Nucleon electromagnetic and axial form factors in point-form relativistic quantum mechanics
R. F. Wagenbrunn, S. Boffi, L. Ya. Glozman +3
Results for the proton and neutron electric and magnetic form factors as well as the nucleon axial form factor are presented for constituent quark models, based on either one-gluon…
Construction of extremal local positive operator-valued measures under symmetry
S. Virmani, M. B. Plenio
We study the local implementation of POVMs when we require only the faithful reproduction of the statistics of the measurement outcomes for all initial states. We first demonstrate…
The XMM-Newton view of the radio-quiet neutron star 1E 1207.4-5209
A. De Luca, S. Mereghetti, P. A. Caraveo +3
We have observed the radio-quiet X-ray pulsar 1E 1207.4-5209 with the high throughput EPIC cameras onboard XMM-Newton. The spectrum of this peculiar source is characterized by two…
Quantum Monte Carlo study of S=1/2 weakly-anisotropic antiferromagnets on the square lattice
Alessandro Cuccoli, Tommaso Roscilde, Valerio Tognetti +2
We study the finite-temperature behaviour of two-dimensional S=1/2 Heisenberg antiferromagnets with very weak easy-axis and easy-plane exchange anisotropies. By means of quantum Mo…
