第3回 物理工学科教室談話会（講師：Prof. Kenneth S. Burch）

|題目：||Searching for New Excitations in Topological Places|
In this talk I will outline some of the exciting prospects offered by breaking topology along with or in opposition to symmetry. I will focus on two of my groups efforts in this direction, where one may observe majorana Fermions, particles that are their own anti-particle.
The first case involves coupling a high temperature superconductor to a topological insulator, which lead to the observation of an entirely new excitation that only couples to spin and not orbital
In the second case I will discuss our raman experiments on a potential Kiteav Quantum Spin Liquid, that shows a continuum of scattering characteristic of the emergence of new quasi-particles.
