Q-boson interferometry and generalized Wigner function

Abstract

Bose-Einstein correlations of two identically charged Qbosons are derived considering these particles to be confined in finite volumes. Boundary effects on single Q-boson spectrum are also studied. We illustrate the effects on the spectrum and on the two-Q-boson correlation function by means of two toy models. We also derive a generalized expression for the Wigner function depending on the deformation parameter Q, which is reduced to its original functional form in the limit of Q → 1.

A molecular dynamics study of bond strength and interface conditions in the Al/Al2O3 metal–ceramic composites

“…where E bond , E Coulomb , E vdWaals and E over stand for the bond energy directly derived from bond orders, Coulomb interactions calculated between all atom pairs with the atomic charges, van der Waals energies and over-coordination energy term, respectively [26].…”

“…This characteristic is particularly helpful in the modeling of atomic bonds in the Al=Al 2 O 3 interface, where both metallic and ionic atomic bonds are present. It is also sufficiently general to be able to describe both metallic and ionic bonds between Al and O elements [26]. Furthermore, it is well suited to be used in commercial software and open source MD programs such as LAMMPS [27].…”

HBT interferometry: historical perspective

“…For the CE case, we use Eq. (60) and (62), writing the four-divergence and the integrals in cylindrical coordinates, using the symmetry of the problem, which leads to a simpler expression:…”
