Monte Carlo solution of the Kondo model
Nicolas Paris, Oscar Bouverot-Dupuis, Christophe Mora
The Kondo model is a paradigmatic quantum impurity problem realized in a wide variety of experimental platforms and central to the study of strongly correlated electrons. We introd…
Single-worldline theory for a dissipative Mott transition
Oscar Bouverot-Dupuis, Alberto Rosso, Laura Foini
In one dimension at zero temperature, local baths with spectral exponent can stabilize a compressible, non-superfluid dissipative phase between the Mott insulator and Luttinger…
Functional renormalization group study of a dissipative Bose--Hubbard model
Oscar Bouverot-Dupuis, Vincent Grison, Nicolas Paris
We investigate the phase diagram of a one-dimensional dissipative Bose-Hubbard model using the nonperturbative functional renormalization group (FRG). Each lattice site is coupled…
The generic Mott transition in the sine-Gordon model through an embedded worm algorithm
Oscar Bouverot-Dupuis, Laura Foini, Alberto Rosso
The generic Mott transition in one-dimensional quantum systems can be described by the sine-Gordon model with a tilt via bosonization. Because the configuration space of the sine-G…
Bosonized one-dimensional quantum systems through enhanced event-chain Monte Carlo
Oscar Bouverot-Dupuis, Alberto Rosso, Manon Michel
We design an enhanced Event-Chain Monte Carlo algorithm to study 1D quantum dissipative systems, using their bosonized representation. Expressing the bosonized Hamiltonian as a pat…
Random matrix universality in dynamical correlation functions at late times
Oscar Bouverot-Dupuis, Silvia Pappalardi, Jorge Kurchan +2
We study the behavior of two-time correlation functions at late times for finite system sizes considering observables whose (one-point) average value does not depend on energy. In…
Mapping a dissipative quantum spin chain onto a generalized Coulomb gas
Oscar Bouverot-Dupuis
An XXZ spin chain at zero magnetization is subject to spatially correlated baths acting as dissipation. We show that the low-energy excitations of this model are described by a dis…
Antiferromagnetic order enhanced by local dissipation
Oscar Bouverot-Dupuis, Saptarshi Majumdar, Alberto Rosso +1
We study an XXZ spin chain at zero magnetization coupled to a collection of local harmonic baths at zero temperature. We map this system on a (1+1)D effective field theory using bo…
