Phase-field method is a density-based computational method at the mesoscale for modeling
and predicting the temporal microstructure and property evolution during materials …

The ultrafast dynamics of electrons and collective modes in systems out of equilibrium is
crucially governed by the energy transfer from electronic degrees of freedom, where the …

The tunability of materials properties by light promises a wealth of future applications in
energy conversion and information technology. Strongly correlated materials such as …

The interaction of many-body systems with intense light pulses may lead to novel emergent
phenomena far from equilibrium. Recent discoveries, such as the optical enhancement of …

Engineering novel states of matter with light is at the forefront of materials research. An
intensely studied direction is to realize broken-symmetry phases that are “hidden” under …

The quench dynamics of a system involving two competing orders is investigated using a
Ginzburg-Landau theory with relaxational dynamics. We consider the scenario where a …

A field theory approach for the nonequilibrium relaxation dynamics in open systems at late
times is developed. In the absence of conservation laws, all excitations are subject to …

Upon excitation by a laser pulse, broken-symmetry phases of a wide variety of solids
demonstrate similar order parameter dynamics characterized by a dramatic slowing down of …

A number of experiments have evidenced signatures of enhanced superconducting
correlations after photoexcitation. Initially, these experiments were interpreted as resulting …

We investigate experimentally both the amplitude and phase channels of the collective
modes in the quasi-1D charge-density-wave (CDW) system, K 0.3 MoO 3, by combining (i) …
