Reply to Comment on "System-environment coupling derived by Maxwell's boundary conditions from the weak to the ultrastrong light-matter-coupling regime"
Motoaki Bamba, Tetsuo Ogawa
As mentioned by Simone De Liberato [arXiv:1307.5615], when we suppose the metallic thin mirror and perform the renormalization additionally to the approach starting from the freque…
Excitons and biexcitons in symmetric electron-hole bilayers
Ryo Maezono, Pablo López Ríos, Tetsuo Ogawa +1
Symmetric electron-hole bilayer systems have been studied at zero temperature using the diffusion quantum Monte Carlo method. A flexible trial wave function is used that can descri…
A recipe for Hamiltonian of system-environment coupling applicable to ultrastrong light-matter interaction regime
Motoaki Bamba, Tetsuo Ogawa
When the light interacts with matters in a lossy cavity, in the standard cavity quantum electrodynamics, the dissipation of cavity fields is characterized simply by the strengths o…
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…
System-environment coupling derived by Maxwell's boundary conditions from weak to ultrastrong light-matter coupling regime
Motoaki Bamba, Tetsuo Ogawa
In the standard theory of cavity quantum electrodynamics (QED), coupling between photons inside and outside a cavity (cavity system and photonic reservoir) is given conserving the…
First-order superfluid-Mott-insulator transition for quantum optical switching in cavity QED arrays with two cavity modes
Kenji Kamide, Makoto Yamaguchi, Takashi Kimura +1
We theoretically investigated the ground states of coupled arrays of cavity quantum electrodynamical (cavity QED) systems in presence of two photon modes. Within the Gutzwiller-typ…
