Abstract

Cavalleri and coworkers have discovered evidence of light-induced superconductivity and related phenomena in several different materials. Here, we suggest that some features may be naturally interpreted using a time-dependent Ginzburg–Landau model. In particular, we focus on the lifetime of the transient state in La_1.675Eu_0.2Sr_0.125CuO₄ (LESCO_1/8), which is remarkably long below about 25 K, but exhibits different behavior at higher temperature.
