A first look at Landau-gauge propagators in G2 Yang-Mills theory
Axel Maas, Stefan Olejnik
G_2 Yang--Mills theory is an interesting laboratory to investigate non-perturbative effects. On one hand, no conventional quark confinement via a linearly rising potential is prese…
Symmetry-broken crystal structure of elemental boron at low temperature
M. Widom, M. Mihalkovic
The crystal structure of boron is unique among chemical elements, highly complex, and imperfectly known. Experimentalists report the beta-rhombohedral (black) form is stable over a…
Metal - Insulator Transition in 3D Quantum Percolation
Igor Travenec
We present the metal - insulator transition study of a quantum site percolation model on simple cubic lattice. Transfer matrix method is used to calculate transport properties - La…
Elliptic Flow in Central Collisions of Deformed Nuclei
Peter Filip
Non-trivial geometrical effects in relativistic central collisions of deformed nuclei are studied using a simple version of optical Glauber model. For very small impact parameters…
Photometric Analysis of Recently Discovered Eclipsing Binary GSC 00008-00901
S. Parimucha, T. Pribulla, M. Vaňko +2
Photometric analysis of light curves of newly discovered eclipsing binary GSC 0008-00901 is presented. The orbital period is improved to 0.28948(11) days. Photometric param…
On Fixed-multiplicity Corrections to Correlators
Peter Filip
Correction terms generated in the correlator analysis due to multiplicity-dependent observable mean are investigated. A procedure for subtraction of such terms from calculated corr…
Effects of hydrodynamic noise on the diffusion of polymers in dilute solutions
V. Lisy, J. Tothova, A. V. Zatovsky
The Rouse-Zimm equation for the position vectors of beads mapping the polymer is generalized by taking into account the viscous aftereffect and the hydrodynamic noise. For the nois…
Statistical mechanics of non-hamiltonian systems: Traffic flow
Anton Šurda
Statistical mechanics of a small system of cars on a single-lane road is developed. The system is not characterized by a Hamiltonian but by a conditional probability of a velocity…
Critical conductance of the chiral 2d random flux model
L. Schweitzer, P. Markoš
The two-terminal conductance of a random flux model defined on a square lattice is investigated numerically at the band center using a transfer matrix method. Due to the chiral sym…
Recycling of quantum information: Multiple observations of quantum systems
Peter Rapcan, John Calsamiglia, Ramon Munoz-Tapia +2
Given a finite number of copies of an unknown qubit state that have already been measured optimally, can one still extract any information about the original unknown state? We give…
Search for Pentaquarks in the Hadronic Decays of the Z Boson with the DELPHI Detector at LEP
The DELPHI Collaboration, J. Abdallah
The quark model does not exclude states composed of more than three quarks, like pentaquark systems. Controversial evidence for such states has been published in the last years, in…
Dimensional Reduction and the Yang-Mills Vacuum State in 2+1 Dimensions
J. Greensite, S. Olejnik
We propose an approximation to the ground state of Yang-Mills theory, quantized in temporal gauge and 2+1 dimensions, which satisfies the Yang-Mills Schrodinger equation in both th…
Generalized DMPK equation for strongly localized regime - numerical solution
J Brndiar, R. Derian, P. Markos
Generalized Dorokhov-Mello-Pereyra-Kumar (GDMPK) equation [K. A. Muttalib and J. R. Klauder, Phys. Rev. Lett. {\bf 82}, 4272 (1999)] has been proposed for the description of the el…
Sum-rules for electron energy-loss near-edge spectra
Ján Rusz, Olle Eriksson, Pavel Novák +1
We derive four sum-rule expressions for spectra measured in electron energy-loss near edge structure experiments. These sum-rules permit the determination spin and orbital magnetic…
Critical conductance of two-dimensional chiral systems with random magnetic flux
P. Markos, L. Schweitzer
The zero temperature transport properties of two-dimensional lattice systems with static random magnetic flux per plaquette and zero mean are investigated numerically. We study the…
Phase transitions in isolated strongly interacting systems
M. Veselsky
Thermodynamical properties of the nuclear matter at sub-saturation densities were investigated using a simple van der Waals-like equation of state with an additional term represent…
Correlations and sum rules in a half-space for a quantum two-dimensional one-component plasma
B. Jancovici, L. Samaj
This paper is the continuation of a previous one [L. {Š}amaj and B. Jancovici, 2007 {\it J. Stat. Mech.} P02002]; for a nearly classical quantum fluid in a half-space bounded by a…
Two- and three-point Green's functions in two-dimensional Landau-gauge Yang-Mills theory
Axel Maas
The ghost and gluon propagator and the ghost-gluon and three-gluon vertex of two-dimensional SU(2) Yang-Mills theory in (minimal) Landau gauge are studied using lattice gauge theor…
Inverse Geometric Approach to the Simulation of the Circular Growth. The Case of Multicellular Tumor Spheroids
Branislav Brutovsky, Denis Horvath, Vladimir Lisy
We demonstrate the power of the genetic algorithms to construct the cellular automata model simulating the growth of 2-dimensional close-to-circular clusters revealing the desired…
Energy density for chiral lattice fermions with chemical potential
Christof Gattringer, Ludovit Liptak
We study a recently proposed formulation of overlap fermions at finite density. In particular we compute the energy density as a function of the chemical potential and the temperat…
Wigner-Kirkwood expansion for semi-infinite quantum fluids
L. Samaj, B. Jancovici
For infinite (bulk) quantum fluids of particles interacting via pairwise sufficiently smooth interactions, the Wigner-Kirkwood formalism provides a semiclassical expansion of the B…
