We provide a Hamiltonian-based explanation of the DMFT-based phenomenology of the infinite dimensional Hubbard model, obtaining novel insights on the Mott MIT in the process.

Can entanglement scaling lead to universality across various metals and insulators?

In this work that got accepted recently at New Journal of Physics, Siddhartha et al classify various emergent phases of matter in terms of entanglement measures.

Our work on the multichannel Kondo problem has been accepted at J. Phys. Cond. Mat. Check the link for more details.

In this work, we elucidate the importance of ground-state degeneracy and frustration in determining the physics of the multichannel Kondo model.

This work provides an ab initio demonstration of the holographic principle in a prototypical condensed matter system, and sheds new light on geometrical and topological aspects of entanglement in metals.

Welcome to the page of EPQM, a theoretical condensed matter group at IISER Kolkata, led by Siddhartha Lal. EPQM is an acronym for Emergent Phenomena in Quantum Matter. We explore ideas of topological order, entanglement and fermionic criticality (to mention a few), in the field of strongly correlated electrons.
