Non-Boltzmann Equilibrium Probability Densities for Non-Linear Lévy Oscillator

A. Chechkin, V. Gonchar, R. Gorenflo +2

We study, both analytically and by numerical modeling the equilibrium probability density function for an non-linear Lévy oscillator with the Lévy index α, 1 \leq α\leq 2, and the…

Quantum shock waves in the Heisenberg XY model

Vladislav Popkov, Mario Salerno

We show the existence of quantum states of the Heisenberg XY chain which closely follow the motion of the corresponding semi-classical ones, and whose evolution resemble the propag…

What can nuclear collisions teach us about the boiling of water or the formation of multi-star systems ?

D. H. E. Gross

Phase transitions in nuclei, small atomic clusters and self-gravitating systems demand the extension of thermo-statistics to ``Small'' systems. The main obstacle is the thermodynam…

Fractional calculus and continuous-time finance II: the waiting-time distribution

Francesco Mainardi, Marco Raberto, Rudolf Gorenflo +1

We complement the theory of tick-by-tick dynamics of financial markets based on a Continuous-Time Random Walk (CTRW) model recently proposed by Scalas et al., and we point out its…

Exact equqations and scaling relations for f-avalanche in the Bak-Sneppen evolution model

W. Li, X. Cai

Infinite hierarchy of exact equations are derived for the newly-observed f-avalanche in the Bak-Sneppen evolution model. By solving the first order exact equation, we found that th…

Effect of Thermal Undulations on the Bending Elasticity and Spontaneous Curvature of Fluid Membranes

H. A. Pinnow, W. Helfrich

We amplify previous arguments why mean curvature should be used as measure of integration in calculating the effective bending rigidity of fluid membranes subjected to a weak backg…

Micro-canonical Statistical Mechanics of some Non-Extensive Systems

D. H. E. Gross

Non-extensive systems do not allow to go to the thermodynamic limit. Therefore we have to reformulate statistical mechanics without invoking the thermodynamical limit. I.e. we have…

On Density-Matrix Spectra for Two-Dimensional Quantum Systems

M. C. Chung, Ingo Peschel

For a two-dimensional system of coupled oscillators, the spectra of reduced density matrices can be obtained analytically. This provides an example where the features of these quan…

Exactly solvable statistical model for two-way traffic

Vladislav Popkov, Ingo Peschel

We generalize a recently introduced traffic model, where the statistical weights are associated with whole trajectories, to the case of two-way flow. An interaction between the two…

Phase transitions in generalized chiral or Stiefel's models

D. Loison

We study the phase transition in generalized chiral or Stiefel's models using Monte Carlo simulations. These models are characterized by a breakdown of symmetry O(N)/O(N-P). We sho…

First and second order transition of frustrated Heisenberg spin systems

D. Loison, K. D. Schotte

Starting from the hypothesis of a second order transition we have studied modifications of the original Heisenberg antiferromagnet on a stacked triangular lattice (STA-model) by th…

First and second order transition in frustrated XY systems

D. Loison, K. D. Schotte

The nature of the phase transition for the XY stacked triangular antiferromagnet (STA) is a controversial subject at present. The field theoretical renormalization group (RG) in th…

Critical behavior of frustrated systems: Monte Carlo simulations versus Renormalization Group

D. Loison, A. I. Sokolov, B. Delamotte +3

We study the critical behavior of frustrated systems by means of Pade-Borel resummed three-loop renormalization-group expansions and numerical Monte Carlo simulations. Amazingly, f…
