Research Interests

I am predominantly interested in the physics of strong correlation. I deal with the Hubbard model and it’s simple extensions like ionic Hubbard model where as a result of competing insulating tendencies, exotic phases like unconventional superconducting phases emerge. I have expertise in developing formalism for treating strong correlations in presence of inhomogeneities. I have worked with mass imbalanced models where magnetically ordered exotic rare phases like ferrimagnetic metal, spin imbalanced ferromagnetic metal emerge. Presently, I am interested in the physics of constrained models (similar to PXP model) in two dimensions which show strong Hilbert space fragmentation. I am also interested in the physics of superconducting hybrid structures.
