متن کاملPhonon spectral function of the Holstein polaron
The phonon spectral function of the one-dimensional Holstein model is obtained within weak and strong-coupling approximations based on analytical self-energy calculations. The characteristic excitations found in the limit of small charge-carrier density are related to the known (electronic) spectral properties of Holstein polarons such as the polaron band dispersion. Particular emphasis is laid...
متن کاملControlling thermal emission of phonon by magnetic metasurfaces
Our experiment shows that the thermal emission of phonon can be controlled by magnetic resonance (MR) mode in a metasurface (MTS). Through changing the structural parameter of metasurface, the MR wavelength can be tuned to the phonon resonance wavelength. This introduces a strong coupling between phonon and MR, which results in an anticrossing phonon-plasmons mode. In the process, we can manipu...
متن کاملPolaron percolation in diluted magnetic semiconductors.
We theoretically study the development of spontaneous magnetization in diluted magnetic semiconductors as arising from a percolation of bound magnetic polarons. Within the framework of a generalized percolation theory we derive analytic expressions for the Curie temperature and the magnetization in the limit of low carrier density, obtaining excellent quantitative agreement with Monte Carlo sim...
متن کاملMagnetic, Spinon and Phonon Superconductivities in Cuprates
The disclosure of the magnetic and spinon superconductivities in hole-doped Bi 2 Sr 2 CaCu 2 O 8+x (Bi2212) cuprate raises the question about the origin of the superconductivity in other cuprates and specially in an electron-doped Nd 2-x Ce x CuO 4 (NCCO) cuprate. The superconductivity (SC) in copper-oxide materials or the high-T c superconductivity (HTSC) is an extraordinary phenomenon. The cu...
