Spin 1/2 Fermions in the Unitary Regime: A Superfluid of a New Type [PDF]

open access: yes, 2006
We have studied, in a fully non-perturbative calculation, a dilute system of spin 1/2 interacting fermions, characterized by an infinite scattering length at finite temperatures.

Size-dependent thermodynamic description of the binary Pb-Sn system [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2017
Recently, a new thermodynamic description of the binary Pb - Sn system was proposed and it seems to be interesting to extend this description on the system, where size of particles plays a key-role.

On the Analysis and Assessment of First-Order Group Contribution Models for the Calculation of Normal Boiling Point and Critical Properties of Pure Compounds

open access: yesInternational Journal of Chemical Engineering, 2022
The thermodynamic properties of pure compounds are relevant data for process systems engineering. Different first-order group contribution models have been reported in the literature to calculate these properties and they are also widely employed in ...

Evolution of inclusions in calcium-treated H13 die steel

open access: yes工程科学学报, 2018
The laboratory experiments of inclusions in H13 die steel modified by Ca treatment were employed in a vacuum induction furnace and the inclusions were analyzed using a scanning electron microscope equipped with an energy dispersive spectrometer in the ...

Link between K-absorption edges and thermodynamic properties of warm-dense plasmas established by improved first-principles method

open access: yes, 2015
A precise calculation that translates shifts of X-ray K-absorption edges to variations of thermodynamic properties allows quantitative characterization of interior thermodynamic properties of warm dense plasmas by X-ray absorption techniques, which ...

Monte Carlo computation of pair correlations in excited nuclei [PDF]

open access: yes, 1995
We present a novel quantum Monte Carlo method based on a path integral in Fock space, which allows to compute finite-temperature properties of a many-body nuclear system with a monopole pairing interaction in the canonical ensemble.

Generalized Maxwell equal area law and black holes in complex free energy

open access: yesPhysics Letters B
Maxwell equal area law is an important and traditional analytical tool in thermodynamic phase transition, especially in the calculation of gas-liquid phase transition, which reconciles the theoretical calculation with the experimental results ...

Thermodynamic properties of ions in solution - activity calculation

open access: yesVértices, 2011
Due to the interaction between ions in solution, the concept of concentration is inadequate. Thus, the term activity is a more appropriate concept, as it takes into account the activity coefficient of ions, which are very well estimated in dilute ...
