On the foundations of a new approach to statistical mechanics of classical systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 3, Issue 4, Page 607-674, 1980., 1980
It has been known for a long time that the fundamental approaches to equilibrium and nonequillbrium statistical mechanics available at present lead to physical and mathematical inconsistencies for dense systems. A new approach, whose foundation lies in the more powerful statistical method of counting complexions, had been formulated which not only ...

Active Invisibility Cloaks in One Dimension

open access: yes, 2015
We outline a general method of constructing finite-range cloaking potentials which render a given finite-range real or complex potential $v(x)$ unidirectionally reflectionless or invisible at a wavenumber $k_0$ of our choice.

Light Assisted Collisional Loss in a $^{85/87}$Rb Ultracold Optical Trap

open access: yes, 2008
We have studied hetero- and homonuclear excited state/ground state collisions by loading both $^{85}$Rb and $^{87}$Rb into a far off resonant trap (FORT).

Isospin dependence of nucleon Correlations in ground state nuclei

open access: yes, 2013
The dispersive optical model (DOM) as presently implemented can investigate the isospin (nucleon asymmetry) dependence of the Hartree-Fock-like potential relevant for nucleons near the Fermi energy.

Calculation of the interspecies s-wave scattering length in an ultracold Na-Rb vapor [PDF]

open access: yes, 2003
We report the calculation of the interspecies scattering length for the sodium-rubidium (Na-Rb) system. We present improved hybrid potentials for the singlet $X^1\Sigma^+$ and triplet $a^3\Sigma^+$ ground states of the NaRb molecule, and calculate the ...

Non-localities in nucleon-nucleus potentials

open access: yes, 2007
Two causes of non-locality inherent in nucleon-nucleus scattering are considered. They are the results of two-nucleon antisymmetry of the projectile with each nucleon in the nucleus and the dynamic polarization potential representation of channel ...

Total reaction cross sections from $^{141}$141Pr($\alpha$,$\alpha$)$^{141}$Pr elastic scattering and $\alpha$-induced reaction cross sections at low energies

open access: yes, 2011
Elastic scattering data for $^{141}$Pr($\alpha$,$\alpha$)$^{141}$Pr have been analyzed to derive a new energy-dependent local potential for the $^{141}$Pr-$\alpha$ system. This potential is used successfully to predict the cross section of the $^{141}$Pr(

The seventh blind test of crystal structure prediction: structure ranking methods

open access: yesActa Crystallographica Section B, Volume 80, Issue 6, Page 548-574, December 2024.
The results of the seventh blind test of crystal structure prediction are presented, focusing on structure ranking methods.A seventh blind test of crystal structure prediction has been organized by the Cambridge Crystallographic Data Centre. The results are presented in two parts, with this second part focusing on methods for ranking crystal structures

Fast Frictionless Expansion of an Optical Lattice

open access: yes, 2012
We investigate fast frictionless expansion of an optical lattice with dynamically variable spacing (accordion lattice). We design an expansion trajectory that yields a final state identical to the initial state up to an irrelevant phase factor.
