Major Goals The major goals of the projects are 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 TMD 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 hold the promise of new technologies. 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. The proposed research investigates new phases and novel phenomena resulting from strong spin orbit coupling in quantum many-body systems. In particular the thrusts are1 Explore new states of matter, such as unconventional superconductivity, obtained due to the unusual spin split bands structure in interacting hole doped transition two-dimensional metal dichalcogenides. Exploit valley selective probes, such as circularly polarized light, to investigate the nature of correlated ground states.
