Current Research
The TEQM group is part of the Quantum Condensed Matter Theory (QCMT) group in the department of physics at IIT Kanpur. In the TEQM group, we are dedicated to discovering the nature, properties, and possible applications of different quantum materials working in close collaboration with experimentalists.
Currently, we are focused on understanding the interplay between strong electronic correlations, symmetry, and topology in different superconducting quantum materials. These materials have multiple degrees of freedom, such as orbitals, valleys, and sublattices. This interplay is schematically represented above.
To explore the competing orders that arise due to strong electronic correlations and geometric frustration caused by the underlying lattice, we use a combination of model Hamiltonian based approaches, ab-initio method based approaches, and machine learning techniques.
