Kicked rotor is a paradigmatic model for classical and quantum chaos in time-dependent
Hamiltonian systems. More than fifty years since the introduction of this model, there is an …

We review the development of random-matrix theory (RMT) during the last fifteen years. We
emphasize both the theoretical aspects, and the application of the theory to a number of …

We present an overview of the current status of transition-state theory and its
generalizations. We emphasize (i) recent improvements in available methodology for …

A contemporary review on the behavior of driven tunneling in quantum systems is
presented. Diverse phenomena, such as control of tunneling, higher harmonic generation …

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 …

The relaxation of few-body quantum systems can strongly depend on the initial state when
the system's semiclassical phase space is mixed; ie, regions of chaotic motion coexist with …

We report the direct observation of quantum dynamical tunneling of atoms between
separated momentum regions in phase space. We study how the tunneling oscillations are …

Since the first attempts to calculate the helium ground state in the early days of Bohr-
Sommerfeld quantization, two-electron atoms have posed a series of unexpected …

We discuss and give evidence for the existence of a new mechanism for quantum dynamical
tunneling. It may occur when a quantum system's underlying classical dynamics are far from …
