The appearance of the non-homogeneous structures of the indirect exciton density distribution in the region of the quantum well (in the region of the inner ring) is explained. The structure (the fragmentation) occurs due to the exciton condensed phase formation because of interaction between excitons. The formation of the structure is related with the non-equalibrity of the system, which is caused by the exciton finite lifetime and the presence of the pumpimg. The structure emerges in the shape…

Excitation of pulses of excitonic condensed phase at steady pumping
Abstract. The dynamics of the density of indirect excitons created in a double quantum well heterostructure by a laser illumination are considered and an idea of a generator of the traveling pulses
Spatial structures of islands of electron-hole liquid in semiconductor quantum wells
Abstract The formation of the different structures of islands of electron-hole liquid in the quantum well is studied in a statistical model. The interaction between the islands of electron-hole
Pulses of the Excitonic Condensed Phase in Semiconductors with Double Quantum Well at Steady Pumping
The conditions, under which the generation and movement of solitons (regions of exciton condensed phases) occurs in double quantum wells of semiconductors under a stationary pumping and in the
Dynamics of the excitonic condensed phase pulses in coupled quantum wells
We consider the dynamics of exciton condensed phase pulses in two interacting quantum wells, in which excitons are excited and are acted upon by an external driving force. We use the phenomenological
Charge Density Waves in the Electron–Hole Liquid in Coupled Quantum Wells
A many-component electron–hole plasma is considered in coupled quantum wells. The electrons and the holes are localized in the different wells. It is found in our previous works that the
