Staggered Fermion Actions with Improved Rotational Invariance [PDF]

open access: yes, 1997
We introduce a class of improved actions for staggered fermions which to O(p^4) and O(p^6), respectively, lead to rotationally invariant propagators. We discuss the resulting reduction of flavour symmetry breaking in the meson spectrum and comment on the

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 ...

On the calculation of equilibrium thermodynamic properties from molecular dynamics.

open access: yesPhysical Chemistry, Chemical Physics - PCCP, 2016
The purpose of statistical mechanics is to provide a route to the calculation of macroscopic properties of matter from their constituent microscopic components. It is well known that the macrostates emerge as ensemble averages of microstates.

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.

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 ...

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 ...

Phase Formation and Microstructure Evolution of Al-5Si-0.8Mg Alloys with Different Mn Concentrations

open access: yesMetals, 2021
Mg-containing high-Si aluminum alloys are heat-treatable alloys that are widely used in industry. Substantial attention has been paid to increasing the performance of such alloys by adding a small amount of Mn, which is an effective and common alloying ...
