Nucleation for one-dimensional long-range Ising models

Aenout C. D. van Enter, Bruno Kimura, Wioletta Ruszel +1

In this note we study metastability phenomena for a class of long-range Ising models in one-dimension. We prove that, under suitable general conditions, the configuration -1 is the…

Critical Dynamical Exponent of the Two-Dimensional Scalar Model with Local Moves

Wei Zhong, Gerard T. Barkema, Debabrata Panja +1

We study the scalar one-component two-dimensional (2D) model by computer simulations, with local Metropolis moves. The equilibrium exponents of this model are well-establishe…

Microscopic Features of Bosonic Quantum Transport and Entropy Production

Mihail Mintchev, Luca Santoni, Paul Sorba

We investigate the microscopic features of bosonic quantum transport in a non-equilibrium steady state, which breaks time reversal invariance spontaneously. The analysis is based o…

Controlling Dynamical Quantum Phase Transitions

D. M. Kennes, D. Schuricht, C. Karrasch

We study the dynamics arising from a double quantum quench where the parameters of a given Hamiltonian are abruptly changed from being in an equilibrium phase A to a different phas…

Deviations from Off-Diagonal Long-Range Order in One-Dimensional Quantum Systems

Andrea Colcelli, Giuseppe Mussardo, Andrea Trombettoni

A quantum system exhibits off-diagonal long-range order (ODLRO) when the largest eigenvalue of the one-body-density matrix scales as , where is the total numb…

Integrable Floquet QFT: Elasticity and factorization under periodic driving

Axel Cortés Cubero

In (1+1)-dimensional quantum field theory, integrability is typically defined as the existence of an infinite number of local charges of different Lorentz spin, which commute with…

Machine learning algorithms based on generalized Gibbs ensembles

Tatjana Puskarov, Axel Cortes Cubero

Machine learning algorithms often take inspiration from established results and knowledge from statistical physics. A prototypical example is the Boltzmann machine algorithm for su…

Generalised Langevin Equation Formulation for Anomalous Diffusion in the Ising Model at the Critical Temperature

Wei Zhong, Debabrata Panja, Gerard T. Barkema +1

We consider the two- (2D) and three-dimensional (3D) Ising model on a square lattice at the critical temperature , under Monte-Carlo spin flip dynamics. The bulk magnetisation…
