Generating Functional Approach for Spontaneous Coherence in Semiconductor Electron-Hole-Photon Systems
Makoto Yamaguchi, Ryota Nii, Kenji Kamide +2
Electrons, holes, and photons in semiconductors are interacting fermions and bosons. In this system, a variety of ordered coherent phases can be formed through the spontaneous phas…
Second Thresholds in BEC-BCS-Laser Crossover of Exciton-Polariton Systems
Makoto Yamaguchi, Kenji Kamide, Ryota Nii +2
The mechanism of second thresholds observed in several experiments is theoretically revealed by studying the BEC-BCS-laser crossover in exciton-polariton systems. We found that the…
What Determines the Wave Function of Electron-Hole Pairs in Polariton Condensates?
Kenji Kamide, Tetsuo Ogawa
The ground state of a microcavity polariton Bose-Einstein condensate is determined by considering experimentally tunable parameters such as excitation density, detuning, and ultrav…
Evolution of excitons via biexcitons to an electron-hole plasma without level crossing between band edge and exciton in a quantum wire
Masahiro Yoshita, Yuhei Hayamizu, Hidefumi Akiyama +4
A recent single quantum wire is of sufficient quality to reveal new details of the photoluminescence (PL) evolution with increasing electron--hole (e--h) pair density. At a pair de…
