Dicke Superradiance in a magnetoplasma
Tobias Brandes, Jun'ichi Inoue, Akira Shimizu
We present theoretical results for superradiance, i.e. the collective coherent decay of a radiating system, in a semiconductor heterostructure under a strong quantizing magnetic fi…
Dicke-superradiance in electronic systems coupled to reservoirs
T. Brandes, J. Inoue, A. Shimizu
We present theoretical results for superradiance, i.e. the collective coherent decay of a radiating system, in semiconductor structures. An optically active region can become super…
Pump Built-in Hamiltonian Method for Pump-Probe Spectroscopy
Jun-ichi Inoue, Akira Shimizu
We propose a new method of calculating nonlinear optical responses of interacting electronic systems. In this method, the total Hamiltonian (system + system-pump interaction) is tr…
Renormalized Bosonic Interaction of Excitons
Jun-ichi Inoue, Tobias Brandes, Akira Shimizu
An effective bosonic Hamiltonian of excitons with ``spin'' degrees of freedom in two dimension is obtained through a projection procedure, starting from a conventional electro…
Strong Enhancement of Superconducting Correlation in a Two-Component Fermion Gas
Masaki Shigemori, Akira Shimizu, Tobias Brandes +1
We study high-density electron-hole (e-h) systems with the electron density slightly larger than the hole density. We find a new superconducting phase, in which the excess electron…
