Dynamic scaling behavior in the presence of a periodic magnetic driving across Ising continuous transitions
Andrea Pelissetto, Ettore Vicari
We study the critical dynamics arising from a time-dependent periodic homogenous source coupled to the order-parameter field, which drives a classical ferromagnetic system across a…
Conjecture on the lower bound of the length-scale critical exponent at continuous phase transitions
Andrea Pelissetto, Ettore Vicari
A fundamental issue in the renormalization-group (RG) theory of critical phenomena concerns the allowed values of critical exponents that are consistent with the continuous nature…
Spinodal-like scaling behavior after a temperature quench across the first-order phase transition in three-dimensional -state Potts models
Andrea Pelissetto, Davide Rossini, Ettore Vicari
We study the out-of-equilibrium spinodal-like behavior of three-dimensional (3D) -state Potts models (for ), observed when the temperature is quenched across the first-o…
Coherent and dissipative dynamics at quantum phase transitions
Davide Rossini, Ettore Vicari
The many-body physics at quantum phase transitions shows a subtle interplay between quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we firs…
Out-of-equilibrium percolation transitions at finite critical times after quenches across magnetic first-order transitions
Andrea Pelissetto, Davide Rossini, Ettore Vicari
We show that an out-of-equilibrium percolation transition occurs after quenching ferromagnetic Ising-like systems across their magnetic first-order transitions. As a paradigmatic e…
Quantum quenches across continuous and first-order quantum transitions in one-dimensional quantum Ising models
Andrea Pelissetto, Davide Rossini, Ettore Vicari
We investigate the quantum dynamics generated by quantum quenches (QQs) of the Hamiltonian parameters in many-body systems, focusing on protocols that cross first-order and continu…
