匀强磁场与简谐势阱中的低维荷电自旋－1玻色气体
Low-dimensional charged spin-1 Bose gases in uniform magnetic field and harmonic trap
摘要
Abstract
The phase transition and magnetic properties of low-dimensional charged spin-1 bosons under mag-netic field and harmonic trap are studied with truncated-summation approach ( TSA) and semi-classical ap-proximation ( SCA) , taking two dimensional ideal Bose gas as an example.It is indicated that the Bose-Einstein condensation ( BEC) critical temperature first slightly increases and then slowly decreases with the increasing magnetic field due to the competition between charge -and spin -magnetic field interactions.The TSA can make a well improvement to the SCA.Finally, a crossover from diamagnetism to paramagnetism and relations of the critical value of spin factor as a function of magnetic field and temperature are discussed.关键词
