Comment on "Negative specific heat for a cluster of 147 Sodium atoms" by Schmidt et al
C. Tsallis, B. J. C. Cabral, A. Rapisarda +1
Schmidt et al (Phys Rev Lett 86, 1191 (2001)) observe and analyze a negative specific heat in Na clusters. The analysis is done within the framework of Boltzmann-Gibbs equilibrium…
Frontier between separability and quantum entanglement in a many spin system
F. C. Alcaraz, C. Tsallis
We discuss the critical point separating the quantum entangled and separable states in two series of N spins S in the simple mixed state characterized by the matrix operator…
Nonstandard mixing in the standard map
Fulvio Baldovin, Constantino Tsallis, Bruno Schulze
The standard map is a paradigmatic one-parameter (noted ) two-dimensional conservative map which displays both chaotic and regular regions. This map becomes integrable for …
Asymmetric unimodal maps at the edge of chaos
U. Tirnakli, C. Tsallis, M. L. Lyra
We numerically investigate the sensitivity to initial conditions of asymmetric unimodal maps ( correspond to and respectively, $z_…
Negative specific heat in a Lennard-Jones-like gas with long-range interactions
Ernesto P. Borges, Constantino Tsallis
We study, through molecular dynamics, a conservative two-dimensional Lennard-Jones-like gas (with attractive potential ). We consider the effect of the range index…
Risk aversion in economic transactions
C. Anteneodo, C. Tsallis, A. S. Martinez
Most people are risk-averse (risk-seeking) when they expect to gain (lose). Based on a generalization of ``expected utility theory'' which takes this into account, we introduce an…
Fingerprints of nonextensive thermodynamics in a long-range Hamiltonian system
V. Latora, A. Rapisarda, C. Tsallis
We study the dynamics of a Hamiltonian system of N classical spins with infinite-range interaction. We present numerical results which confirm the existence of metaequilibrium Quas…
Non-Gaussian equilibrium in a long-range Hamiltonian system
V. Latora, A. Rapisarda, C. Tsallis
We study the dynamics of a system of N classical spins with infinite-range interaction. We show that, when the thermodynamic limit is taken before the infinite-time limit, the syst…
Spin wave specific heat in quasiperiodic Fibonacci structures
C. G. Bezerra, E. L. Albuquerque, A. M. Mariz +2
The energy spectra of a variety of collective modes on quasiperiodic structures exhibit a complex fractal profile. Among the modes that have attracted particular attention in this…
