Total destruction of invariant tori for the generalized FrenkelKontorova model
Xifeng Su and Lin Wang
We consider generalized FrenkelKontorova models on higher dimensional lattices. We show that the invariant tori which are parameterized by continuous hull functions can be destroyed by small perturbations in the C topology with r < 1. ... [J. Math.

Destruction of Adiabatic Invariance for Billiards in a Strong Nonuniform Magnetic Field
A. I. Neishtadt and A. V. Artemyev
We study a classical billiard of charged particles in a strong nonuniform magnetic field. We provide an adiabatic description for skipping motion along the boundary of the billiard. We show that a sequence of many changes of regimes of motion from skipping to motion without collisions with the bound ... [Phys. Rev. Lett. 108, 064102 ] published .
Phase transitions in crowd dynamics of resource allocation
Asim Ghosh, Daniele De Martino, Arnab Chatterjee, Matteo Marsili, and Bikas K. Chakrabarti
We define and study a class of resource allocation processes where gN agents, by repeatedly visiting N resources, try to converge to an optimal configuration where each resource is occupied by at most one agent. The process exhibits a phase transition, as the density g of agents grows, from an absor ... [Phys. Rev. E 85, 021116 ] published .
Calculated fission yields of neutron-deficient mercury isotopes
Peter Moller, Jorgen Randrup, and Arnold J. Sierk
The recent unexpected discovery of asymmetric fission of Hg following the electron-capture decay of Tl has led to intense interest in experimentally mapping the fission-yield properties over more extended regions of the nuclear chart and compound-system energies. We present here a first calculation ... [Phys. Rev. C 85, 024306 ] published .
Phase transitions in two-dimensional Z(N) vector models for N>4
O. Borisenko, V. Chelnokov, G. Cortese, R. Fiore, M. Gravina et al.
We investigate both analytically and numerically the renormalization group equations in two-dimensional (2D) Z(N) vector models. The position of the critical points of the two phase transitions for N>4 is established and the critical index nu is computed. For N=7 and 17 the critical points are locat ... [Phys. Rev.

Ghost-gluon coupling, power corrections, and Lambda from lattice QCD with a dynamical charm
B. Blossier, Ph. Boucaud, M. Brinet, F. De Soto, X. Du et al.
This paper is a first report on the determination of Lambda from lattice simulations with 2+1+1 twisted-mass dynamical flavors via the computation of the ghost-gluon coupling renormalized in the MOM Taylor scheme. We show this approach allows a very good control of the lattice artefacts and confirm ... [Phys. Rev. D 85, 034503 ] published .
On flavor symmetry in lattice quantum chromodynamics
El Hassan Saidi
Using a well established method to engineer non-abelian symmetries in superstring compactifications, we study the link between the point splitting method of Creutz et al. [PoS: Lattice 2010, 078 (2010) and JHEP 041, 1012 (2010)] for implementing flavor symmetry in lattice QCD; and singularity theo ... [J. Math. Phys. 53, 022302 (2012)] published Thu Feb 9, 2012.

Optimal control of quantum superpositions in a bosonic Josephson junction
M. Lapert, G. Ferrini, and D. Sugny
We show how to optimally control the creation of quantum superpositions in a bosonic Josephson junction within the two-site Bose-Hubbard-model framework. Both geometric and purely numerical optimal-control approaches are used, the former providing a generalization of the proposal of Micheli et al. [ ... [Phys. Rev. A 85, 023611 ] published .
Resonant control of polar molecules in individual sites of an optical lattice
Thomas M. Hanna, Eite Tiesinga, William F. Mitchell, and Paul S. Julienne
We study the resonant control of two nonreactive polar molecules in an optical lattice site, focusing on the example of RbCs. Collisional control can be achieved by tuning bound states of the intermolecular dipolar potential by varying the applied electric field or trap frequency. We consider a wide ... [Phys. Rev.

A first-principles density functional theory study of the electronic structural and thermodynamic properties of MZrO and MCO (M = Na, K) and their capabilities for CO capture

Alkali metal zirconates could be used as solid sorbents for CO capture. The structural, electronic, and phonon properties of NaZrO, KZrO, NaCO, and KCO are investigated by combining the density functional theory with lattice phonon dynamics. The thermodynamics of CO absorption/desorption reactions o ... [J. Renewable Sustainable Energy 4, 013109 (2012)] published Wed Feb 8, 2012.
Rectification of Spatial Disorder
Jaegon Um, Hyunsuk Hong, Fabio Marchesoni, and Hyunggyu Park
We demonstrate that a large ensemble of noiseless globally coupled-pinned oscillators is capable of rectifying spatial disorder with spontaneous current activated through a dynamical phase transition mechanism, either of first or second order, depending on the profile of the pinning potential. In th ... [Phys. Rev. Lett. 108, 060601 ] published .
Equation of state of a quasiparticle model at finite chemical potential and quark star

Two-body Coulomb scattering and complex scaling

The two-body Coulomb scattering problem is solved using the standard complex-scaling method. The explicit enforcement of the scattering boundary condition is avoided. Splitting of the scattering wave function based on the Coulomb modified plane wave is considered. This decomposition leads to a three ... [Phys. Rev. A 85, 022702 ] published .

We study D meson resonances in hot, dense quark matter within the NambuJona-Lasinio model and its Polyakov-loop extension. We show that the mass splitting between D and D mesons is moderate, not in excess of 100 MeV. When the decay channel into quasifree quarks opens (Mott effect) at densities above ... [Phys. Rev.
