Underwater electrical explosion of wire arrays is a promising method of obtaining extreme states of water (T > 1 eV, P > 1010 TPa). These extreme states are obtained in the vicinity of implosion of strong converging shock waves generated by the array explosion. Explosions of cylindrical and spherical wire arrays were studied in which the latter results in higher water parameters due to the shock...
A brief review of the results obtained in recent research of underwater electrical explosions of wires and wire arrays using microsecond-, submicrosecond-, and nanosecond-timescale high-current generators is presented. In a microsecond-timescale wire explosion, good agreement was attained between the results of experiments and the results of magnetohydrodynamic calculations coupled with equations...
We show that a partially coherent beam can be self-trapped into an incoherent soliton with all its coherent components embedded in the continuum. Incoherent embedded solitons display distinctive power spectrum and coherence properties.
We propose emitter of high-order harmonics that is driven by a low-power continues-wave laser. The driving field is enhanced within a micro-resonator and further focused into sub-wavelength hot-spots by plasmonic nano-particles that are located near its surface.
