Phonon spectral functions of photo-generated hot carrier plasmas: effects of carrier screening and plasmon-phonon coupling
Kyung-Soo Yi, Hye-Jung Kim
We investigate spectral behavior of phonon spectral functions in an interacting multi-component hot carrier plasma. Dielectric polarization functions are formulated so that they sa…
Spectral analysis on a phonon spectral function of a solid-state plasma in a doped semiconductor
Kyung-Soo Yi, Hye-Jung Kim
We report an analysis on a phonon spectral function of a solid-state plasma formed in a doped semiconductor. Real and imaginary parts of phonon propagators are evaluated including…
Dielectric response functions of multi-component hot carrier plasmas
Kyung-Soo Yi, Hye-Jung Kim
Dielectric responses of a multi-component plasma are investigated at finite temperature considering the case of optically generated carriers in a wurtzite GaN. The effective dielec…
The Hierarchy of Incompressible Fractional Quantum Hall States
John J. Quinn, Arkadiusz Wójs, Kyung-Soo Yi +1
The correlations that give rise to incompressible quantum liquid (IQL) states in fractional quantum Hall systems are determined by the pseudopotential describing th…
Symmetry relations for spin-resolved exchange correlation kernels in soft magnetic layered systems
Ina Yeo, Kyung-Soo Yi
We first exploit the physical condition satisfying the symmetry relation of the ``exact'' spin-resolved exchange correlation kernel based on the ``mixed scheme'' in soft magnetic l…
Physical condition and spin-resolved exchange correlation kernels in an inhomogeneous many electron system
Ina Yeo, Kyung-Soo Yi
We first exploit the spin symmetry relation for the exact exchange correlation kernel in an inhomogen…
