Charge and Current Sum Rules in Quantum Media Coupled to Radiation II
Ladislav Samaj, Bernard Jancovici
This paper is a continuation of the previous study [Šamaj, L.: J. Stat. Phys. {\bf 137}, 1-17 (2009)], where a sequence of sum rules for the equilibrium charge and current density…
Properties of canonical fermion determinants with a fixed quark number
Julia Danzer, Christof Gattringer, Ludovit Liptak
Using a dimensional reduction formula for the lattice fermion determinant we study canonical determinants on quenched SU(3) gauge configurations. The canonical determinants decribe…
Vacuum structure and Casimir scaling in Yang-Mills theories
S. Olejnik
The vacuum of Yang-Mills theories can be imagined as a magnetically disordered medium with domain structure, with color magnetic flux in each domain quantized in units correspondin…
Gluon chains and the quark-antiquark potential
J. Greensite, S. Olejnik
The flux tube between a quark and an antiquark in Coulomb gauge is imagined in the gluon-chain model as a sequence of constituent gluons bound together by Coulombic nearest-neighbo…
Parameter differences of the charged and neutral rho-meson family
E. Bartos, S. Dubnicka, A. -Z. Dubnickova +2
New very precise KLOE data on $\m{e}^+\m{e}^-\toπ^+π^-$ obtained by radiative return method in Frascati are unified with corrected CMD-2 and SND Novosibirsk $\m{e}^+\m{e}^-\toπ^+π^…
Remarkable suppression of the contribution error into muon
E. Bartos, S. Dubnicka, A. -Z. Dubnickova +1
We use the unitary and analytic model of the pion electromagnetic form factor in order to evaluate in the lowest order the contribution into the muon magn…
Fast Universal Quantum Computation with Railroad-switch Local Hamiltonians
Daniel Nagaj
We present two universal models of quantum computation with a time-independent, frustration-free Hamiltonian. The first construction uses 3-local (qubit) projectors, and the second…
Theory of anisotropic exchange in laterally coupled quantum dots
Fabio Baruffa, Peter Stano, Jaroslav Fabian
The effects of spin-orbit coupling on the two-electron spectra in lateral coupled quantum dots are investigated analytically and numerically. It is demonstrated that in the absence…
A study of the sign problem for lattice QCD with chemical potential
Julia Danzer, Christof Gattringer, Ludovit Liptak +1
We study the expectation value of the phase of the fermion determinant for Wilson lattice fermions with chemical potential. We use quenched SU(3) ensembles and implement a recently…
Efficient compression of quantum information
Martin Plesch, Vladimir Buzek
We propose a scheme for an exact efficient transformation of a tensor product state of many identically prepared qubits into a state of a logarithmically small number of qubits. Us…
The elastic electron-deuteron scattering beyond one-photon exchange
A. P. Kobushkin, Ya. D. Krivenko-Emetov, S. Dubnicka
We discuss the elastic ed scattering beyond Born approximation. It is shown that the reaction amplitude contains six generalized form factors, but only three linearly independent c…
Canonical fermion determinants in lattice QCD - Numerical evaluation and properties
Erek Bilgici, Julia Danzer, Christof Gattringer +2
We analyze canonical fermion determinants, i.e., fermion determinants projected to a fixed quark number q. The canonical determinants are computed using a dimensional reduction for…
Unambiguous comparison of quantum measurements
Mario Ziman, Teiko Heinosaari, Michal Sedlak
The goal of comparison is to reveal the difference of compared objects as fast and reliably as possible. In this paper we formulate and investigate the unambiguous comparison of un…
Coexistence of quantum operations
Teiko Heinosaari, Daniel Reitzner, Peter Stano +1
Quantum operations are used to describe the observed probability distributions and conditional states of the measured system. In this paper, we address the problem of their joint m…
Fast Amplification of QMA
Daniel Nagaj, Pawel Wocjan, Yong Zhang
Given a verifier circuit for a problem in QMA, we show how to exponentially amplify the gap between its acceptance probabilities in the `yes' and `no' cases, with a method that is…
Quantum Machines
Mark Hillery, Vladimir Buzek
We discuss quantum information processing machines. We start with single purpose machines that either redistribute quantum information or identify quantum states. We then move on t…
The High-Acceptance Dielectron Spectrometer HADES
The HADES Collaboration, G. Agakishiev, A. Balanda +110
HADES is a versatile magnetic spectrometer aimed at studying dielectron production in pion, proton and heavy-ion induced collisions. Its main features include a ring imaging gas Ch…
Efficient Circuits for Quantum Walks
Chen-Fu Chiang, Daniel Nagaj, Pawel Wocjan
We present an efficient general method for realizing a quantum walk operator corresponding to an arbitrary sparse classical random walk. Our approach is based on Grover and Rudolph…
Constituent Gluon Content of the Static Quark-Antiquark State in Coulomb Gauge
J. Greensite, S. Olejnik
Motivated by the gluon-chain model of flux tube formation, we compute and diagonalize the transfer matrix in lattice SU(2) gauge theory for states containing heavy static quark-ant…
