During recent years we could bear witness to an immense research activity, both in
experimental and theoretical physics, as well as in chemistry, aimed at understanding the …

Most modern physicists and philosophers would agree that a decent interpretation of
quantum mechanics should fullfil at least two criteria. Firstly, it has to elucidate the physical …

Quantum chaos of many-body (MB) systems has been swiftly developing into a vibrant
research area at the interface between various disciplines, ranging from statistical physics to …

Abstract In a recent Letter [Phys. Rev. Lett. 67, 664 (1991)] we found semiclassical
propagation to be remarkably accurate in the chaotic stadium billiard long after classical fine …

The sensitivity of a wave field's evolution to small perturbations is of fundamental interest.
For chaotic systems, there are two distinct regimes of either exponential or Gaussian overlap …

We consider the recently developed semiclassical analysis of the quantum-mechanical
spectral form factor, which may be expressed in terms of classically definable properties …

The theory of scarring of eigenfunctions of classically chaotic systems by short periodic
orbits is extended in several ways. The influence of short-time linear recurrences on …

We discuss two-point correlations of the actions of classical periodic orbits in chaotic
systems. For systems where the semiclassical trace formula is exact and the spectral …

We review recent progress in attaining a quantitative understanding of the scarring
phenomenon, the non-random behaviour of quantum wavefunctions near unstable periodic …

Abstract The Van Vleck–Gutzwiller propagator is a fundamental quantity in semiclassical
theory whose validity was recently demonstrated to extend beyond the time previously …
