Coulomb Clusters: Stability and Spectrum of Energy States
نویسنده
چکیده
Coulomb cluster is a phenomenon in classical physics which is under substantial amount of attention. These clusters are characterized by the strong electrostatic interaction of highly charged particle trapped within an external confining potential. Examples of such systems include ion traps and quantum dots. Investigation in this area had been further encouraged in the past few decades with the discovery of complex (dusty) plasmas and the increase in the computer simulation of complex plasma experiments. In discharge complex plasma system, micron-sized dust particles which are highly negatively charged (~10e) repel each other under strong coulomb forces to arrange themselves into well ordered structures. Such structures with limited number of particles are referred as Coulomb clusters in dusty plasma.

متن کاملBeyond the Rayleigh instability limit for multicharged finite systems: from fission to Coulomb explosion.
We address the stability of multicharged finite systems driven by Coulomb forces beyond the Rayleigh instability limit. Our exploration of the nuclear dynamics of heavily charged Morse clusters enabled us to vary the range of the pair potential and of the fissibility parameter, which results in distinct fragmentation patterns and in the angular distributions of the fragments. The Rayleigh insta...
متن کاملCurves of Marginal Stability , and Weak and Strong - Coupling BPS Spectra in N = 2 Supersymmetric QCD
We explicitly determine the global structure of the SL(2;Z) bundle over the Coulomb branch of the moduli space of asymptotically free N = 2 supersymmetric Yang-Mills theories with gauge group SU(2) when massless hypermultiplets are present. For each relevant number of avours, we show that there is a curve of marginal stability on the Coulomb branch, di eomorphic to a circle, across which the BP...
