Sensitivity, entropy, and escape rates at the onset of chaos
Miguel Angel Fuentes, Yuzuru Sato, Constantino Tsallis
We analytically link three properties of nonlinear dynamical systems, namely sensitivity to initial conditions, entropy production, and escape rate, in -logistic maps for both p…
Quantum dissipative effects in moving imperfect mirrors: sidewise and normal motions
Cesar D. Fosco, Fernando C. Lombardo, Francisco D. Mazzitelli
We extend our previous work on the functional approach to the dynamical Casimir effect, to compute dissipative effects due to the relative motion of two flat, parallel, imperfect m…
SIR epidemics in monogamous populations with recombination
Damián H. Zanette
We study the propagation of an SIR (susceptible-infectious-recovered) disease over an agent population which, at any instant, is fully divided into couples of agents. Couples are o…
Scanning tunneling microscopy of adsorbed molecules on metalic surfaces for nearly localized atomic states
M. Romero, A. A. Aligia
We consider a Hubbard-Anderson model which describes localized orbitals in five different sites hybridized both among themselves and with a continuum of extended states. A square p…
Towards a derivation of holographic entanglement entropy
Horacio Casini, Marina Huerta, Robert C. Myers
We provide a derivation of holographic entanglement entropy for spherical entangling surfaces. Our construction relies on conformally mapping the boundary CFT to a hyperbolic geome…
Survival probability and first-passage-time statistics of a Wiener process driven by an exponential time-dependent drift
Eugenio Urdapilleta
The survival probability and the first-passage-time statistics are important quantities in different fields. The Wiener process is the simplest stochastic processwith continuous va…
