2017年光子-声子相互作用研讨会（Workshop on Photon-phonon interaction: fundamental,material and applications）
2017年 光子-声子相互作用 研讨会
2017/9/22
Photon-phonon interaction in highly confined nanoscale waveguides or microfiber through guided-wave stimulated Brillouin scattering (SBS) has recently emerged as an important area of research. Compar...
Pulsed THz radiation due to phonon-polariton effect in [110] ZnTe crystal
Pulsed THz radiation phonon-polariton effect ZnTe crystal Optics
2012/5/31
Pulsed terahertz (THz) radiation, generated through optical rectification (OR) by exciting [110] ZnTe crystal with ultrafast optical pulses, typically consists of only a few cycles of electromagnetic ...
Temperature-dependent chirped coherent phonon dynamics in Bi$_{2}$Te$_{3}$ using high intensity femtosecond laser pulses
Temperature-dependent chirped coherent phonon dynamics femtosecond laser pulses
2010/11/18
Degenerate pump-probe reflectivity experiments have been performed on a single crystal of
bismuth telluride (Bi2Te3) as a function of sample temperature (3K to 296K) and pump intensity
using ∼...
Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Contribution of interband effects electron-phonon coupling doped polar insulators
2010/11/22
We estimate the contribution of the long-wavelength el–TO–ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytical and numerical res...
Tunable exciton-phonon interactions in an optical lattice of polar molecules
Tunable exciton-phonon interactions optical lattice polar molecules
2010/11/11
We show that an ensemble of polar molecules trapped in an optical lattice can be considered as a controllable open quantum system. The coupling between collective rotational excitations and the center...
Quantum dot Rabi rotations beyond the weak exciton-phonon coupling regime
Quantum dot Rabi rotations weak exciton-phonon coupling regime
2010/10/21
We study the excitonic dynamics of a driven quantum dot under the influence of a phonon
environment, going beyond the weak exciton-phonon coupling approximation. By combining the
polaron transform a...
Polar Optical Phonon Modes and Fröhlich Electron-Phonon Interaction Hamiltonians in Coaxial Cylindrical Quantum Cables
Optical Phonon Modes Coaxial Cylindrical Quantum Cables
2010/4/12
By using the dielectric continuum approximation, the polar optical phonon modes of coaxial cylindrical quantum cables with arbitrary layer-number were studied. In order to describe the vibrating of th...
The Extended Hybrid Model For Optical Phonon Confinement
Hybrid Model Optical Phonon Confinement
2010/4/16
The theory of optical phonons and their confinement in heterostructures is reviewed with analogies made to the theory of acoustic phonons. The dielectric continuum (DC) model is obtained when bulk dis...
