Research Abstract

We have investigated pure electronic photoinduced phase transitions as ultrafast phenomena. The obtained principal results are as follows. (1) Possibilities of detection of domain formations by synchrotron radiation (X-ray). (2) Domain formations in the two dimension. (3) Features of real-time domain-growth dynamics.
