Kondo frustration via charge fluctuations: a route to Mott localisation
Abhirup Mukherjee, N. S. Vidhyadhiraja, A. Taraphder +1
We propose a minimal effective impurity model that captures the phenomenology of the Mott-Hubbard metal-insulator transition (MIT) of the half-filled Hubbard model on the Bethe lat…
Holographic entanglement renormalisation for fermionic quantum matter
Abhirup Mukherjee, Siddhartha Patra, Siddhartha Lal
We demonstrate the emergence of a holographic dimension in a system of 2D non-interacting Dirac fermions placed on a torus, by studying the scaling of multipartite entanglement mea…
Unveiling the Kondo cloud: unitary RG study of the Kondo model
Anirban Mukherjee, Abhirup Mukherjee, N. S. Vidhyadhiraja +2
We analyze the single-channel Kondo model using the recently developed unitary renormalization group (URG) method, and obtain a comprehensive understanding of the Kondo screening c…
