Self avoiding random surfaces on a cubic lattice are studied by extensive Monte Carlo sampling The surfaces have empty boundary and the topology of a sphere An oct tree data structure allows to obtain good statistics for surfaces whose plaquette number is almost an order of magnitude greater than in previous investigations Maximum likelihood determinations of the critical plaquette fugacity and...

Strangeness production in heavy ion collisions at relativistic energies provides one of the key information about the reaction mechanism and could indicate the onset of new phenomena. The attempts to describe the measured particle ratios including strange hadrons at AGS and SPS and recently also at RHIC using a strangeness fugacity are very successful [1, 2, 3, 4, 5]. However, the usual grand-c...

We study the inflated phase of two dimensional lattice polygons, both convex and column-convex, with fixed area A and variable perimeter, when a weight μ exp[−Jb] is associated to a polygon with perimeter t and b bends. The mean perimeter is calculated as a function of the fugacity μ and the bending rigidity J . In the limit μ → 0, the mean perimeter has the asymptotic behaviour 〈t〉/4 √ A ≃ 1−K...

We review the overlap pathology of the Glasgow reweighting method for finite density QCD, and discuss the sampling bias that effects the determination of the ensemble-averaged fugacity polynomial expansion coefficients that form the Grand Canonical Partition function. The expectation of the difference in free energies between canonical partition functions generated with different measures is pr...

Abstract Magma oceans (MOs) are episodes of large-scale melting the mantle terrestrial planets. The energy delivered by Moon-forming impact induced a deep MO on young Earth, corresponding to last episode core-mantle equilibration. crystallization this led outgassing volatiles initially present in Earth’s mantle, resulting formation secondary atmosphere. During outgassing, acts as chemical buffe...

Sulfur is a key element in terrestrial magmatic processes yet its geochemical behavior remains one of the most difficult to model due heterovalent chemistry. The maximum amount sulfur silicate melt can dissolve before saturating with sulfide (e.g., pyrrhotite) or sulfate anhydrite) changes redox state system and has important implications for budget system. Several empirical models have been de...
