Current Research Interests
- Physics of Strongly Correlated Matter: Superconductivity, Hall effect, Thermo-power and Thermal transport in Sodium Cobaltate and other triangular lattice systems.
- Statistical mechanics of spin ice and other geometrically frustrated systems with ground state entropy, slow approach to equilibrium.
- 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.
- Theory of Raman scattering for interacting electrons on a lattice.
- Theory of NMR relaxation rates in correlated electronic systems.
- Novel material realizations of frustrated quantum systems in low dimensions e.g. two dimensional Mott Insulating dimer system SrCu2(BO3)2, and their unusual properties. [For a fascinating connection with Archimedian lattices and other topics in 2-d magnetism see preprint by J Richter, J Schulenburg and A Honecker.]
- Mechanisms for superconductivity on lattices from repulsion: Superconductivity from uncertainty principle type squeezed degrees of freedom, Gutzwiller type variational wave functions, RVB and flux phases.
