Laser under ultrastrong electromagnetic interaction with matter
Motoaki Bamba, Tetsuo Ogawa
The conventional picture of the light amplification by stimulated emission of radiation (laser) is broken under the ultrastrong interaction between the electromagnetic fields and m…
Stability of polarizable materials against superradiant phase transition
Motoaki Bamba, Tetsuo Ogawa
The possibility of the superradiant phase transition in polarizable materials described by the minimal-coupling Hamiltonian with the longitudinal dipole-dipole interaction is exami…
Cavity-loss induced plateau in coupled cavity QED array
Tatsuro Yuge, Kenji Kamide, Makoto Yamaguchi +1
Nonequilibrium steady states are investigated in a coupled cavity QED array system which is pumped by a thermal bath and dissipated through cavity loss. In the coherent (non-zero p…
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…
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…
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…
Dissipation and detection of polaritons in ultrastrong coupling regime
Motoaki Bamba, Tetsuo Ogawa
We have investigated theoretically a dissipative polariton system in the ultrastrong light-matter coupling regime without using the rotating-wave approximation on system-reservoir…
