Density of Bloch Waves after a Quench

TL;DR

This paper investigates how the density of Bloch waves produced after a rapid quench decays exponentially with quench time and varies with temperature, revealing minimal textures at low temperatures relative to a characteristic threshold.

Contribution

It provides analytical and numerical insights into the dependence of Bloch wave density on quench time and temperature, highlighting a threshold temperature for texture formation.

Findings

Bloch wave density decays exponentially with quench time

Temperature significantly influences Bloch wave production

Few textures form below a temperature proportional to the magnetic field squared

Abstract

Production of Bloch waves during a rapid quench is studied by analytical and numerical methods. The density of Bloch waves decays exponentially with the quench time. It also strongly depends on temperature. Very few textures are produced for temperatures lower than a characteristic temperature proportional to the square of the magnetic field.
