Compactification near and on the light front
A. Harindranath, L. Martinovic, J. P. Vary
We address problems associated with compactification near and on the light front. In perturbative scalar field theory we illustrate and clarify the relationships among three approa…
Incommensurate structures studied by a modified Density Matrix Renormalization Group Method
Andrej Gendiar, Anton Surda
A modified density matrix renormalization group (DMRG) method is introduced and applied to classical two-dimensional models: the anisotropic triangular nearest- neighbor Ising (ATN…
First Evidence for Center Dominance in SU(3) Lattice Gauge Theory
M. Faber, J. Greensite, S. Olejnik
The dominance of center degrees of freedom is observed in SU(3) lattice gauge theory in maximal center gauge. The full asymptotic string tension is reproduced, after center project…
The Vortex-Finding Property of Maximal Center (and Other) Gauges
M. Faber, J. Greensite, S. Olejnik +1
We argue that the ``vortex-finding'' property of maximal center gauge, i.e. the ability of this gauge to locate center vortices inserted by hand on any given lattice, is the key to…
Kinks in the discrete sine-Gordon model with Kac-Baker long-range interactions
Serge F. Mingaleev, Yuri B. Gaididei, Eva Majernikova +1
We study effects of Kac-Baker long-range dispersive interaction (LRI) between particles on kink properties in the discrete sine-Gordon model. We show that the kink width increases…
The Structure of Projected Center Vortices at Zero and Finite Temperature
R. Bertle, M. Faber, J. Greensite +1
We investigate the structure of center projected vortices of SU(2) lattice gauge theory at zero and finite temperature. At zero temperature we find, in agreement with the area law…
Another Derivation of a Sum Rule for the Two-Dimensional Two-Component Plasma
B. Jancovici, P. Kalinay, L. Samaj
In a two-dimensional two-component plasma, the second moment of the number density correlation function has the simple value , where is the dimensionl…
Some Insights into the Method of Center Projection
M. Faber, J. Greensite, S. Olejnik +1
We present several new results which pertain to the successes of center projection in maximal center gauge (MCG). In particular, we show why any center vortex, inserted "by hand" i…
Metal-insulator transition in three dimensional Anderson model: universal scaling of higher Lyapunov exponents
P. Markos
Numerical studies of the Anderson transition are based on the finite-size scaling analysis of the smallest positive Lyapunov exponent. We prove numerically that the same scaling ho…
Centrality Dependence of Directed and Elliptic Flow at the SPS
NA49 Collaboration, A. M. Poskanzer, S. A. Voloshin
New data with a minimum bias trigger for 158 GeV/nucleon Pb + Pb have been analyzed. Directed and elliptic flow as a function of rapidity of the particles and centrality of the col…
Quantum synthesis of arbitrary unitary operators
B. Hladky, G. Drobny, V. Buzek
Nature provides us with a restricted set of microscopic interactions. The question is whether we can synthesize out of these fundamental interactions an arbitrary unitary operator.…
The Structure of Projected Center Vortices in Lattice Gauge Theory
R. Bertle, M. Faber, J. Greensite +1
We investigate the structure of center vortices in maximal center gauge of SU(2) lattice gauge theory at zero and finite temperature. In center projection the vortices (called P-vo…
Quantum simulations of optical systems
M. Havukainen, G. Drobny, S. Stenholm +1
We show how two level atoms can be used to build microscopic models for mirrors and beamsplitters. The mirrors can have arbitrary shape allowing closed cavities to be built. It is…
Entangling Atoms in Photonic Crystals
Martin Konopka, Vladimir Buzek
We propose a method for entangling a system of two-level atoms in photonic crystals. The atoms are assumed to move in void regions of a photonic crystal. The interaction between th…
Probability distribution of the conductance at the mobility edge
Peter Markos
Distribution of the conductance P(g) at the critical point of the metal-insulator transition is presented for three and four dimensional orthogonal systems. The form of the distrib…
Optimal Manipulations with Qubits: Universal NOT Gate
V. Buzek, M. Hillery, R. Werner
It is not a problem to complement a classical bit, i.e. to change the value of a bit, a 0 to a 1 and vice versa. This is accomplished by a NOT gate. Complementing a qubit in an unk…
