Higher-Order Harmonic Generation caused by Elliptically Polarized Electric Fields in Solid-State Materials
T. Tamaya, A. Ishikawa, T. Ogawa +1
We theoretically investigated the dependence of higher-order harmonic generation (HHG) in solid-state materials on the ellipticity of the electric field. We found that in the multi…
Decomposition of radiation energy into work and heat
Tatsuro Yuge, Makoto Yamaguchi, Tetsuo Ogawa
We investigate energy transfer by the radiation from a cavity quantum electrodynamics (QED) system in the context of quantum thermodynamics. We propose a method of decomposing it i…
Markovian Quantum Master Equation beyond Adiabatic Regime
Makoto Yamaguchi, Tatsuro Yuge, Tetsuo Ogawa
By introducing a temporal change timescale for the time-dependent system Hamiltonian, a general formulation of the Markovian quantum master equation is given to g…
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…
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…
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…
