Noncommutative Quantum Cosmology
C. Bastos, O. Bertolami, N. Dias +1
One presents a phase-space noncommutative extension of Quantum Cosmology in the context of a Kantowski-Sachs (KS) minisuperspace model. We obtain the Wheeler-DeWitt (WDW) equation…
Spectroscopy of the unbound: One-neutron knockout reaction of Be
R. Crespo, A. Deltuva, M. Rodríguez-Gallardo +2
Full Faddeev-type calculations are performed for one-neutron knockout reaction of Be on proton target at 69 MeV/u incident energy. Inclusive transverse momentum distribution…
SIRS dynamics on random networks: simulations and analytical models
Ganna Rozhnova, Ana Nunes
The standard pair approximation equations (PA) for the Susceptible-Infective-Recovered-Susceptible (SIRS) model of infection spread on a network of homogeneous degree predict a…
The nonlinear N-membranes evolution problem
José Francisco Rodrigues, Lisa Santos, José Miguel Urbano
The parabolic N-membranes problem for the p-Laplacian and the complete order constraint on the components of the solution is studied in what concerns the approximation, the regular…
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…
The Narcowich-Wigner spectrum of a pure state
Nuno Costa Dias, Joao Nuno Prata
We completely characterize the Narcowich-Wigner spectrum of Wigner functions associated with pure states.
