BCS模型的亚稳定性

Metastability in the BCS model

Joris Lauwers, Andre Verbeure

摘要:

本文讨论了强耦合BCS模型的平均场版本中的亚稳态,并研究了在细致平衡w.r. t中超导平衡态在Lindblad生成元动力学半群作用下的演化。另一种平衡态。中间状态明确地构造和它们的稳定性性质的推导。在这个真正的量子系统的亚稳性的概念,表示通过能量熵平衡不等式和规范坐标的观测量。

英文摘要:

We discuss metastable states in the mean-field version of the strong coupling BCS-model and study the evolution of a superconducting equilibrium state subjected to a dynamical semi-group with Lindblad generator in detailed balance w.r.t. another equilibrium state. The intermediate states are explicitly constructed and their stability properties are derived. The notion of metastability in this genuine quantum system, is expressed by means of energy-entropy balance inequalities and canonical coordinates of observables.
