We can think of a simple and intuitive scenario for this transition in such a way as is schematically shown in Fig.

That is, a single photon can make a single neutral pair, and after that, Author: Keiichiro Nasu, Hideo Mizouchi, Huai Ping. (a) The phase transition can start when the atom is not only in the excited state but also in the ground state.

In the case of strong interaction between atoms (large value of k), the process of phase transition may begin only when the atom is in the excited by: 7. Theories of photoinduced phase transitions have developed along with the progress in experimental studies, especially concerning their nonlinear characters and transition dynamics.

34–   Itinerant type quantum many-body theories for photo-induced structural phase transitions (PSPTs) are reviewed in close connection with various recent experimental results related to this new optical phenomenon.

There are two key concepts: the hidden multi-stability of the ground state, and the proliferations of optically excited by: The phase transition is caused by a metal-to-metal charge transfer from Mn II to Fe III and a Jahn–Teller distortion of the produced Mn III ion.

At the ferromagnetic state in LT phase of 2, the photo-induced phase transition is observed, i.e., magnetization is quenched by the irradiation with only one shot of laser pulse.

The Classical Approach to Structural Phase Transitions Antiferrodistortive Transitions The classical theory of phase transitions is built upon the Landau theory of expanding the free energy in a power series9 developed in A simplified form of this theory can be obtained if the displacement occurring at a phase transition has three.

For the photoinduced ionic→neutral phase transition in the organic charge transfer crystal TTF-CA, we, at first, theoretically propose an adiabatic path of this transition, which starts from a single charge transfer exciton in ionic phase, but finally reaches a neutral domain with a macroscopic size.

In the next, using a more simplified model, we theoretically study the nonequilibrium. Following the initial ultrafast photo-induced structural phase transit20,21,22,23, the optical excitation creates an unstable high-energy monoclinic (M) state, where the energy supplying the latent heat has already been stored in the system before the transition by: While d-d transitions are in principle forbidden by symmetry, they become weakly-allowed in a crystal when the symmetry is broken by structural relaxations or other effects.

Absorption of a photon resonant with a d - d transition leads to the creation of an electron-hole pair on a single atomic site, which can be treated as a Frenkel exciton.
