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...

  • Workshop

CM Seminar: Renormalization group analysis of phase transitions in the two dimensional Majorana-Hubbard model

21 Aug2018

Speaker: Kyle Wamer

Time: Tues, August 21, 2:00 - 3:00 pm

Location: BRIM 311

A lattice of interacting Majorana modes can occur in a superconducting film on a topological insulator in a magnetic field. The phase diagram as a function of interaction strength for the square lattice was analyzed recently using a combination of mean field theory and field theory and was found to include second order phase transitions. One of these corresponds to...

Seminar: Unusual Magnetic Behaviors involving Large Spin-Orbit Coupling

02 Aug2018

Speaker: Jae-Hoon Park, Max Planck POSTECH Center for Complex Phase Materials

Time: Aug 2, 2018 :: 11:00AM - 12:00PM

Location: Brimacombe 311

Large spin-orbit coupling makes the magnetic eigenstate of the total angular momentum state with an admixed spin state and induces unusual magnetic behaviors. In cooperation with the crystal field, it could introduce the Kramers doublet in the magnetic ion site. Then the magnetism is described with the so-called spin-orbit coupled isospin 1/2, and the system often displays novel quantum magnetism...

Seminar: Charge vs. Spin Disorder in a Correlated Electron System

16 Jul2018

Speaker: Janez Bonca, Faculty of Mathematics and Physics University of Ljubljana and J. Stefan Institute

Location: BRIM 311

In the first part [1] I will show that electron-magnon interaction delocalizes the particle in a system with strong charge disorder. The analysis is based on results obtained for a single hole in the one–dimensional t–J model. Unless there exists a mechanism that localizes spin excitations, the charge carrier remains delocalized even for a very strong charge disorder and shows...
