Highly excited exciton-polariton condensates
Tomoyuki Horikiri, Tim Byrnes, Kenichiro Kusudo +7
Exciton-polaritons are a coherent electron-hole-photon (e-h-p) system where condensation has been observed in semiconductor microcavities. In contrast to equilibrium Bose-Einstein…
High-energy side-peak emission of exciton-polariton condensates in high density regime
Tomoyuki Horikiri, Makoto Yamaguchi, Kenji Kamide +9
In a standard semiconductor laser, electrons and holes recombine via stimulated emission to emit coherent light, in a process that is far from thermal equilibrium. Exciton-polarito…
The negative Bogoliubov dispersion in exciton-polariton condensates
Tim Byrnes, Tomoyuki Horikiri, Natsuko Ishida +2
Bogoliubov's theory states that self-interaction effects in Bose-Einstein condensates produce a characteristic linear dispersion at low momenta. One of the curious features of Bogo…
A BCS wavefunction approach to the BEC-BCS crossover of exciton-polariton condensates
Tim Byrnes, Tomoyuki Horikiri, Natsuko Ishida +1
The crossover between low and high density regimes of exciton-polariton condensates is examined using a BCS wavefunction approach. Our approach is an extension of the BEC-BCS cross…
