Statistical physics of power fluctuations in mode locked lasers
Oded Basis, Omri Gat
We present an analysis of the power fluctuations in the statistical steady state of a passively mode locked laser. We use statistical light-mode theory to map this problem to that…
Critical Behavior of Light
Rafi Weill, Amir Rosen, Ariel Gordon +2
Light is shown to exhibit critical and tricritical behavior in passive mode-locked lasers with externally injected pulses. It is a first and unique example of critical phenomena in…
Formation and annihilation of laser light pulse quanta in thermodynamic-like pathway
Boris Vodonos, Rafi Weill, Ariel Gordon +4
We present a theoretical and experimental study of multiple pulse formation in passively mode-locked (PML) lasers. Following a statistical mechanics approach, the study yields a th…
Exact solution of the nonlinear laser passive mode locking transition
Omri Gat, Ariel Gordon, Baruch Fischer
We present the first statistical mechanics study of a passively mode locked laser which includes all the main physical processes, saturable absorption, Kerr nonlinearity, parabolic…
Solution of a statistical mechanics model for pulse formation in lasers
Omri Gat, Ariel Gordon, Baruch Fischer
We present a rigorous statistical-mechanics theory of nonlinear many mode laser systems. An important example is the passively mode-locked laser that promotes pulse operation when…
Semiclassical analysis and the magnetization of the Hofstadter model
O. Gat, J. E. Avron
The magnetization and the de Haas-van Alphen oscillations of Bloch electrons are calculated near commensurate magnetic fluxes. Two phases that appear in the quantization of mixed s…
Anomalous scaling in passive scalar advection: Monte-Carlo Lagrangian trajectories
Omri Gat, Itamar Procaccia, Reuven Zeitak
We present a numerical method which is used to calculate anomalous scaling exponents of structure functions in the Kraichnan passive scalar advection model (R. H. Kraichnan, Phys.…
Multiscaling in passive scalar advection as stochastic shape dynamics
Omri Gat, Reuven Zeitak
The Kraichnan rapid advection model is recast as the stochastic dynamics of tracer trajectories. This framework replaces the random fields with a small set of stochastic ordinary d…
Invading interfaces and blocking surfaces in high dimensional disordered systems
Omri Gat, Zeev Olami
We study the high-dimensional properties of an invading front in a disordered medium with random pinning forces. We concentrate on interfaces described by bounded slope models belo…
