Multimode lasing in two-dimensional fully chaotic cavity lasers.
Multimode lasing in a fully chaotic cavity is investigated numerically by using a nonlinear dynamics model. We report a transition process from single-mode lasing to multimode lasing and revealExpand

Theory of two-dimensional microcavity lasers
We present theoretical models of two-dimensional (2D) microcavity lasers. The relation between stationary lasing modes and resonances or metastable states is elucidated for arbitrary shapes of 2DExpand

Chaotic tunneling: a remarkable manifestation of complex classical dynamics in non-integrable quantum phenomena
Abstract The tunneling phenomenon in chaotic systems is analyzed in terms of the complex semi-classical method in the time domain. In contrast to the tunneling paths in integrable systems, it isExpand

Stable oscillations of a spatially chaotic wave function in a microstadium laser.
Laser action on a single spatially chaotic wave function is obtained as a final stable state in a nonlinear dynamical model of a stadium shaped resonant cavity with an active medium. The stableExpand

Asymmetric stationary lasing patterns in 2D symmetric microcavities.
Locking of two resonance modes of different symmetry classes and different frequencies in 2D resonant microcavity lasers is investigated by using a nonlinear dynamical model. The patterns ofExpand

Applicability of symplectic integrator to classically unstable quantum dynamics
Applicability of symplectic integrator (SI) to classically unstable (chaotic) quantum systems is examined, and accuracy and efficiency as a numerical integrator of Schrodinger equation areExpand

Tunneling mechanism due to chaos in a complex phase space.
We have revealed that the barrier-tunneling process in nonintegrable systems is strongly linked to chaos in complex phase space by investigating a simple scattering map model. The semiclassical waveExpand
