Ultrafast formation of topological defects in a two-dimensional charge density wave

Y Cheng, A Zong, L Wu, Q Meng, W **a, F Qi, P Zhu… - Nature Physics, 2024‏ - nature.com
Topological defects play a central role in dynamical systems undergoing a non-adiabatic
transition. In solids, topological defects as a result of femtosecond laser excitation have …

Fate of transient order parameter domain walls in ultrafast experiments

L Kong, R Shindou, Z Sun - arxiv preprint arxiv:2407.14250, 2024‏ - arxiv.org
In ultrafast experiments, an optical pump pulse often generates transient domain walls of the
order parameter in materials with spontaneous symmetry breaking, due to either a finite …

Transient ordering in the Gross-Pitaevskii lattice after an energy quench within a nonordered phase

AE Tarkhov, AV Rozhkov, BV Fine - Physical Review B, 2022‏ - APS
We numerically investigate heating-and-cooling quenches taking place entirely in the
nonordered phase of the discrete Gross-Pitaevskii equation on a three-dimensional cubic …
