Analytical expressions for energies, degeneracies and critical temperatures of the 2D square and 3D cubic Ising models

Dixon, J.M.; Tuszyński, J.A.; Carpenter, E.J. - In: Physica A: Statistical Mechanics and its Applications 349 (2005) 3, pp. 487-510

This paper revisits the fundamental statistical properties of the crucial model in critical phenomena i.e., the Ising model, guided by our knowledge of the energy values of the Ising Hamiltonian and aided by numerical estimation techniques. We have obtained exact energies in 2D and 3D and nearly...

Modelling free energy of a rigid protein in solid water: Comparison between rigid-body motions and harmonic oscillators

Yoshioki, Shuzo - In: Physica A: Statistical Mechanics and its Applications 331 (2004) 3, pp. 552-570

We test two methods to estimate a partition function of a system consisting of multi-atom molecules with intermolecular … (bovine pancreatic trypsin inhibitor) would be moving is limited, so by making a correction to a partition function of a rigid … oscillators. We obtain the partition function for the oscillators within a harmonic approximation. The function also depends on …

Critical temperature of Bose–Einstein condensation of a dilute Bose gas

Wang, Xian-Zhi - In: Physica A: Statistical Mechanics and its Applications 341 (2004) C, pp. 433-443

Using the Huang–Yang–Luttinger and Lee–Yang virial expansions of a dilute Bose gas as well as our theory of phase transition, we show that in the dilute limit, the critical temperature of Bose–Einstein condensation of a Bose gas is given by [Tc−Tc(0)]/Tc(0)=γn1/3a,...

The Core of a Normal Form Game

Kóczy, László Á. - EconWPA - 2003

Due to the externalities, in normal form games a deviation changes the payoff of all players inducing a retaliation by the remaining or residual players. The stability of an outcome depends on the expectations potential deviators have about this reaction, but so far no satisfactory theory has...

A Note on Funaki and Yamato's Tragedy of the Commons

Kóczy, László Á. - EconWPA - 2002

In the model of Funaki and Yamato (1999) the tragedy of the commons can be avoided with pessimistic players, while this does not hold for optimistic players. We propose a new core concept to overcome this puzzle and provide numerical simulations of simple games where the conclusions coincide or...

Calculation of the partition function using quantum genetic algorithms

Grigorenko, I; Garcia, M.E - In: Physica A: Statistical Mechanics and its Applications 313 (2002) 3, pp. 463-470

We present a new method based on genetic algorithms which permits to determine efficiently the partition function and … eigenfunctions for a given Hamiltonian, while the partition function attains its global extremum (maximum) for a given temperature …. We calculate the spectrum and the partition function in the case of few interacting particles in one-dimensional infinite …

The Core of a Partition Function Game

Kóczy, László Á. - EconWPA - 2001

We consider partition function games and introduce new defini-tions of the core that include the effects of … with fewer players and with a partition function that captures the externalities of the deviating coalition. Some …
