Quantum supremacy: checking a quantum computer with a classical supercomputer

30 Nov2017

Speaker: John Martinis, University of California at Santa Barbara

Time: Thu, 2017-11-30 14:00 - 15:00

Location: Hennings 211

As microelectronics technology nears the end of exponential growth over time, known as Moore’s law, there is a renewed interest in new computing paradigms such as quantum computing. A key step in the roadmap to build a scientifically or commercially useful quantum computer will be to demonstrate its exponentially growing computing power. I will explain how a 7 by...

Complex tensor order and quantum criticality in half-Heusler superconductors

23 Nov2017

Time: Thu, 2017-11-23 14:00 - 15:00

Location: AMPEL 311

A revolutionary new direction in the field of superconductivity emerged recently with the synthesis of superconductors with strong inherent spin-orbit coupling of electrons, such as the half-Heusler compounds YPtBi or LuPdBi. Due to band inversion, the low-energy degrees of freedom are electrons at a three-dimensional quadratic band touching point with an effective spin-3/2, which allows for Cooper pairs with...

Medipix3 hybrid pixel detectors – gaining momentum in the field of electron microscopy

17 Nov2017

Speaker: Dr. Olivia Sleator

Time: Friday, November 17, 2017 at 2:00 pm

Location: AMPEL 311

Detectors have long been a limiting factor in electron microscopy experiments, but we’ve now entered an exciting phase with new detector technology coming into play. In recent years one of the most dramatic advances in structural biology has been in the deployment of backthinned CMOS direct detectors to attain near-atomic resolution molecular structures with electron cryo-microscopy (cryo-EM). Here we...

Frustrated magnetism in metals

16 Nov2017

Speaker: Eundeok Mun, Department of Physics, Simon Fraser University

Time: Thu, 2017-11-16 14:00 - 15:00

Location: AMPEL 311

To date, magnetic frustration has primarily been studied in insulators. There have been little theoretical and experimental studies in magnetically frustrated conducting materials, where the localized moments reside on geometrically frustrated lattices (pyrochlore, kagome, triangular). For the 4f – electron metallic systems, the competition between Kondo and RKKY interactions results in a great variety of ground states, leading to...

Nanoengineering materials: a bottom-up approach towards understanding long outstanding challenges in condensed materials science

10 Nov2017

Speaker: Al-Amin Dhirani, Department of Chemistry and Department of Physics, University of Toronto

Time: Fri, 2017-11-10 15:00 - 16:00

Location: AMPEL 311

This talk will present a variety of examples of such behaviours, such as single electron effects, metal-insulator transitions, semiconductor transistor-like conductance gating, enhanced Andreev reflections at superconducting interfaces and, most recently, strongly correlated electronic behaviour. The latter is particularly exciting since strongly correlated electrons are known to lie at the heart of some of the most exotic, widely studied...

Computational phases of quantum matter

09 Nov2017

Speaker: Robert Raussendorf, SBQMI / PHAS, UBC

Time: Thu, 2017-11-09 14:00 - 15:00

Location: AMPEL 311

In condensed matter physics, the essential properties of a physical system are determined by the phase in which it resides. Recent years have witnessed tremendous progress in the classification of physical phases, and it is thus pertinent to ask: What can we use quantum phases of matter for? Superconductivity is a classic example for a fundamental quantum phenomenon that...

Nanophotonic spin-optomechanics

02 Nov2017

Speaker: Paul Barclay, University of Calgary

Time: Thu, 2017-11-02 14:00 - 15:00

Location: AMPEL 311

Nano-optomechanical devices enhance the interaction between light and nanomechanical resonators, enabling coherent coupling between photons and mesoscopic phonons. When spin systems are attached to or embedded within these devices, technologies for nanoscale sensing, and for transducing quantum information between photons, phonons and spins become viable. In this talk I will illustrate this potential by presenting measurements of the susceptibility...

Non-fermi liquids, fixed point collisions, and tensorial order in grey tin and in some popular field theories

26 Oct2017

Speaker: Igor Herbut, Simon Fraser University

Time: Thu, 2017-10-26 14:00 - 15:00

Location: AMPEL 311

Abrikosov proposed in 1974 that a 3D electronic system with its fermi level at the point of quadratic band crossing, as in the (spin-orbit coupled) gray tin or mercury telluride, should represent the simplest non-fermi liquid. I will review this idea and discuss how a non-fermi liquid ground state may become unstable to ordering via the mechanism of “fixed-point...

Soft, smart multiresponsive materials: Complex matter where simplicity matters

25 Oct2017

Speaker: Debashish Mukherji, Max-Planck Institut für Polymerforschung

Time: Wednesday, October 25th, 2:30 PM

Location: AMPEL 311

Design of multiresponsive smart, soft materials is at the onset of many developments in polymer physics, chemical physics, biophysics and biochemistry research. A system is known as smart responsive when a slight change in external stimuli can drastically alter its structure, function and stability. Because the relevant energy scale in these systems is of the order of thermal energy...

Probing the electronic structure of manganese complexes with X-ray absorption and emission spectroscopy using an X-ray free-electron laser

23 Oct2017

Speaker: Thomas Fransson, Stanford PULSE Institute, SLAC National Accelerator Laboratory

Time: Mon, 2017-10-23 11:00 - 12:00

Location: AMPEL 311

Understanding the structure and dynamics of transition metal complexes has long been one of the grand challenges of inorganic chemistry, with numerous applications in, e.g., the development of energy-efficient catalysts, the investigation of metalloenzymes and improvement of pharmaceuticals, and artificial photosynthesis. In this talk I will present the development and application of X-ray spectroscopy methods for investigating such complexes,...
