The inelastic Takahashi hard-rod gas
Umberto Marini-Bettolo-Marconi, Maurizio Natali, Giulio Costantini +1
We study a one-dimensional fluid of hard-rods interacting each other via binary inelastic collisions and a short ranged square-well potential. Upon tuning the depth and the sign of…
Trapped fermions with density imbalance in the BEC limit
P. Pieri, G. C. Strinati
We analyze the effects of imbalancing the populations of two-component trapped fermions, in the BEC limit of the attractive interaction between different fermions. Starting from th…
Stochastic resonance effects in quantum channels
Garry Bowen, Stefano Mancini
We provide some examples of quantum channels where the addition of noise is able to enhance the information transmission rate. This may happen for both quantum and classical uses a…
Momentum diffusion for coupled atom-cavity oscillators
K. Murr, P. Maunz, P. W. H. Pinkse +4
It is shown that the momentum diffusion of free-space laser cooling has a natural correspondence in optical cavities when the internal state of the atom is treated as a harmonic os…
Geometric Entropies of Mixing (EOM)
B. H. Lavenda
Trigonometric and trigonometric-algebraic entropies are introduced. Regularity increases the entropy and the maximal entropy is shown to result when a regular -gon is inscribed…
Polarizations and differential calculus in affine spaces
Margherita Barile, Fiorella Barone, Wlodzimierz M. Tulczyjew
Within the framework of mappings between affine spaces, the notion of -th polarization of a function will lead to an intrinsic characterization of polynomial functions. We prove…
