Kinetics of exciton photoluminescence in type-II semiconductor superlattices [PDF]

, 2000
The exciton decay rate at a rough interface in type-II semiconductor superlattices is investigated. It is shown that the possibility of recombination of indirect excitons at a plane interface essentially affects kinetics of the exciton photoluminescence ...

An Estimation of the Gamma-Ray Burst Afterglow Apparent Optical Brightness Distribution Function [PDF]

, 2006
By using recent publicly available observational data obtained in conjunction with the NASA Swift gamma-ray burst mission and a novel data analysis technique, we have been able to make some rough estimates of the GRB afterglow apparent optical brightness

T>0 properties of the infinitely repulsive Hubbard model for arbitrary number of holes [PDF]

, 2000
Based on representations of the symmetric group $S_N$, explicit and exact Schr\"odinger equation is derived for $U=\infty$ Hubbard model in any dimensions with arbitrary number of holes, which clearly shows that during the movement of holes the spin ...
