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…
Quenched properties of the Spectral Form Factor
Dimitrios Charamis, Manas Kulkarni, Jorge Kurchan +1
The Spectral Form Factor (SFF) is defined as the modulus squared of the partition function in complex temperature for hermitian matrices and a suitable generalisation has been give…
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…
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…
