Two-Dimensional Tensor Product Variational Formulation
Tomotoshi Nishino, Yasuhiro Hieida, Kouichi Okunishi +3
We propose a numerical self-consistent method for 3D classical lattice models, which optimizes the variational state written as two-dimensional product of tensors. The variational…
Entanglement of coherent states and decoherence
Radim Filip, Jaroslav Rehacek, Miloslav Dusek
A possibility to produce entangled superpositions of strong coherent states is discussed. A recent proposal by Howell and Yazell [Phys. Rev. A 62, 012102 (2000)] of a device which…
Center vortices in MCG - finite-size and gauge-copy effects
Roman Bertle, Manfried Faber, Jeff Greensite +1
In SU(2) lattice gauge theory in maximal center gauge, we investigate the dependence of center-projected Creutz ratios and the vortex density on lattice size and the number of gaug…
Nucleon number dependence of the onset of anomalous J/psi suppression and the dynamics of nuclear collisions
Anna Nogova, Neva Pisutova, Jan Pisut
We point out that data on the onset of anomalous J/psi suppression as a function of nucleon numbers A and B could provide information on the dynamics of nuclear interactions. In pa…
Dimension dependence of the conductance distribution in the non-metallic regimes
Peter Markos
We study numerically the form of the conductance distribution in the non-metallic regime for (1) weakly disordered systems which become insulating due to increase of the system len…
Electronic transport in strongly anisotropic disordered systems: model for the random matrix theory with non-integer beta
Peter Markos
We study numerically an electronic transport in strongly anisotropic weakly disorderd two-dimensional systems. We find that the conductance distribution is gaussian but the conduct…
Light-Front Aspects of Chiral Symmetry
L. Martinovic, J. P. Vary
Spontaneous chiral symmetry breaking and axial anomaly are studied in the light-front formulation. The existence of multiple vacua and a Nambu-Goldstone boson, both related to dyna…
Existence of the -meson below 1 GeV and glueball
Yu. S. Surovtsev, D. Krupa, M. Nagy
On the basis of a simultaneous description of the isoscalar s-wave channel of the scattering (from the threshold up to 1.9 GeV) and of the process (from the t…
Super Chern Simons Theory and Flat Super Connections on a Torus
A. Mikovic, R. Picken
We study the moduli space of a super Chern-Simons theory on a manifold with the topology , where is a compact surface. The moduli space is that of flat super c…
P-Vortices, Gauge Copies, and Lattice Size
R. Bertle, M. Faber, J. Greensite +1
We study the dependence of the center-projected string tension on both the lattice size, and the number of gauge copies used for maximal center gauge fixing. We show that a recent…
Entangled webs: Tight bound for symmetric sharing of entanglement
Masato Koashi, Vladimir Buzek, Nobuyuki Imoto
Quantum entanglement cannot be unlimitedly shared among arbitrary number of qubits. Larger the number of entangled pairs in an N-qubit system, smaller the degree of bi-partite enta…
Scalar Mesons in a Chiral Quark Model with Glueball
D. Ebert, M. Nagy, M. K. Volkov +1
Ground-state scalar isoscalar mesons and a scalar glueball are described in a U(3)xU(3) chiral quark model of the Nambu--Jona-Lasinio (NJL) type with 't Hooft interaction. The latt…
The commensurate-disordered phase transition in 2D classical ATNNI model studied by DMRG
A. Gendiar, A. Surda
The classical two-dimensional anisotropic triangular nearest-neighbor Ising (ATNNI) model is studied by the density matrix renormalization group (DMRG) technique when periodic boun…
Fermionic Zero Modes and Spontaneous Symmetry Breaking on the Light Front
L. Martinovic, J. P. Vary
Spontaneous symmetry breaking is studied within a simple version of the light-front sigma model with fermions. Its vacuum structure is derived by an implementation of global symmet…
Recycling of quantum information: Multiple observations of quantum clocks
Vladimir Buzek, Peter L. Knight, Nobuyuki Imoto
How much information about the original state preparation can be extracted from a quantum system which already has been measured? That is, how many independent (non-communicating)…
Optimal manipulations with qubits: Universal quantum entanglers
Vladimir Buzek, Mark Hillery
We analyze various scenarios for entangling two initially unentangled qubits. In particular, we propose an optimal universal entangler which entangles a qubit in unknown state $|Ψ>…
What are the Confining Field Configurations of Strong-Coupling Lattice Gauge Theory?
M. Faber, J. Greensite, S. Olejnik
Starting from the strong-coupling SU(2) Wilson action in D=3 dimensions, we derive an effective, semi-local action on a lattice of spacing L times the spacing of the original latti…
Localization Transition in Multilayered Disordered Systems
S. N. Evangelou, Shi-Jie Xiong, P. Markov +1
The Anderson delocalization-localization transition is studied in multilayered systems with randomly placed interlayer bonds of density and strength . In the absence of diag…
Scalar Mesons and Glueballs in a Chiral U(3)xU(3) Quark Model with 't Hooft Interaction
M. Nagy, M. K. Volkov, V. L. Yudichev
In a U(3)x U(3) quark chiral model of the Nambu-Jona-Lasinio type with the 't Hooft interaction, the ground scalar isoscalar mesons and a scalar glueball are described. The gluebal…
The Density Matrix Renormalization Group technique with periodic boundary conditions
Andrej Gendiar, Anton Surda
The Density Matrix Renormalization Group (DMRG) method with periodic boundary conditions is introduced for two dimensional classical spin models. It is shown that this method is mo…
Thermodynamic Properties of the Two-Dimensional Two-Component Plasma
L. Šamaj, I. Travěnec
The model under consideration is a two-dimensional two-component plasma, stable against collapse for the dimensionless coupling constant . The combination of a technique of re…
Kink in a periodically modulated disordered system
Eva Majernikova, Jaroslav Riedel, Boris A. Malomed
We consider a dc-driven damped sine-Gordon model with a small nonlinear spatial-disorder term, onto which a sinusoidal modulation is superimposed. It describes, e.g., a weakly diso…
