Self-introduction
My research interests include understanding the physics of wide classes of materials such as perovskite oxides, strongly correlated materials, Kondo physics, topological insulators, topological nodal-line semimetals, Weyl semimetals, and Dirac semimetals, using angle-resolved photoemission spectroscopy (ARPES) technique. The physical properties of a material are dependent on the electronic structure, which is described by the energy, momentum, and spin of an electron. The significant increase in the photon flux and the advancement in the energy resolution of the electron detector have extended the use of ARPES from a traditional band mapping technique to a precise probe for studying the physics of many-body interactions and dynamics of quasi-particles in complex materials. Tunable photon polarizations (linear and circular) help to identify the orbital character of the energy bands by taking advantage of the matrix element effects. Not only do I find their rich physics alluring, but I am also drawn to the huge potential that these materials carry for future applications. My research interests also includes the use of time-resolved angle-resolved spectroscopy (tr-ARPES) to understand the non-equilibrium relaxation dynamics of topological materials. With an expanding list of topological materials predicted from various theoretical calculations and the continuous development of the technique, ARPES guarantees to be a rich field of study in the coming years.
