度规图上薛定谔算子的真空能

Vacuum energy of Schrödinger operators on metric graphs

J. M. Harrison, K. Kirsten

摘要:

给出了有限度规图上薛定谔算子真空能的积分公式。根据Kostrykin和Schrader的一般方案对图上的局部顶点匹配条件进行了分类。虽然图中的真空能可能包含有限的模糊性,但具有紧支撑势的键上的卡西米尔力是明确定义的。真空能量由图薛定谔算子的zeta函数确定,该函数通过幅角原理从适当的久期方程导出。一个量子图有一个相关的概率经典动力学,一般是遍历和混合。因此,结果提出了这个准一维量子系统,这是经典混沌的真空能量的解析公式。

英文摘要:

We present an integral formulation of the vacuum energy of Schrödinger operators on finite metric graphs. Local vertex matching conditions on the graph are classified according to the general scheme of Kostrykin and Schrader. While the vacuum energy of the graph can contain finite ambiguities the Casimir force on a bond with compactly supported potential is well defined. The vacuum energy is determined from the zeta function of the graph Schrödinger operator which is derived from an appropriate secular equation via the argument principle. A quantum graph has an associated probabilistic classical dynamics which is generically both ergodic and mixing. The results therefore present an analytic formulation of the vacuum energy of this quasi-one-dimensional quantum system which is classically chaotic.
