Deformed Boson Condensate as a Model of Dark Matter
Mahnaz Maleki, Hosein Mohammadzadeh, Zahra Ebadi +1
We consider the condensate of -deformed bosons as a model of dark matter. Our observations demonstrate that for all values, the system condenses below a -dependent critic…
Avalanches on the Complex Network of Rigan Earthquake, Virtual Seismometer Technique, Criticality and Seismic Cycle
M. N. Najafi, M. Rahimi-Majd, T. Shirzad
We base our study on the statistical analysis of the Rigan earthquake 2010 December 20, which consists of estimating the earthquake network by means of virtual seismometer techniqu…
Formation probabilities and statistics of observables as defect problems in the free fermions and the quantum spin chains
M. N. Najafi, M. A. Rajabpour
We show that the computation of formation probabilities (FP) in the configuration basis and the full counting statistics (FCS) of observables in the quadratic fermionic Hamiltonian…
Geometry-induced non-equilibrium phase transition in sandpiles
M. N. Najafi, J. Cheraghalizadeh, M. Lukovic +1
We study the sandpile model on three-dimensional spanning Ising clusters with the temperature treated as the control parameter. By analyzing the three dimensional avalanches an…
Stationarity of the detrended price return in stock markets
Karina Arias-Calluari, Morteza. N. Najafi, Michael S. Harré +1
This paper proposes a governing equation for stock market indexes that accounts for non-stationary effects. This is a linear Fokker-Planck equation (FPE) that describes the time ev…
Q-Gaussian diffusion in stock markets
Alonso-Marroquin Fernando, Arias-Calluari Karina, Harre Michael +2
We analyze the Standard & Poor's 500 stock market index from the last 22 years. The probability density function of price returns exhibits two well-distinguished regimes with self-…
