Some Remarks about Semiclassical Trace Invariants and Quantum Normal Forms

چکیده
In this paper we explore the connection between semi-classical and quantum Birkhoff canonical forms (BCF) for Schrödinger operators. In particular we give a ”non-symbolic” operator theoretic derivation of the quantum Birkhoff canonical form and provide an explicit recipe for expressing the quantum BCF in terms of the semi-classical BCF.

Periodic orbit bifurcations and scattering time delay fluctuations
We study fluctuations of the Wigner time delay for open (scattering) systems which exhibit mixed dynamics in the classical limit. It is shown that in the semiclassical limit the time delay fluctuations have a distribution that differs markedly from those which describe fully chaotic (or strongly disordered) systems: their moments have a power law dependence on a semiclassical parameter, with ex...
متن کاملSemiclassical Quantization of Circular Billiard in Homogeneous Magnetic Field: Berry-tabor Approach
Semiclassical methods are accurate in general in leading order of , since they approximate quantum mechanics via canonical invariants. Often canonically noninvariant terms appear in the Schrödinger equation which are proportional to 2, therefore a discrepancy between different semiclassical trace formulas in order of 2 seems to be possible. We derive here the Berry-Tabor formula for a circular ...
متن کاملOn Some Applications of Time-dependent Invariants to the Semiclassical Formulation of Quantum Mechanics
I t i s shown, that time-dependent c lass ica l and quantum mechanical invariants (TDI) may be of considerable value in semiclassical formulations of time-dependent quantum mechanical problems. We demonstrate, that the application of TDI allows the application of several ground-state technologies as for instance the Wigner-Kirkwood and WKB-expansion to the TD s i tua t ion . Possible applicatio...
متن کاملBirkhoff Normal Forms in Semi-classical Inverse Problems
The purpose of this note is to apply the recent results on semi-classical trace formulæ [17], and on quantum Birkhoff normal forms for semi-classical Fourier Operators [12] to inverse problems. We show how the classical Birkhoff normal form can be recovered from semi-classical spectral invariants. In fact the full quantum Birkhoff normal form of the quantum Hamiltonian near a closed orbit, and ...
متن کاملAccuracy of Trace Formulas
Using quantum maps we study the accuracy of semiclassical trace formulas. The role of chaos in improving the semiclassical accuracy, in some systems, is demonstrated quantitatively. However, our study of the standard map cautions that this may not be most general. While studying a sawtooth map we demonstrate the rather remarkable fact that at the level of the time one trace even in the presence...
