玻尔-索末菲量子化定则的再探讨:正量子化方法

Bohr-Sommerfeld quantization rules revisited: the method of positive commutators

Abdelwaheb Ifa, Hanen Louati, Michel Rouleux

摘要:

我们重新审视了著名的玻尔-索末菲量子化规则(BS)的代数和微观局部框架内的1-D伪微分自伴哈密顿Helffer和Sjöstrand; BS持有时,格兰姆矩阵组成的标量积的一些WKB解决方案的“通量范数”是不可逆的。这个过程的兴趣在于它可能推广到矩阵值哈密顿,如Bogoliubov-de Gennes哈密顿。在标量情况下,通过使用作用角变量,它被简化。

英文摘要:

We revisit the well known Bohr-Sommerfeld quantization rule (BS) for a 1-D Pseudo-differential self-adjoint Hamiltonian within the algebraic and microlocal framework of Helffer and Sjöstrand; BS holds precisely when the Gram matrix consisting of scalar products of some WKB solutions with respect to the "flux norm" is not invertible. The interest of this procedure lies in its possible generalization to matrix-valued Hamiltonians, like Bogoliubov-de Gennes Hamiltonian. It is simplified in the scalar case by using action-angle variables.
