(19990524)We have applied the exchange Monte Carlo method to the ordering dynamics of the threestate Potts model with conserved order parameter. Even for the deeply quenched case to low temperatures, we have observed a rapid domain ...

(20000413)Calculations of the hydrogen molecular continuum , where the latter is repulsive) have been carried out in the wavelength range 120  600 nm, based on potential curves and reduced masses. They give transition probabilities, ...

(20000414)In order to investigate the electronic characteristics of ferroelectric thin films that behave as semiconductors, we derive an equation to calculate the band bending in ferroelectrics, to replace the Poisson equation. We ...

(19991209)Changes in pion production as a function of the impact parameter of the collision or the incident energy, may reveal characteristics of a possible firstorder phase transition from nuclear to quark matter, as predicted by ...

(20000301)Using approximate techniques we study the final moments of the collision of two (individually nonspinnning) black holes which inspiral into each other. The approximation is based on treating the whole spacetime as a single ...

(20000901)Using the Paul trap as a model, we point out that the same wavefunctions can be variously coherent or squeezed states, depending upon the system to which they are applied.

(20000713)An overview of the searches for weak interacting massive particles (WIMPs) through detection of their scattering off various target nuclei carried out in the Canfranc Tunnel Astroparticle Laboratory (at 675 and at 2450 ...

(19991110)We introduce a new colloidal probe technique to study local and long range motions of semiflexible actin filaments along their reptation tube axis in entangled networks. Single test filaments decorated with colloidal gold ...

(20000131)A combined statistical analysis of the experimental results of the LSND and KARMEN µe oscillation search is presented. LSND has evidence for neutrino oscillations that is not confirmed by the KARMEN experiment. However, ...

(19991110)We have fabricated using highresolution electron beam lithography circular magnetic particles (nanomagnets) of diameter 60 nm and thickness 7 nm out of the common magnetic alloy supermalloy. The nanomagnets were arranged ...

(20001201)Novel methods are discussed for the state control of atoms coupled to singlemode and multimode cavities and microspheres. (1) Excitation decay control: The quantum Zeno effect, i.e. inhibition of spontaneous decay ...

(19990526)A new simulation program for Rutherford backscattering spectroscopy (RBS) together with an adaptive kernel method in the Bayesian probability theory framework was applied to the analysis of RBS data. Reconstructed depth ...

(20000901)We describe the decoherencefree subspace of N atoms in a cavity, in which decoherence due to the leakage of photons through the cavity mirrors is suppressed. We show how the states of the subspace can be entangled with the ...

(19991126)The forceextension measurements on simple poly(ethylene glycol) molecules by Oesterfelt et al in different solvents can be quantitatively explained based on ab initio quantum mechanical calculations of the potential energy ...

(20000701)We utilized a local density functional potential, the linear combination of atomic orbital (LCAO) method, and the BZW procedure to study the electronic structure of 3C and 4HSiC. We present the calculated energy bands, ...

(19990728)The influence of topological constraints on the local dynamics in crosslinked polymer melts and their contribution to the elastic properties of rubber elastic systems are long standing problems in statistical mechanics. ...

(20000901)Dynamical stabilization properties of error avoiding quantum codes are investigated beyond the perturbative regime. As an example Grover's search algorithm and its behaviour under a particular class of coherent errors ...

(20001101)We study the plasmon resonances for small twodimensional silver particles (nanowires) with elliptical or triangular shapes in the 20 nm size range. While the elliptical particle has only two resonances, a well known ...

(20000713)A reanalysis of EGRET data by Dixon et al has led to the discovery of a statistically significant diffuse ray emission from the galactic halo. We show that this emission can naturally be accounted for within a ...

(20001001)We study the dynamics of an elastic rodlike filament in two dimensions, driven by internally generated forces. This situation is motivated by cilia and flagella which contain an axoneme. These hairlike appendages of ...
