Logistic and -logistic models in population dynamics: General analysis and exact results
Nicola Cufaro Petroni, Salvatore De Martino, Silvio De Siena
In the present paper we provide the closed form of the path-like solutions for the logistic and -logistic stochastic differential equations, along with the exact expressions of…
Scaling of the Rényi entropies in gapped quantum spin systems: Entanglement-driven order beyond symmetry breaking
S. M. Giampaolo, S. Montangero, F. Dell'Anno +2
We investigate the scaling of the Rényi -entropies in one-dimensional gapped quantum spin models. We show that the block entropies with violate the area law monotonicity…
Stochastic origin of Gompertzian growths
E. De Lauro, S. De Martino, S. De Siena +1
This work faces the problem of the origin of the logarithmic character of the Gompertzian growth. We show that the macroscopic, deterministic Gompertz equation describes the evolut…
Hierarchical Gompertzian growth maps with application in astrophysics
S. De Martino, S. De Siena
The Gompertz model describes the growth in time of the size of significant quantities associated to a large number of systems, taking into account nonlinearity features by a linear…
Optimal estimation of losses at the ultimate quantum limit with non-Gaussian states
G. Adesso, F. Dell'Anno, S. De Siena +2
We address the estimation of the loss parameter of a bosonic channel probed by arbitrary signals. Unlike the optimal Gaussian probes, which can attain the ultimate bound on precisi…
Hierarchies of Geometric Entanglement
M. Blasone, F. Dell'Anno, S. De Siena +1
We introduce a class of generalized geometric measures of entanglement. For pure quantum states of elementary subsystems, they are defined as the distances from the sets of …
