New states of matter and novel phenomena in spin-orbit coupled systems
Abstract
The goal of the research is to discover and design new states of matter arising from the strong spin orbit coupling in quantum many-body systems. Specifically we explore the new correlated phases and novel phenomena in two dimensional transition metal dichalcogenides and three dimensional Weyl semimetals. Both are characterized by multiple valleys in the energy landscape, with spin split bands possessing nontrivial topological properties. They are representative of a class of materials which are subjects of growing experimental efforts. The challenges are threefold: 1) identify and characterize the thermodynamic and transport properties that can be precisely controlled and widely varied; 2) determine the nature of superconducting phases supported; and 3) find materials that exhibit the novel behavior. Our work address these questions using an array of techniques, which include field theory, symmetry considerations, renormalization group and numerical computation as needed. These efforts contribute to the programmatic goal of furthering the understanding in a field that enables fundamental Army technologies.
