Semiclassical Propagation of Wavepackets with Real and Complex Trajectories
M. A. M. de Aguiar, M. Baranger, L. Jaubert +2
We consider a semiclassical approximation for the time evolution of an originally gaussian wave packet in terms of complex trajectories. We also derive additional approximations re…
Semiclassical Approximations in Phase Space with Coherent States
M. Baranger, M. A. M. de Aguiar, F. Keck +2
We present a complete derivation of the semiclassical limit of the coherent state propagator in one dimension, starting from path integrals in phase space. We show that the arbitra…
Generalization of the Peres criterion for local realism through nonextensive entropy
Constantino Tsallis, Seth Lloyd, Michel Baranger
A bipartite spin-1/2 system having the probabilities of being in the Einstein-Podolsky-Rosen entangled state $\do…
Time evolution of thermodynamic entropy for conservative and dissipative chaotic maps
M. Baranger, V. Latora, A. Rapisarda
We consider several low--dimensional chaotic maps started in far-from-equilibrium initial conditions and we study the process of relaxation to equilibrium. In the case of conservat…
The rate of entropy increase at the edge of chaos
V. Latora, M. Baranger, A. Rapisarda +1
Under certain conditions, the rate of increase of the statistical entropy of a simple, fully chaotic, conservative system is known to be given by a single number, characteristic of…
Kolmogorov-Sinai entropy-rate vs. physical entropy
Vito Latora, Michel Baranger
This paper elucidates the connection between the KS entropy-rate kappa and the time evolution of the physical or statistical entropy S. For a large family of chaotic conservative d…
