the ground state and excitation spectra of quantum materials. The unprecedented sensitivity of RIXS now allows experiments on dispersive excitations in monolayers and microcrystals of complex quantum materials that were hard to imagine just a few years ago....

Seminar: Road to ultra-low switching Energy Memories to artificial neurons

17 Sep2018

Speaker: Prof. T. Venkatesan, National University of Singapore

Time: Sep 17, 2018 :: 1:30PM - 3:00PM

Location: Brimacombe 311

Memory devices are responsible for a significant fraction of the energy consumed in electronic systems- typically 25% in a laptop and 50% in a server station. Reducing the energy consumption of memories is an important goal. For the evolving field of artificial intelligence the compatible devices must simulate a neuron. We are working on three different approaches towards these problems-...

CM Seminar: Direct Entropy Measurements in Mesoscopic Quantum Systems

06 Sep2018

Speaker: Dr. Nik Hartman

Time: Sept. 6, 14:00 - 15:00

Location: Seminar Room 311 - Brimacombe Building

Abstract : Measuring the entropy of an electronic state is a powerful tool for identifying its underlying microscopic character. Such measurements are typically based on bulk properties that are straightforward to observe in macroscopic samples but exceedingly difficult to access in mesoscopic systems that may consist of just a few electrons or quasiparticles. Taking advantage of a well-known Maxwell...

From solids with topology to black holes and back

06 Sep2018

Speaker: Pr. Marcel Franz from UBC

Time: Thu, 2018-09-13 02:00 - 03:00

Location: Brimacombe 311

Inclusion of topological phenomena in condensed matter physics over the past 10 years ushered a revolution in this field. As a result of the new theoretical insights entire classes of materials with exotic properties have been discovered, including topological insulators, Dirac and Weyl semimetals as well as topological superconductors containing Majorana fermions. In this talk I will give a brief...
