The functional integral with unconditional Wiener measure for anharmonic oscillator
J. Bohacik, P. Presnajder
In this article we propose the calculation of the unconditional Wiener measure functional integral with a term of the fourth order in the exponent by an alternative method as in th…
Radiative corrections to muon decay in leading and next to leading approximation for electron spectrum
E. Bartos, E. A. Kuraev, M. Secansky
We have noted that the electron spectrum of muon decay in the leading logarithmic approximation calculated in two lowest orders of the perturbation theory in the paper of Berman (1…
First evidence for Casimir scaling in G(2) lattice gauge theory
L. Liptak, S. Olejnik
Potentials between static quarks and antiquarks from a few lowest representations were evaluated in numerical simulations of 4-dimensional pure G lattice gauge theory at variou…
Quantum Speed-up for Approximating Partition Functions
Pawel Wocjan, Chen-Fu Chiang, Anura Abeyesinghe +1
We achieve a quantum speed-up of fully polynomial randomized approximation schemes (FPRAS) for estimating partition functions that combine simulated annealing with the Monte-Carlo…
Penrose Matching Rules from Realistic Potentials in a Model System
Sejoon Lim, M. Mihalkovic, C. L. Henley
We exhibit a toy model of a binary decagonal Al-Co quasicrystal -- closely related to actual structures -- in which realistic pair potentials yield a ground state which appears to…
More on Gribov copies and propagators in Landau-gauge Yang-Mills theory
Axel Maas
Fixing a gauge in the non-perturbative domain of Yang-Mills theory is a non-trivial problem due to the presence of Gribov copies. In particular, there are different gauges in the n…
Casimir scaling in G(2) lattice gauge theory
L. Liptak, S. Olejnik
We computed potentials between static color sources from the six lowest representations of G(2) lattice gauge theory, in numerical simulations with the Wilson action on asymmetric…
Center Vortices and the Dirac Spectrum
Manfried Faber, Jeff Greensite, Urs M. Heller +2
We study correlations between center vortices and the low-lying eigenmodes of the Dirac operator, in both the overlap and asqtad formulations. In particular we address a puzzle rai…
Linear Covariant Gauges on the Lattice
Attilio Cucchieri, Axel Maas, Tereza Mendes
Linear covariant gauges, such as Feynman gauge, are very useful in perturbative calculations. Their nonperturbative formulation is, however, highly non-trivial. In particular, it i…
Three-point vertices in Landau-gauge Yang-Mills theory
Attilio Cucchieri, Axel Maas, Tereza Mendes
Vertices are of central importance for constructing QCD bound states out of the individual constituents of the theory, i.e. quarks and gluons. In particular, the determination of t…
Empirical oscillating potentials for alloys from ab-initio fits
M. Mihalkovič, C. L. Henley, M. Widom +1
By fitting to a database of ab-initio forces and energies, we can extract pair potentials for alloys, with a simple six-parameter analytic form including Friedel oscillations, whic…
Character of eigenstates of the 3D disordered Anderson Hamiltonian
J. Brndiar, P. Markos
We study numerically the character of electron eigenstates of the three dimensional disordered Anderson model. Analysis of the statistics of inverse participation ratio as well as…
and annihilation as calibration processes for high energy colliders
E. Bartos, S. Bakmaev, E. A. Kuraev +2
Born differential cross sections and the lowest-order radiative correction to them are obtained in the kinematics of large-angle final photons emission in high-energy electron-posi…
Statistical and dynamical aspects in the decay of hot neutron-rich nuclei
M. Veselsky, A. L. Keksis, G. A. Souliotis +6
The signal of isospin-asymmetric phase transition in the evolution of the chemical potential was observed for hot quasi-projectiles produced in the reactions 40,48Ca + 27Al confirm…
