作为开放量子系统的冷、稀、囚禁玻色子

Cold, dilute, trapped bosons as an open quantum system

James Anglin

摘要:

我们提出了一个主方程的约化密度运营商为一个单一的冷,稀,弱相互作用玻色气体的捕获模式,我们得到了运营商的波动耗散关系中的金斯堡-朗道有效势起着物理上透明的作用。我们还确定了一个退相干效应,往往保持对称性,即使有效的潜力有一个“墨西哥帽”的形式。

英文摘要:

We present a master equation governing the reduced density operator for a single trapped mode of a cold, dilute, weakly interacting Bose gas; and we obtain an operator fluctuation-dissipation relation in which the Ginzburg-Landau effective potential plays a physically transparent role. We also identify a decoherence effect that tends to preserve symmetry, even when the effective potential has a ``Mexican hat'' form.
