Multielectron ionization and Coulomb explosion of methane clusters (CA4)n, A ) H, D, and T, in very intense (I ) 1018-1019 W cm-2) laser fields were studied using classical dynamics simulations. The products of Coulomb explosion involve light A+ ions (p, d, and t nuclei) with energies up to 20 keV, C4+ ions at I ) 1018 W cm-2, and C6+ ions (carbon nuclei) with energies up to 110 keV at I ) 1019...

We have made use of a stepped doping profile to improve the performance of strained-Si ultra-short MOSFETs. Electron mobility curves are calculated by a Monte Carlo simulator including electron quantization and Coulomb scattering, in addition to phonon and surface roughness scattering. In the first part of the paper, the effect of Coulomb scattering due to both interface charges and bulk impuri...

We study Maldacena’s conjecture and the AdS/SYM correspondence on the Coulomb branch. Several interesting aspects of this conjectured AdS/SYM correspondence on the Coulomb branch are pointed out and clarified.

Measurements revealing anomalously large frictional drag at the transition between the weakly and strongly coupled regimes of a bilayer two-dimensional electron system at total Landau level filling factor nu(T)=1 are reported. This result suggests the existence of fluctuations, either static or dynamic, near the phase boundary separating the quantized Hall state at small layer separations from ...

We use Monte Carlo simulations of the 2D one component Coulomb gas on a triangular lattice, to study the depinning transition of a 2D vortex lattice in a commensurate periodic potential. A detailed finite size scaling analysis indicates this transition to be first order. No significant changes in behavior were found as vortex density was varied over a wide range.

The dynamics of light fermions propagating in a spatial direction at high temperatures can be described effectively by a two–dimensional Schrödinger equation with heavy effective mass meff = πT . Starting from QED, we discuss the transition from three– to two– dimensional positronium discussing the latter in detail including relativistic effects. In the case of QCD the problem is similar to tha...

A novel graphical approach for probing multicomponent collective ejection processes is described. Image labeling provides a visual means for identifying ejection partners and their relative momenta, isolating specific decay channels for detailed study and determining initial electronic and/or molecular geometries prior to ejection. The power of the technique is demonstrated by looking at strong...

We consider a Coulomb problem for the modified Stueckelberg equation. For some specific values of parameters, we establish the presence of parasupersymmetry for spin1 states in this problem and give the explicit form of corresponding parasupercharges.

We propose a general capacitive model for an antidot, which has two localized edge states with different spins in the quantum Hall regime. The capacitive coupling of localized excess charges, which are generated around the antidot due to magnetic flux quantization, and their effective spin fluctuation can result in Coulomb blockade, h/(2e) Aharonov-Bohm oscillations, and the Kondo effect. The r...

The dynamic behavior of a bunched one-dimensional crystalline beam is studied theoretically. It is shown that, owing to the existence of momentum dispersion, a Coulomb chain traveling in a storage ring performs a complex periodic oscillation whenever it is exposed to a longitudinal radio-frequency force. The equations of motion are derived to predict the oscillation pattern in an arbitrary latt...
