| In 1948,Casimir pointed that there is a repulsive interaction between two neutral objects on account of quantum fluctuations of the electromagnetic field. It is known as the Casimir force. Casimir effect plays a role in promoting many physical subjects such as condensed matter physics, quantum electrodynamics, atomic physics, molecular physics, mathematical physics and cosmology.In 1924, the Indian physicist S.Bose derive the Planck blackbody radiation law successfully by supposing that photon is identical particle which is not conservation of number. S. Bose introduced a statistical for analysis the photon. Einstein made Bose's methods spread particles whose quality is not zero further, and predicted if the temperature is low enough, the phase transition will occur, all boson particles will gather to the lowest level, this is the Bose-Einstein Condensation. Bose-Einstein Condensation is known as one of the greatest scientific discoveries in 21st century.This article will briefly give a presentation of Casimir effect, Bose-Einstein condensation of the basic theory and its related research, as well as the thermal field dynamics theory and it's main idea. First we focus Casimir effect at the finite temperature using the thermal field dynamics theory, for the sake of calculating Casimir energy and Casimir force. Next we use numerical methods to given relationship about Casimir force, temperature and distance between Contaminants .Our study not only outreach theory research of the Casimir effect and Bose-Einstein condensation but also supply rationale about the Casimir effect and Bose-Einstein condensation's experimental study. |
