Superconductivity in the two-dimensional Hubbard model revealed by neural quantum states
Christopher Roth, Ao Chen, Anirvan Sengupta +1
Whether the ground state of the square lattice Hubbard model exhibits superconductivity remains a major open question, central to understanding high temperature cuprate superconduc…
Neural Network-Augmented Pfaffian Wave-functions for Scalable Simulations of Interacting Fermions
Ao Chen, Zhou-Quan Wan, Anirvan Sengupta +2
Developing accurate numerical methods for strongly interacting fermions is crucial for improving our understanding of various quantum many-body phenomena, especially unconventional…
Overscreened multi-channel SU(N) Kondo model : large-N solution and Conformal Field Theory
Olivier Parcollet, Antoine Georges, Gabriel Kotliar +1
The multichannel Kondo model with SU(N) spin symmetry and SU(K) channel symmetry is considered. The impurity spin is chosen to transform as an antisymmetric representation of SU(N)…
Kondo Quartet
Antoine Georges, Anirvan Sengupta
This article describes some recently obtained results on the low-energy properties of the "Kondo quartet" model of two spin-1/2 impurities interacting with two channels (flavours)…
Overscreened Single Channel Kondo Problem
Anirvan M. Sengupta, Yong Baek Kim
We consider the single channel Kondo problem with the Kondo coupling between a spin impurity and conduction electrons with spin . These problems arise as multicritical point…
Non Fermi Liquid Behaviour near a spin-glass transition
Anirvan M. Sengupta, Antoine Georges
In this paper we study the competition between the Kondo effect and RKKY interactions near the zero-temperature quantum critical point of an Ising-like metallic spin-glass. We cons…
On the Emery-Kivelson Solution of the two channel Kondo problem
Anirvan M. Sengupta, Antoine Georges
We consider the two channel Kondo model in the Emery-Kivelson approach, and calculate the total susceptibility enhancement due to the impurity . We find that $χ…
