研究業績内容

Development of the theory of electron-phonon interaction in mixed valence materials which succeeded in quantitative description of the phonon spectra and magnetic neutron scattering spectra. Development of the theory of the interplay between heavy fermions and crystal field excitations in Kondo lattice. Development of the the Stochastic Optimization Method (Stochastic Sampling Method) for the analytic continuation from the imaginary times to the real frequencies. Development of Diagrammatic Monte Carlo algorithms for the problems of Pseudo-Jahn-Teller polaron, exciton, exciton-polaron, t-J-Holstein polaron, polaron in the external field etc. Discovery of the fact that the Franck-Condon shake off peak of the spectral function of polaron in the strong coupling regime inherits it's dispersion from the noninteracting particle.
Published papers more than 60, including 9 Phys. Rev. Lett. articles.
