Fermionic criticality is shaped by Fermi surface topology: a case study of the Tomonaga-Luttinger liquid
Anirban Mukherjee, Siddhartha Patra, Siddhartha Lal
We perform a unitary renormalization group (URG) study of the 1D fermionic Hubbard model. The formalism generates a family of effective Hamiltonians and many-body eigenstates arran…
Holographic unitary renormalization group for correlated electrons -- II: insights on fermionic criticality
Anirban Mukherjee, Siddhartha Lal
Capturing the interplay between electronic correlations and many-particle entanglement requires a unified framework for Hamiltonian and eigenbasis renormalization. In this work, we…
Holographic unitary renormalization group for correlated electrons -- I: a tensor network approach
Anirban Mukherjee, Siddhartha Lal
We present a unified framework for the renormalisation of the Hamiltonian and eigenbasis of a system of correlated electrons, unveiling thereby the interplay between electronic cor…
Holographic entanglement renormalisation of topological order in a quantum liquid
Anirban Mukherjee, Siddhartha Lal
We introduce a novel momentum space entanglement renormalization group (MERG) scheme for the topologically ordered (T.O.) ground state of the 2D Hubbard model on a square lattice (…
