Shock shells in Coulomb explosions of nanoclusters.
We predict that Coulomb explosion of a nanoscale cluster, which is ionized by high-intensity laser radiation and has a naturally occurring spatial density profile, will invariably produce shock waves. In most typical situations, two shocks, a leading and a trailing one, form a shock shell that eventually encompasses the entire cluster. Being the first example of shock waves on the nanometer sca...
متن کاملNuclear fusion driven by coulomb explosions of large deuterium clusters
Recent experiments on the interaction of intense, ultrafast laser pulses with large van der Waals bonded clusters have shown that these clusters can explode with substantial kinetic energy. By driving explosions in deuterium clusters with a 35 fs laser pulse, we have accelerated ions to sufficient kinetic energy to produce DD nuclear fusion. By diagnosing the fusion yield through measurements o...
متن کاملPlasma crystal: Coulomb crystallization in a dusty plasma.
A macroscopic Coulomb crystal of solid particles in a plasma has been observed. Images of a cloud of 7-p,m "dust" particles, which are charged and levitated in a weakly ionized argon plasma, reveal a hexagonal crystal structure. The crystal is visible to the unaided eye. The particles are cooled by neutral gas to 310 K, and their charge is >9800e, corresponding to a Coulomb coupling parameter r...
متن کاملIdeal Coulomb Plasma Approximation in Line Shape Models: Problematic Issues
In weakly coupled plasmas, it is common to describe the microfield using a Debye model. We examine here an “artificial” ideal one-component plasma with an infinite Debye length, which has been used for the test of line shape codes. We show that the infinite Debye length assumption can lead to a misinterpretation of numerical simulations results, in particular regarding the convergence of calcul...
متن کاملStructural analysis of a Coulomb lattice in a dusty plasma.
Pair and bond-orientational correlation functions and structure factors, asused in colloidal science, are applied as quantitative indicators of the phase of the newly discovered "plasma crystals." These Coulomblattice structures are formed by charged microspheres levitated in glow discharge plasmas and are imaged photographically. Static structural analysis is demonstrated on the experimental d...
