CM Seminar - Doping a Mott Insulator and Unconventional Superconductivity in a Triangular Adatom Layer on a Silicon Surface

22 Oct2020

Speaker: Steve Johnston, Professor at University of Tennessee, Knoxville

Time: October 22, 2020 : 2:00PM - 3:00PM

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

Abstract: The physics of doped Mott insulators is at the heart of some of the most exotic physical phenomena in materials research. The adsorption of a one-third monolayer of Sn atoms on a Si(111) surface produces a triangular surface lattice with half-filled dangling bond orbitals. In this talk,...

CM Seminar - The magic of twisted bilayer graphene with spin-orbit coupling

15 Oct2020

Speaker: Alex Thomson - Postdoctoral Fellow at Caltech

Time: October 15, 2020 : 2:00PM - 3:00PM

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

Meeting ID: 657 8412 2083 Passcode: 113399

Abstract: Stacking two graphene layers twisted by the ‘magic angle’ 1.1º generates flat energy bands, which, in turn, catalyzes various correlated phenomena depending on filling and sample details. The importance of the `magic’ angle, however, has recently been challenged by experiments that observe superconductivity in...

CM Seminar - Programming a small superconducting quantum processor with quantum instructions

08 Oct2020

Speaker: Morten Kjaergaard

Time: October 8, 2020 : 2:00PM - 3:00PM

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

Abstract : A quantum algorithm consists of a sequence of operations and measurements applied to a quantum processor. To date, the instructions defining this sequence have been provided by a classical computer and passed via control hardware to the quantum system. I will discuss our recent results...

CM Seminar - The minimal physical picture needed to understand gapping, displacements, mass enhancement, and disproportionation in 3d

01 Oct2020

Speaker: Alex Zunger - University of Colorado

Time: October 1, 2020 : 2:00PM - 3:00PM

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

Abstract: In his seminal work, N. Mott theorized that the insulating behavior of 3 d transition metal oxides emerges This perspective created a general position in the literature that mean-field approaches such as DFT are inappropriate for describing the broad science issues of 3d oxides. The indispensability of the highly correlated approach builds upon illustrations that DFT fails to...

CM seminar : Bad Metals and Electronic Orders – Nematicity from Iron Pnictides to Moiré Systems

24 Sep2020

Speaker: Qimiao Si – Rice University Professor

Time: Sep 24, 2020 :: 2:00PM - 3:00PM

Location: Zoom - link TBA

Abstract: Strongly correlated electron systems typically exhibit bad-metal behavior, which is operationally defined in terms of a resistivity at room temperature that exceeds the Mott-Ioffe-Regel limit. These systems show a rich landscape of electronic orders. Exploring this landscape is an important means to clarify the underlying microscopic physics.

Iron-based superconductors present a striking case study. They are well established...

CM seminar - Orbital-selectivity and nematicity in iron-chalcogenide superconductors

17 Sep2020

Speaker: Ming Yi - Assistant Professor. Rice University

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

Location: Zoom - https://ubc.zoom.us/j/63429511580?pwd=S2lrY29nZ2dBRjZPWGhyeXZQSGx6dz09 Meeting ID: 634 2951 1580 Passcode: 344110

Abstract: Electron correlation effects give rise to a variety of emergent phenomena in quantum materials-high temperature superconductivity, electronic nematicity, Mott insulating phase, and magnetism. In the multi-orbital iron-based superconductors, electronic correlations are manifested in an orbital-dependent way, realizing all of the above in different parameter regimes. In this talk, I will present experimental evidence from angle-resolved photoemission spectroscopy on systematic...

CM seminar - Ferroelectric Superconductors

10 Sep2020

Speaker: Susanne Stemmer - UCSB

Time: Sep 10, 2020 :: 2:00PM - 3:00PM

Location: Please click the link below to join the webinar: https://ubc.zoom.us/j/61875425478?pwd=cDNjWEN1S0lZZ1BTdEpmd3ZZNVdCdz09 Passcode: 113399

Abstract: Polar superconductors have generated significant interest as a potential route to unconventional and topological superconductivity. Strained thin films of doped strontium titanate (SrTiO 3 ) undergo successive ferroelectric and superconducting transitions. Our experimental observations of a factor of two enhancement of the superconducting transition temperature and the fact that both ferroelectricity and superconductivity vanish around the same carrier...

CM seminar : Cavity-mediated spin readout in an industrial silicon transistor

04 Jun2020

Speaker: Joseph Salfi, Assistant Professor at ECE, UBC

Time: May 28, 2020 :: 2:00PM - 3:00PM

Location: Zoom Meeting ID: 918 1320 7475

Abstract: Spin-based quantum bits in silicon are an exciting platform for processing of quantum information. Silicon materials host some of the most coherent quantum two-level systems ever measured [1], and qubits can be manipulated and measured accurately in devices that resemble classical transistors [2]. An often-overlooked aspect of quantum devices is the problem of reading out many qubits on...
