Small x divergences in a heavy quark-antiquark state
Martina Brisudova
With the current state of similarity renormalisation group approach to light-front QCD, it is possible to address with a degree of generality the issue of light-cone zero modes. We…
Effects of atomic interactions in two component submonolayer growth
Miroslav Kotrla, Joachim Krug
We discuss effects of the different chemical bondings on the island morphology and on the island density scaling in two-component submonolayer growth. Different regimes depending o…
Effects of adsorbates on submonolayer growth
Miroslav Kotrla, Joachim Krug, Pavel Smilauer
The effects of adsorbates on nucleation and growth of two-dimensional islands is investigated by kinetic Monte Carlo simulations and rate equation theory. The variation of island m…
Strange Vector Form Factor of Kaons
S. Dubnicka, A. Z. Dubnickova
Starting from the - mixing, further assuming the coupling of the quark-current of some flavour to be of universal strenth exclusively to the component of vector-meson wave fu…
Center Dominance Recovered: Direct Laplacian Center Gauge
M. Faber, J. Greensite, S. Olejnik
We introduce a variation of direct maximal center gauge fixing: the "direct Laplacian" center gauge. The new procedure consists of first fixing to the Laplacian adjoint Landau gaug…
Dynamics of open quantum systems initially entangled with environment: Beyond the Kraus representation
Peter Stelmachovic, Vladimir Buzek
We present a general analysis of the role of initial correlations between the open system and an environment on quantum dynamics of the open system.
Universality of the critical conductance distribution in various dimensions
Igor Travenec, Peter Markos
We study numerically the metal - insulator transition in the Anderson model on various lattices with dimension (bifractals and Euclidian lattices). The critical expon…
Discrimination of the Bell states of qudits by means of linear optics
Miloslav Dusek
The question of the discrimination of the Bell states of two qudits (i.e., d-dimensional quantum systems) by means of passive linear optical elements and conditional measurements i…
Wigner-function description of quantum teleportation in arbitrary dimensions and continuous limit
M. Koniorczyk, V. Buzek, J. Janszky
We present a unified approach to quantum teleportation in arbitrary dimensions based on the Wigner-function formalism. This approach provides us with a clear picture of all manipul…
Soft versus Hard Dynamics for Field-driven Solid-on-Solid Interfaces
Per Arne Rikvold, Miroslav Kolesik
Analytical arguments and dynamic Monte Carlo simulations show that the microstructure of field-driven Solid-on-Solid interfaces depends strongly on the dynamics. For nonconservativ…
Entanglement by a beam splitter: nonclassicality as a prerequisite for entanglement
M. S. Kim, W. Son, V. Bu{ž}ek +1
A beam splitter is a simple, readily available device which can act to entangle the output optical fields. We show that a necessary condition for the fields at the output of the be…
Direct Laplacian Center Gauge
M. Faber, J. Greensite, S. Olejnik
We introduce a variation of direct maximal center gauge fixing: the ``direct Laplacian'' center gauge. The new procedure overcomes certain shortcomings of maximal center gauge, ass…
Conductance fluctuations and boundary conditions
Marc Ruehlaender, Peter Markos, C. M. Soukoulis
The conductance fluctuations for various types for two-- and three--dimensional disordered systems with hard wall and periodic boundary conditions are studied, all the way from the…
Perturbative S-matrix in discretized light cone quantization of two-dimensional ϕ^4 theory
A. Harindranath, L. Martinovic, J. P. Vary
We study the S-matrix of two-dimensional λϕ^4 theory in Discretized Light Cone Quantization and show how the correct continuum limit is reached for various processes in lowest orde…

Third QED order hadronic light-by-light (LBL) contributions to the anomalous magnetic moment of the muon from the pole terms of scalar , an…
The Inverse Problem: Extracting Time-Like from Space-Like Data
R. Baldini, E. Pasqualucci, S. Dubnička +3
A practical strategy is presented and successfully implemented to determine form factors in the time-like but unphysical (below threshold) region using dispersion relations, in a m…
Density Correlations in the Two-Dimensional Coulomb Gas
L. Šamaj, B. Jancovici
We consider a two-dimensional Coulomb gas of positive and negative pointlike unit charges interacting via a logarithmic potential. The density (rather than the charge) correlation…
Bell-inequality violation with "thermal" radiation
Radim Filip, Miloslav Dusek, Jaromir Fiurasek +1
The model of a quantum-optical device for a conditional preparation of entangled states from input mixed states is presented. It is demonstrated that even thermal or pseudo-thermal…
Adelic Path Integrals for Quadratic Lagrangians
G. S. Djordjevic, B. Dragovich, L. Nesic
Feynman's path integral in adelic quantum mechanics is considered. The propagator K(x'',t'';x',t') for one-dimensional adelic systems with quadratic Lagrangians is analytically eva…
Singlet states and the estimation of eigenstates and eigenvalues of an unknown Controlled-U gate
Mark Hillery, Vladimir Buzek
We consider several problems that involve finding the eigenvalues and generating the eigenstates of unknown unitary gates. We first examine Controlled-U gates that act on qubits, a…
Reconciling Conductance Fluctuations and the Scaling Theory of Localization
Keith Slevin, Peter Markoš, Tomi Ohtsuki
We reconcile the phenomenon of mesoscopic conductance fluctuations with the single parameter scaling theory of the Anderson transition. We calculate three averages of the conductan…
