Tristability in the pendula chain
Ramaz Khomeriki, Jerome Leon
Experiments on a chain of coupled pendula driven periodically at one end demonstrate the existence of a novel regime which produces an output frequency at an odd fraction of the dr…
Self-Chaotization in Coupled Optical Waveguides
Ramaz Khomeriki, Archil Ugulava, Levan Chotorlishvili
We consider theoretically two coupled optical waveguides with a varying barrier height along the waveguides direction. The barrier could be constructed by the elongated island with…
Stochastic Resonance in the Fermi-Pasta-Ulam Chain
George Miloshevich, Ramaz Khomeriki, Stefano Ruffo
We consider a damped -Fermi-Pasta-Ulam chain, driven at one boundary subjected to stochastic noise. It is shown that, for a fixed driving amplitude and frequency, increasing the…
Trapping of Nonlinear Gravitational Waves by Two-Fluid Systems
Merab Gogberashvili, Ramaz Khomeriki
We show that the coupled two-fluid gravitating system (e.g. stiff matter and 'vacuum energy') could trap nonlinear gravitational waves (e.g. Einstein-Rosen waves). The gravitationa…
