The June 2008 flare of Markarian 421 from optical to TeV energies
The Agile Collaboration, Webt Collaboration, Magic Collaboration +2
We present optical, X-ray, high energy ( GeV) and very high energy ( GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken betwee…
The isolated neutron star candidate 2XMM J104608.7-594306
A. M. Pires, C. Motch, R. Turolla +2
Over the last decade, X-ray observations unveiled the existence of several classes of isolated neutron stars (INSs) which are radio-quiet or exhibit radio emission with properties…
Particle decays and stability on the de Sitter universe
Jacques Bros, Henri Epstein, Ugo Moschella
We study particle decay in de Sitter space-time as given by first order perturbation theory in a Lagrangian interacting quantum field theory. We study in detail the adiabatic limit…
Theory of Tunneling Spectroscopy in a Mn Single-Electron Transistor by Density-Functional Theory Methods
L. Michalak, C. M. Canali, M. R. Pederson +2
We consider tunneling transport through a Mn molecular magnet using spin density functional theory. A tractable methodology for constructing many-body wavefunctions from Koh…
Relaxation due to random collisions with a many-qudit environment
Giuseppe Gennaro, Giuliano Benenti, G. Massimo Palma
We analyze the dynamics of a system qudit of dimension mu sequentially interacting with the nu-dimensional qudits of a chain playing the ore of an environment. Each pairwise collis…
The quantum-classical transition in thermally seeded parametric downconversion
Ivo P Degiovanni, Marco Genovese, Valentina Schettini +3
We address the pair of conjugated field modes obtained from parametric-downconversion as a convenient system to analyze the quantum-classical transition in the continuous variable…
