Spatio-temporal coherent molding and retrieval of pulsed signals in optical waveguides
Nika Durishvili, Ramaz Khomeriki, Vakhtang Jandieri +3
Optical waveguides are key elements for high fidelity, long distance optical communications. Coupled waveguide arrays allow for higher information density, steerting the propagatio…
Photonics of topological magnetic textures
Vakhtang Jandieri, Ramaz Khomeriki, Daniel Erni +4
Topological textures in magnetically ordered materials are important case studies for fundamental research with promising applications in data science. They can also serve as photo…
Conductive domain walls in ferroelectrics as tunable coherent THz radiation source
Ramaz Khomeriki, Kathrin Dörr, Jamal Berakdar
THz emission associated with currents in conductive domains in BiFeO following infrared radiation is theoretically investigated. This experimentally observed phenomenon is expl…
Regular and Chaotic Motion of Two Bodies Swinging on a Rod
Lazare Osmanov, Khomeriki Ramaz
We investigate regular and chaotic dynamics of Two Bodies Swinging on a Rod, which differs from all the other mechanical analogies: depending on initial conditions, its oscillation…
Effective negative specific heat by destabilization of metastable states in dipolar systems
Vazha Loladze, Thierry Dauxois, Ramaz Khomeriki +1
We study dipolarly coupled three dimensional spin systems in both the microcanonical and the canonical ensembles by introducing appropriate numerical methods to determine the micro…
Pulse solutions of the fractional effective models of the Fermi-Pasta-Ulam lattice with long-range interactions
Gervais Nazaire Beukam Chendjou, Jean Pierre Nguenang, Andrea Trombettoni +3
We study analytical solutions of the Fractional Boussinesq Equation (FBE), which is an effective model for the Fermi-Pasta-Ulam (FPU) one-dimensional lattice with long-range coupli…
