Nonequilibrium theory of the conversion-efficiency limit of solar cells including thermalization and extraction of carriers
Kenji Kamide, Toshimitsu Mochizuki, Hidefumi Akiyama +1
The ideal solar cell conversion efficiency limit known as the Shockley-Queisser (SQ) limit, which is based on a detailed balance between absorption and radiation, has long been a t…
Generation method of a photonic NOON state with quantum dots in coupled nanocavities
Kenji Kamide, Yasutomo Ota, Satoshi Iwamoto +1
We propose a method to generate path-entangled -state photons from quantum dots (QDs) and coupled nanocavities. In the systems we considered, cavity mode frequencies are tune…
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…
Eigenvalue decomposition method for photon statistics of frequency filtered fields and its applications to quantum dot emitters
Kenji Kamide, Satoshi Iwamoto, Yasuhiko Arakawa
A simple calculation method for photon statistics of frequency-filtered fields is proposed. This method, based on eigenvalue decompositions of superoperators, allows us to study ef…
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…
Impact of the dark path on quantum dot single photon emitters in small cavities
Kenji Kamide, Satoshi Iwamoto, Yasuhiko Arakawa
Incoherent pumping in quantum dots (QDs) can create a biexciton state through two paths: via the formation of bright or dark exciton states. The latter, dark-pumping, path is shown…
