Logistic dynamics of small populations with demographic stochasticity
Lucas M. Brugevin, Damián H. Zanette
We study an ecology-inspired model for a population of bounded size, whose dynamics is governed by random birth, death, and immigration events. Stochastic fluctuations in the numbe…
Dynamical phases transitions in periodically driven Bardeen-Cooper-Schrieffer systems
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro +2
We present a systematic study of the dynamical phase diagram of a periodically driven BCS system as a function of drive strength and frequency. Three different driving mechanism ar…
Multistability of globally coupled Duffing oscillators
Raúl I. Sosa, Damián H. Zanette
We analyze the collective dynamics of an ensemble of globally coupled, externally forced, identical mechanical oscillators with cubic nonlinearity. Focus is put on solutions where…
Lévy copulas: a probabilistic point of view
Ayi Ajavon
There is a one-to-one correspondence between Lévy copulas and proper copulas. The correspondence relies on a relationship between Lévy copulas sitting on and max-id…
Energy flow and dissipation in heterogeneous ensembles of coupled phase oscillators
Raúl I. Sosa, Damián H. Zanette
We present analytical expressions and numerical results for the rates of energy exchange between oscillators and with the environment in a heterogeneous ensemble of globally couple…
Emergent parametric resonances and time-crystal phases in driven BCS systems
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro +2
We study the out-of-equilibrium dynamics of a Bardeen-Cooper-Schrieffer condensate subject to a periodic drive. We demonstrate that the combined effect of drive and interactions re…
