Current Research Interests
- Explaining the anomalous line shapes in angle resolved photoemission experiments of High Tc systems using the theory of Extremely Correlated Fermi Liquids.
- Theoretical description of systems with Extreme Correlations (i.e. infinite repulsion models): Theory of the Extremely Correlated Fermi Liquid , A (Non Fermi) Quantum Liquid state .
- Parameter dependent finite dimensional matrices and quantum integrability.
- Theory of the Thermo-power and Thermal transport in correlated materials.
- Superconductivity, Hall effect in Strongly Correlated matter.
- 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.]
- 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.
- Exactly Solvable Model Systems, Quantum Integrability and star triangle relations.
- 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.
- 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.
