Correlated Gaussian systems exhibiting additive power-law entropies
C. Vignat, A. Plastino, A. R. Plastino
We show, on purely statistical grounds and without appeal to any physical model, that a power-law entropy , with , can be {\it extensive}. More specifically, if the…
Krein's Formula And Heat-Kernel Expansion For Some Differential Operators With A Regular Singularity
H. Falomir, P. A. G. Pisani
We get a generalization of Krein's formula -which relates the resolvents of different selfadjoint extensions of a differential operator with regular coefficients- to the non-regula…
Pairing Correlations in Odd-Mass Carbon Isotopes and Effect of Pauli Principle in Particle-Core Coupling in 13C and 11Be
A. R. Samana, T. Tarutina, F. Krmpotić +2
We present an exploratory study of structure of 13C, 15C, 17C and 19C, showing that the simple one-quasiparticle projected BCS (PBCS) model is capable to account for several import…
Phase diagram of neutral quark matter in nonlocal chiral quark models
D. Gomez Dumm, D. B. Blaschke, A. G. Grunfeld +1
We consider the phase diagram of two-flavor quark matter under neutron star constraints for two nonlocal, covariant quark models within the mean field approximation. In the first c…
Comparative study of an Eden model for the irreversible growth of spins and the equilibrium Ising model
Julián Candia, Ezequiel V. Albano
The Magnetic Eden Model (MEM) with ferromagnetic interactions between nearest-neighbor spins is studied in dimensional rectangular geometries for . In the MEM, mag…
Globular cluster systems in low-luminosity early-type galaxies near the Fornax Cluster centre
Lilia P. Bassino, Tom Richtler, Boris Dirsch
We present a photometric study of the globular cluster systems of the Fornax cluster galaxies NGC 1374, NGC 1379, and NGC 1387. The data consists of images from the wide-field MOSA…
