Emergence of Nonequilibrium Latent Cycles in Unsupervised Generative Modeling
Marco Baiesi, Alberto Rosso
We show that nonequilibrium dynamics can play a constructive role in unsupervised machine learning by inducing the spontaneous emergence of latent-state cycles. We introduce a mode…
Dissipation splits the Mott transition in one dimension
Oscar Bouverot-Dupuis, Alberto Rosso, Laura Foini
Understanding how dissipation modifies quantum phase transitions is a central challenge in many-body physics. A paradigmatic example is the one-dimensional Mott transition, which i…
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…
