Realizing enhanced or novel electronic states in 2-dimensional (2D) materials with atomic thickness, which result from reduced dimensionality and interfacial interactions with the nearby substrate, is of great interest from both fundamental and technological perspectives. Two examples showing we achieve enhanced superconductivity in monolayer FeSe and a tunable band structure in bilayer graphene, respectively, will be presented in the seminar.

Superconducting artificial atoms are created by connecting Josephson junctions, which are nonlinear, non-dissipative elements, to simple electrical circuits. Individual artificial atoms can be coupled using this same toolbox of inductors, capacitors, and Josephson junctions to build novel quantum materials. In this talk, I will discuss prospects for using the fluxonium artificial atom as a building block for topological materials. Topological phases of matter have excitations with exotic quantum statistics and have been proposed as a platform for robust quantum computation.

Abstract

Precision health care is poised to transform what we know about staying healthy, treating diseases and how health care is delivered. The foundation of precision health care is the genomic makeup of each individual. Scientific and technological advances in recent years have made it possible to sequence a human genome in 1-­‐2 days and at a relatively low cost of a few thousands of US dollars.

The nature of superconductivity in SrTiO3 has remained an open question for more than 50 years. The ongoing debate centers heavily on the role that high energy phonons play in pairing, the relevance of multi-band superconductivity, and the nature of superconductivity in the limit of low carrier density. Using a newly developed method for engineering band alignments at epitaxial oxide interfaces, we have explored this problem in Nb-doped SrTiO3 with high-resolution tunneling spectroscopy.

Dr. Simon Groblacher
Mechanical oscillators coupled to light via the radiation pressure force have attracted significant attention over the past years for allowing tests of quantum physics with massive objects and for their potential use in quantum information processing. Recently demonstrated quantum experiments include entanglement and squeezing of both the mechanical and the optical mode. So far these quantum experiments have almost exclusively operated in a regime where the light field oscillates at microwave frequencies.

The successful isolation and manipulation of atomically thin two-dimensional (2D) materials have ushered in a rich new era of fundamental scientific research and technological innovation. Among them, the transition metal dichalcogenide (TMDC) family of the form MX2 (M = Mo, W; X = S, Se, Te) has attracted significant attention as a new class of 2D semiconductors.

PHAS will participate in the UBC "3 Minute Thesis Competition" ( 3MT ) again this year.  The PHAS heat will be on Thursday  March 2,  4-5:30pm - in the colloquium slot.

The Three Minute Thesis (3MT) is an academic competition that assists current graduate students with fostering effective presentation and communication skills. Participants have just three minutes to explain the breadth and significance of their research project to a non-specialist audience.

Clinical magnetic resonance imaging (MRI) has become critical for diagnosis and monitoring of neurological disease. However, conventional MRI is qualitative, limiting our ability to make comparisons between groups and over time. Traditional clinical images are also insensitive to many pathological changes known from histopathological studies to occur in neurological diseases such as multiple sclerosis (MS).

Biological molecules like proteins, DNA, and RNA form a great variety of complex structures that are linked intimately to their biological function. These structures self-assemble in a process known as folding, whereby the linear chain of the molecule changes from a random coil to a specific structure. Folding is a critical process, because if the wrong structure forms then the molecule won't function correctly, leading in many cases to disease.
