GENERALIZATION OF CLASSICAL STATISTICAL MECHANICS TO QUANTUM MECHANICS AND STABLE PROPERTY OF CONDENSED MATTER [PDF]
Modern Physics Letters B, 2004 Classical statistical average values are generally generalized to average values of quantum mechanics. It is discovered that quantum mechanics is a direct generalization of classical statistical mechanics, and we generally deduce both a new general continuous eigenvalue equation and a general discrete eigenvalue equation in quantum mechanics, and ...

Non-recursive chadi-cohen integration over the brillouin zone of cubic crystals [PDF]
Philosophical Magazine B, 2001 Abstract We give closed-form non-recursive formulae for the Chadi-Cohen sets of special points associated with the bcc and fcc symmetries. The expressions are valid for arbitrary order n, which enters them as a parameter. This ameliorates the situation of the Chadi-Cohen method of integration over Brillouin zones, whose application to high-precision ...

Meson Condensations in High-Density Matter [PDF]
Prog.Theor.Phys.Suppl.153:174-189,2004, 2003 Recent studies on meson condensations (pions and kaons) in high-density hadronic matter are reviewed. After summarizing onset mechanisms of pion and kaon condensations, we discuss implications for neutron star phenomena such as rapid cooling through neutrino emission, static and dynamic properties of neutron stars. Recent studies on coexistence problem

Philosophical Magazine B, 2001 Abstract The behaviour of two-dimensional grain structures anchored by circular or elongated pins (needles) is examined in two ways: experimentally, using soap films trapped between two glass plates, and computationally, using a Potts model. In the simulations, the Zener pins are exactly equivalent in size, position and orientation to the pins in the ...

Gravitational collapse of Bose-Einstein condensate dark matter halos [PDF]
Phys. Rev. D 89, 084040, 2014, 2014 We study the mechanisms of the gravitational collapse of the Bose-Einstein condensate dark matter halos, described by the zero temperature time-dependent nonlinear Schr\"odinger equation (the Gross-Pitaevskii equation), with repulsive inter-particle interactions.

Optically controlled polariton condensate molecules [PDF]
Phys. Rev. B 103, 115309 (2021), 2020 A condensed matter platform for analogue simulation of complex two-dimensional molecular bonding configurations, based on optically trapped exciton-polariton condensates is proposed. The stable occupation of polariton condensates in the excited states of their optically configurable potential traps permits emulation of excited atomic orbitals.

On the mechanical properties of matter waves [PDF]
J Phys B 37 (2004) L293, 2004 Electromagnetic waves and fluids have locally conserved mechanical properties associated with them and we may expect these to exist for matter waves. We present a semiclassical description of the continuity equations relating to these conserved properties of matter waves and derive a general expression for their respective fluxes.

Matter-wave solitons supported by dissipation [PDF]
, 2005 We show how novel types of long-lived self-localized matter waves can be constructed with Bose-Einstein condensates. The ingredients leading to such structures are a spatial phase generating a flux of atoms towards the condensate center and the dissipative mechanism provided by the inelastic three-body collisions in atomic Bose-Einstein condensates ...

Chiral condensate in neutron matter [PDF]
Phys.Lett.B671:25-29,2009, 2008 A recent chiral perturbation theory calculation of the in-medium quark condensate $<\bar q q>$ is extended to the isospin-asymmetric case of pure neutron matter. In contrast to the behavior in isospin-symmetric nuclear matter we find only small deviations from the linear density approximation.
