Measurement of the inclusive isolated-photon cross section in pp collisions at s $$ \sqrt{s} $$ = 13 TeV using 36 fb −1 of ATLAS data

open access: yesJournal of High Energy Physics, 2019
The differential cross section for isolated-photon production in pp collisions is measured at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC using an integrated luminosity of 36.1 fb −1.

Interferometric distillation and determination of unknown two-qubit entanglement

open access: yes, 2010
We propose a scheme for both distilling and quantifying entanglement, applicable to individual copies of an arbitrary unknown two-qubit state. It is realized in a usual two-qubit interferometry with local filtering.

Reflection Symmetries for Multiqubit Density Operators

open access: yes, 2005
For multiqubit density operators in a suitable tensorial basis, we show that a number of nonunitary operations used in the detection and synthesis of entanglement are classifiable as reflection symmetries, i.e., orientation changing rotations.

Bi-abundance ionization structure of the Wolf-Rayet planetary nebula PB 8

open access: yes, 2018
The planetary nebula (PN) PB 8 around a [WN/WC]-hybrid central star is one of PNe with moderate abundance discrepancy factors (ADFs ~ 2-3), which could be an indication of a tiny fraction of metal-rich inclusions embedded in the nebula (bi-abundance). In

Measurement of $$W^{\pm }$$ W± -boson and Z-boson production cross-sections in pp collisions at $$\sqrt{s}=2.76$$ s=2.76  TeV with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The production cross-sections for $$W^{\pm }$$ W± and Z bosons are measured using ATLAS data corresponding to an integrated luminosity of 4.0 pb$$^{-1}$$ -1 collected at a centre-of-mass energy $$\sqrt{s}=2.76$$ s=2.76  TeV.

Decoherence and multipartite entanglement of non-inertial observers

open access: yes, 2012
Decoherence effect on multipartite entanglement in non-inertial frames is investigated. GHZ state is considered to be shared between the partners with one partner in inertial frame whereas the other two in accelerated frames. One-tangle and {\pi}-tangles

Velocity and density profiles of granular flow in channels using lattice gas automaton

open access: yes, 1997
We have performed two-dimensional lattice-gas-automaton simulations of granular flow between two parallel planes. We find that the velocity profiles have non-parabolic distributions while simultaneously the density profiles are non-uniform.

Electronic transport through a quantum dot network

open access: yes, 2004
The conductance through a finite quantum dot network is studied as a function of inter-dot coupling. As the coupling is reduced, the system undergoes a transition from the antidot regime to the tight binding limit, where Coulomb resonances with on ...

The sandpile group of a trinity and a canonical definition for the planar Bernardi action

open access: yes, 2020
Baker and Wang define the so-called Bernardi action of the sandpile group of a ribbon graph on the set of its spanning trees. This potentially depends on a fixed vertex of the graph but it is independent of the base vertex if and only if the ribbon ...
