Online Colloquium: Topological phases in the real world

ABSTRACT

Topological phases are exotic quantum matters that have non-trivial topological nature in their electronic properties, which often result in robust quantization in bulk transports and excitations localized on the boundary.  In low-dimensional topological superconductors, the boundary excitations are dubbed “Majorana modes” for being their own antiparticles and have been a promising candidate for qubits in quantum computation. Yet, materials hosting topological superconductivity are rare to date. I will discuss examples of how to design and search for material candidates for various types of topological superconductors by exploiting the interplay between topology and symmetry.
 

BIOGRAPHY

Dr. Yi-Ting Hsu is an assistant professor at the University of Notre Dame. She earned her bachelor’s degree in Physics from National Tsing-Hua University in Taiwan in 2009 and obtained her Ph.D. in Theoretical Condensed Matter Physics from Cornell University in 2017. She did her postdoc in Condensed Matter Theory Center, University of Maryland from 2017 to 2020, and then assumed her current position in 2020. She has a broad research interest in condensed matter theory, including topological phases of matter, unconventional superconductivity, correlated phases in van der Waals materials, dynamical phases in isolated quantum systems, and machine-learning application to condensed matter problems.
