The research achievements that I have made are in the field of theoretical physics on condensed matters, quantum optics, and quantum electronics. In particular, I have been engaged in the followings.
1. Theory of low-dimensional excitons: I found for the first time that the optical absorption related to exciton scattering states in quasi-one dimension is qualitatively different from those of higher dimensional systems. This has become a standard knowledge in the field of optical condensed matter physics. Moreover, exciton-exciton interaction was analyzed with the new bosonization technique.
2. Theory of the Fermi-edge singularity (FES) in one-dimensional metals: With the use of the 2-band Tomonaga-Luttinger model, we evaluated the critical exponent of the FES, which is an anomaly of optical absorption and luminescence spectra, taking exact account of the electronic correlation.
3. Theory of exciton Mott transition and quantum pair condensation in electron-hole (e-h) systems: As the density of carries increases, the e-h systems change from insulating to metallic. This “exciton Mott transition” was for the first time described successfully by the dynamical mean field theory (DMFT). In addition, electron-hole pair condensation, exciton Bose-Einstein condensation and e-h BCS state, is extensively investigated by the self-consistent T-matrix approximation.
4. Microscopic theory of photoinduced structural phase transitions: New mechanism, called “photoinduced domino mechanism” was proposed to describe microscopically early stage of the photoinduced structural changes in solids. This domino theory is now one of the standard models of the photoinduced phase transitions.
5. Dynamical and stochastic theories of lasers: Chaotic and stochastic properties of lasers with a low-Q cavity were numerically and analytically analyzed. I proposed the Toda-oscillator model of lasers.
6. Theory of continuous measurement in quantum mechanics: Theory of the reduction of wave packet due to continuous measurement was constructed. Continuous photodetection process was analyzed as an example to find the way of decay of the photon number due to measurement backaction depends on the photon fluctuation.
