STUDYING THE SQUEEZING PROPERTIES OF EXCITONS IN THE EVEN AND ODD COHERENT STATES BY THE MECHANISM OF ADDING POLARITON IN SEMICONDUCTOR

2024-07-21T13:10:22+00:00

This paper studies the exciton squeezing properties in the even and odd coherent states by the mechanism of adding polariton. The process of investigating the squeezing effect is based on the squeezed exciton mechanism that does not require a high excitation level. This mechanism is based on the interaction between exciton, photon standards and a two-photon-level impurity atom in a straight bandgap semiconductor. The important point is that the atom must be in an excited state initially, so that when the atom moves from the excited state to the ground state, more photons will be emitted into the interacting system and the exciton squeezing will be stronger. The exciton squeezing more strongly the greater the initial coherence of the photon-exciton. In both even and odd coherent states, it can be seen that the orthogonal amplitude squeezed coefficient depends not only on parameters such as: the ratio of the photon's energy to the exciton's energy, coherence amplitude, but also depends on the number of photons.

NUMERICAL MENTHOD FOR LAYERD CYLINDRICAL CONFIGURATION

2024-07-21T14:24:51+00:00

For the purpose of investigating the physical processes of atomic and molecular systems placed in mediums, we consider a system of layered cylindrical structure. The Green function of cylindrical system is also more complicated then the one of spherical or planar system. It makes calculating the Green function of system more difficult because the Green function has an infinite sum of n-modes and an integral over the entire wave number. The process of numerical calculations requires handling arithmetic over- and under-flow of bessel and hankel functions of complex variables when variables and/or the order of functions are large. In addition, the expression of Green function has the C_i. These coefficients can approach the limit 0/0 or infinity/infinity, it making numerical calculations impossible. In this article, we propose the proceduce to transform T_i matrices in the recurrence-matrices relation to eliminate 0/0 and infinity/infinity forms of coefficients C_i. By doing so, it makes the values of the T_i-matrices no longer the same as their original values but the final result does not change the Green function of system. These transforms are general for any N-layers of cylindrical configuration.
