AUG 2026We provide an explanation of the Mott transition in the 2D extended Hubbard model as a confinement-deconfinement transition of holes and doubly occupied sites.
NOV 2023We 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.
MAY 2023In a work that appeared recently at New Journal of Physics, Patra et al classify various emergent phases of matter in terms of entanglement measures.
MAY 2023In this work, we elucidate the importance of ground-state degeneracy and frustration in determining the physics of the multichannel Kondo model.
FEB 2023We show the emergence of an additional dimension arising out of the scaling of multipartite entanglement upon applying RG transformations on 2D noninteracting electrons placed on a torus.
JUN 2022In this work, we investigate the nature of the general \(N-\)partite information and quantum correlation of a topologically ordered ground state.
MAY 2022In this work, we cast the renormalization group flows of the 2D Hubbard model in terms of entanglement evolution, revealing holographic features along the way.
MAR 2022We analyze the single-channel Kondo model using the recently developed unitary renormalization-group (URG) method and obtain a comprehensive understanding of the Kondo screening cloud.
NOV 2021We present a microscopic derivation of the Cooper-pair insulator (CPI), a topologically ordered counterpart of the $$s-$$wave superconductor.
