This work reviews the experimental studies on photo-induced cooperative phenomena (photo-induced phase transitions, PIPT), which are related to ultrafast structural and electronic-state dynamics. The review includes a brief history of this research f

Recent experiments indicate that a photostimulated graphite with a femtosecond laser pulse results in the formation of a stable domain with sp 3 like interlayer bonds. By means of the energy barrier minimization and molecular dynamics using the empir

We discuss the neutral-to-ionic phase transition and emergence of the multi-criticality in the quasi-one-dimensional charge-transfer salt TTF-CA under pressure. We stress that subtle interplay of Coulomb and lattice processes may be quite sensitive t

Laser-driven solid–solid phase transition is a new kind of manipulation of matter by light which offers fascinating possibilities for controlling macroscopic switching of materials at different time scales from hours down to femtosecond. Slow dynam

We study energetics of a cooperative low-spin (L) to high-spin (H) transformation in a crystal with two sublattices, where thermo- and photo-induced symmetry-broken phases have been recently observed. The model takes into account an intra-dimer antif

Mixed-stack charge-transfer (CT) complexes undergoing the neutral-ionic (N-I) phase transition are molecular materials formed of stacks where electron donor (D) and acceptor (A) molecules regularly alternate. In the N phase, the CT is low and molecul

We report on high correlation and ordering of multi-electron transfer at neutral-ionic transformation in quasi–one-dimensional prototype crystal of tetrathiafulvalene-chloranil (TTF-CA). We present experimental evidences that the ordering of lattic

A basic theoretical structure for mechanochemical transformations based on prior models for solid-state reactions and HOMO–LUMO (highest occupied molecular orbital–lowest unoccupied molecular orbital) gap closing produces the concept of distortio

Here, we propose an extension of the diabatic approach to photo-induced phase transitions and suggest three states model, which mimics a system with three local diabatic states or equivalently two states where one of them is unstable against a nonsym
