含时Lieb-Liniger气体的Fermi-Bose变换

Fermi-Bose transformation for the time-dependent Lieb-Liniger gas

H. Buljan, R. Pezer, T. Gasenzer

摘要:

构造了描述一维δ相互作用玻色子自由膨胀的Lieb-Liniger(LL)气体的薛定谔方程的精确解。多体波函数是通过变换一个完全反对称(费米子)的时间相关的波函数,它服从薛定谔方程的自由气体。这种变换采用了微分费米玻色映射算子,这取决于相互作用的强度和粒子的数量。

英文摘要:

Exact solutions of the Schrodinger equation describing a freely expanding Lieb-Liniger (LL) gas of delta-interacting bosons in one spatial dimension are constructed. The many-body wave function is obtained by transforming a fully antisymmetric (fermionic) time-dependent wave function which obeys the Schrodinger equation for a free gas. This transformation employs a differential Fermi-Bose mapping operator which depends on the strength of the interaction and the number of particles.
