Theoretical progress in the research of photoinduced phase transitions is reviewed with
closely related experiments. After a brief introduction of stochastic evolution in statistical …

Two-dimensional quarter-filled organic solids are a promising class of materials to realize
the strongly correlated insulating states called dimer Mott insulator and charge order. In their …

This paper reviews charge ordering in the organic conductors, β ″-(BEDT-TTF)(TCNQ), θ-
(BEDT-TTF) 2X, and α-(BEDT-TTF) 2X. Here, BEDT-TTF and TCNQ represent bis …

Photoinduced melting of horizontal-stripe charge orders in quasi-two-dimensional organic
conductors θ-(BEDT-TTF) 2 RbZn (SCN) 4 [BEDT-TTF= bis (ethylenedithio) …

Charge ordering with structural distortion in quasi-two-dimensional organic conductors θ-
(ET) 2 RbZn (SCN) 4 (ET= BEDT-TTF) and α-(ET) 2 I 3 is investigated theoretically. By using …

To elucidate the different photoinduced melting dynamics of charge orders observed in the
quasi-two-dimensional organic conductors θ-(BEDT-TTF) 2 RbZn (SCN) 4 and α-(BEDT …

Using the Lanczos exact-diagonalization and density-matrix renormalization-group
methods, we study the extended Hubbard model at quarter filling defined on the anisotropic …

We have measured the current-voltage (IV) characteristics, dielectric properties, and
magnetoresistances of insulating layered organic crystals θ-(BEDT-TTF) 2 M Zn (SCN) 4 …

Combined effects of electron correlations and lattice distortions on the charge ordering in θ-
(BEDT-TTF) 2 Rb Zn (SCN) 4 are investigated theoretically in a two-dimensional 3∕ 4-filled …
