摘要:

本文研究了玻色子和费米Tonks-Girardeau气体在硬壁阱中的隧穿动力学。利用费米-玻色图,研究了保留在陷阱中的概率的衰减作为粒子数量和端盖δ激光强度的函数。的费米子气体被证明是一个很好的候选人,以研究单粒子类型的非指数衰减的偏差,而玻色子的情况下,一个新的制度的非指数衰减出现由于不同的共振的陷阱的贡献。

英文摘要:

We study the tunneling dynamics of bosonic and fermionic Tonks-Girardeau gases from a hard wall trap, in which one of the walls is substituted by a delta potential. Using the Fermi-Bose map, the decay of the probability to remain in the trap is studied as a function of both the number of particles and the intensity of the end-cap delta laser. The fermionic gas is shown to be a good candidate to study deviations of the non-exponential decay of the single-particle type, whereas for the bosonic case a novel regime of non-exponential decay appears due to the contributions of different resonances of the trap.
