Interband anyon plasmon excitations in an alternating-layered interacting anyon gas system

This paper reports that with the use of a self-consistent mean-field theory, where the anyon gauge field is approximated by its expectation value and the Coulomb interaction is calculated in the Hartree approximation the authors have calculated the coupled acoustic anyon plasmon modes for an alternating-layered interacting anyon gas structure. In a single-layer system, we obtain a phonon mode for a noninteracting anyon gas. This is different from the result given by the random-phase approximation. When the Coulomb interaction is included, this phonon mode is suppressed. In a multi-layered system, the authors get an acoustic anyon plasmon mode with its sound velocity renormalized by the Coulomb interaction. The uniform liquid ground state is shown to be stable against solid crystallization
