Low-temperature electron mobility in doped semiconductors with high dielectric constant
Khachatur G. Nazaryan, Mikhail Feigel'man
We propose and study theoretically a new mechanism of electron-impurity scattering in doped seminconductors with large dielectric constant. It is based upon the idea of \textit{vec…
Electron-phonon cooling power in Anderson insulators
Mikhail V. Feigel'man, Vladimir E. Kravtsov
First microscopic theory for electron-phonon energy exchange in Anderson insulators is developed. The major contribution to the cooling power as a function of electron temperature…
Dielectric response of Anderson and pseudogapped insulators
M. V. Feigel'man, D. A. Ivanov, E. Cuevas
Using a combination of analytic and numerical methods, we study the polarizability of a (non-interacting) Anderson insulator in one, two, and three dimensions and demonstrate that,…
Thermal transport in disordered one-dimensional spin chains
Igor Poboiko, Mikhail Feigel'man
We study one-dimensional anisotropic XY-Heisenberg spin- chain with weak random fields by means of Jordan-Wigner transformation to spinless Luttinger liq…
Magnetic field-induced giant enhancement of electron-phonon energy transfer in strongly disordered conductors
A. V. Shtyk, M. V. Feigel'man, V. E. Kravtsov
Relaxation of soft modes (e.g. charge density in gated semiconductor heterostructures, spin density in the presence of magnetic field) slowed down by disorder may lead to giant enh…
Tunneling conductance due to discrete spectrum of Andreev states
P. A. Ioselevich, M. V. Feigel'man
We study tunneling spectroscopy of discrete subgap Andreev states in a superconducting system. If the tunneling coupling is weak, individual levels are resolved and the conductance…
