Ultra-sensitive in-beam gamma-ray spectroscopy for nuclear astrophysics at LUNA
A. Caciolli, L. Agostino, D. Bemmerer +29
Ultra-sensitive in-beam gamma-ray spectroscopy studies for nuclear astrophysics are performed at the LUNA (Laboratory for Underground Nuclear Astrophysics) 400 kV accelerator, deep…
Self-sustained traversable wormholes in noncommutative geometry
Remo Garattini, Francisco S. N. Lobo
In this work, we find exact wormhole solutions in the context of noncommutative geometry, and further explore their physical properties and characteristics. The energy density of t…
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…
Microscopic linear response calculations based on the Skyrme functional plus the pairing contribution
Jun Li, Gianluca Colo', Jie Meng
A self-consistent Quasiparticle-Random-Phase-Approximation (QRPA) model which employs the canonical Hartree-Fock-Bogoliubov (HFB) basis and an energy-density functional with a Skyr…
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…
Spinor Dynamics of Quantum Accelerator Modes near Higher Order Resonances
L. Rebuzzini, I. Guarneri, R. Artuso
Quantum Accelerator Modes were discovered in experiments with Kicked Cold Atoms in the presence of gravity. They were shown to be tightly related to resonances of the Quantum Kicke…
Search for the Z(4430)^- at BABAR
The BABAR Collaboration, B. Aubert
We report the results of a search for decay to or in $B^{-,0}\to \jpsiπ^- K^{0,+}$ and $B^{-,0}\to \psitwos π^- K^{0,+}$ decays. The data were colle…
Single impurity operators at critical wrapping order in the beta-deformed N=4 SYM
Francesco Fiamberti, Alberto Santambrogio, Christoph Sieg +1
We study the spectrum of one single magnon in the superconformal beta-deformed N=4 SYM theory in the planar limit. We compute the anomalous dimensions of one-impurity operators O_{…
Steering Bose-Einstein condensates despite time symmetry
Dario Poletti, Giuliano Benenti, Giulio Casati +2
A Bose-Einstein condensate in an oscillating spatially asymmetric potential is shown to exhibit a directed current for unbiased initial conditions despite time symmetry. This pheno…
Black Holes as Lumps of Fluid
Marco M. Caldarelli, Oscar J. C. Dias, Roberto Emparan +1
The old suggestive observation that black holes often resemble lumps of fluid has recently been taken beyond the level of an analogy to a precise duality. We investigate aspects of…
Effect of Tensor Correlations on Gamow-Teller States in 90Zr and 208Pb
C. L. Bai, H. Sagawa, H. Q. Zhang +3
The tensor terms of the Skyrme effective interaction are included in the self-consistent Hartree-Fock plus Random Phase Approximation (HF+RPA) model. The Gamow-Teller (GT) strength…
Systematic thermal reduction of neutronization in core-collapse supernovae
A. F. Fantina, P. Donati, P. M. Pizzochero
We investigate to what extent the temperature dependence of the nuclear symmetry energy can affect the neutronization of the stellar core prior to neutrino trapping during gravitat…
Semiclassical model for a memory dephasing channel
A. D'Arrigo, G. Benenti, G. Falci
We study a dephasing channel with memory, described by a Hamiltonian model in which the system-environment interaction is described by a stochastic process. We propose a useful way…
A Quantum Fluid Description of the Free Electron Laser
R. Bonifacio, N. Piovella, G. R. M Robb +1
Using the Madelung transformation we show that in a quantum Free Electron Laser (QFEL) the beam obeys the equations of a quantum fluid in which the potential is the classical poten…
Exact sampling of corrugated surfaces
Sergio Caracciolo, Enrico Rinaldi, Andrea Sportiello
We discuss an algorithm for the exact sampling of vectors v in [0,1]^N satisfying a set of pairwise difference inequalities. Applications include the exact sampling of skew Young T…
Explicit characterization of the identity configuration in an Abelian Sandpile Model
Sergio Caracciolo, Guglielmo Paoletti, Andrea Sportiello
Since the work of Creutz, identifying the group identities for the Abelian Sandpile Model (ASM) on a given lattice is a puzzling issue: on rectangular portions of Z^2 complex quasi…
Master Space, Hilbert Series and Seiberg Duality
Davide Forcella, Amihay Hanany, Alberto Zaffaroni
We analyze the action of Toric (Seiberg) duality on the combined mesonic and baryonic moduli space of quiver gauge theories obtained from D3 branes at Calabi-Yau singularities. We…
Gaussian wave packets in phase space: The Fermi g_F function
Giuliano Benenti, Giuliano Strini
Any pure quantum state can be equivalently represented by means of its wave function psi(q) or of the Fermi function g_F(q,p), with q and p coordinates and conjugate momenta of the…
Massive Dirac particles on the background of charged de-Sitter black hole manifolds
F. Belgiorno, S. L. Cacciatori
We consider the behavior of massive Dirac fields on the background of a charged de-Sitter black hole. All black hole geometries are taken into account, including the Reissner-Nords…
Optimal purification of a generic n-qudit state
Giuliano Benenti, Giuliano Strini
We propose a quantum algorithm for the purification of a generic mixed state of a -qudit system by using an ancillary -qudit system. The algorithm is optimal in that (i)…
