Quantum Chaos: Universalities in energy level spectral correlations of mesoscopic systems.
Quantum Integrability through star triangle relations and Exactly Solvable Model Systems.
1-d Hubbard model, its conservation laws, the 1/r² Model of interacting spins and s=1/2 quantum spin models in 2-d with simple ground states, studies of excitation spectra. Transport in integrable systems: driven steady states, Kohn type stiffness and twisted boundary conditions.
