BIEXCITON SQUEEZING DUE TO OPTICAL EXCITON-BIEXCITON CONVERSION
Vo Tinh, Do Huu Nha, Nguyen Ba An · International Journal of Modern Physics B · 2000
We theoretically investigate the evolution of biexcitons from a coherent into a squeezed state in a fully quantum system described by a trilinear Hamiltonian allowing the transition "photons + excitons ⇌ biexcitons". Curious dependences of the direction and degree of biexciton squeezing on the initial states of photons and excitons are obtained. The theoretical results are well reproduced by numerical calculations.
