1 Semi - classical calculations of the two - point correlation form factor for diffractive systems
The computation of the two-point correlation form factor K(τ) is performed for a rectangular billiard with a small size impurity inside for both periodic or Dirichlet boundary conditions. It is demonstrated that all terms of perturbation expansion of this form factor in powers of τ can be computed directly from a semiclassical trace formula. The main part of the calculation is the summation of ...
متن کاملSemiclassical form factor for chaotic systems with spin 1 / 2
We study the properties of the two-point spectral form factor for classically chaotic systems with spin 1/2 in the semiclassical limit, with a suitable semiclassical trace formula as our principal tool. To this end we introduce a regularized form factor and discuss the limit in which the so-called diagonal approximation can be recovered. The incorporation of the spin contribution to the trace f...
متن کاملPeriodic orbits contribution to the 2 - point correlation form factor for pseudo - integrable systems
The 2-point correlation form factor, K 2 (τ), for small values of τ is computed analytically for typical examples of pseudo-integrable systems. This is done by explicit calculation of periodic orbit contributions in the diagonal approximation. The following cases are considered: (i) plane billiards in the form of right triangles with one angle π/n and (ii) rectangular billiards with the Aharono...

15 صفحه اولSemiclassical form factor of matrix element fluctuations.
We analyze within a semiclassical approximation the form factor for the fluctuations of quantum matrix elements around their classical average. We find two contributions. One is proportional to the form factor for the density of states, with an amplitude determined by the squared average of the matrix elements. The other is constant and related to the fluctuations of finite time classical traje...
