Photoinduced Enhancement of the Excitonic Order in Strongly Correlated Electron Systems with the Spin Crossover

Orlov, Y.S., Nikolaev, S.V., Ovchinnikov, S.G.// JETP Letters//

A new mechanism of the photoinduced enhancement of the excitonic order in strongly correlated electron systems with the spin crossover through the generation of a massive mode in the spectrum of collective excitations is demonstrated.
