Interaction-stabilized steady states in the driven O(N) model

Year: 2016

Type: article

Abstract: We study periodically driven bosonic scalar field theories in the infinite $N$ limit. It is well known that the free theory can undergo parametric resonance under monochromatic modulation of the mass term and thereby absorb energy indefinitely. Interactions in the infinite $N$ limit terminate this increase for any choice of the UV cutoff and driving frequency. The steady state has nontrivial correlations and is synchronized with the drive. The $O(N)$ model at infinite $N$ provides the first example of a clean interacting quantum system that does not heat to infinite temperature at any drive frequency.
