Perspective: Fifty years of density-functional theory in chemical physics.

open access: yesJournal of Chemical Physics, 2014
Since its formal inception in 1964-1965, Kohn-Sham density-functional theory (KS-DFT) has become the most popular electronic structure method in computational physics and chemistry.

QCD at Finite temperature and density with staggered and Wilson quarks [PDF]

open access: yes, 2004
One of the most challenging issues in particle physics is to study QCD in extreme conditions. Precise determination of the QCD phase diagram on temperature $T$ and chemical potential $\mu$ plane will provide valuable information for quark-gluon plasma ...

Imaginary chemical potential and finite fermion density on the lattice [PDF]

open access: yes, 1998
Standard lattice fermion algorithms run into the well-known sign problem at real chemical potential. In this paper we investigate the possibility of using imaginary chemical potential, and argue that it has advantages over other methods, particularly for

The Phases of QCD in Heavy Ion Collisions and Compact Stars [PDF]

open access: yes, 2000
I review arguments for the existence of a critical point in the QCD phase diagram as a function of temperature and baryon chemical potential. I describe how heavy ion collision experiments at the SPS and RHIC can discover the tell-tale signatures of such

New Lewis Structures through the application of the Hypertorus Electron Model [PDF]

open access: yes, 2010
The hypertorus electron model is applied to the chemical bond. As a consequence, the bond topology can be determined. A linear correlation is found between the normalized bond area and the bond energy. The normalization number is a whole number.

Welcome to Atoms: A New Open Access Journal

open access: yesAtoms, 2012
There is no doubt that it is an exciting time to be studying quantum properties of atoms, molecules, and nuclei. Increasingly deep connections between long-established fields: “atomic physics”, “molecular physics”, “chemical physics”, “nuclear physics”, “

Pure vibrational state energies and statistical-mechanical models for the reparameterized scarf oscillator

open access: yesFrontiers in Physics, 2023
In this work, the reparameterized Scarf II oscillator was employed to describe the internal vibration of diatomic systems. Analytical equations for bound state pure vibrational energies and canonical partition function were obtained.

Tsallis Statistics in High Energy Physics: Chemical and Thermal Freeze-Outs

open access: yesPhysics, 2020
We present an overview of a proposal in relativistic proton-proton (pp) collisions emphasizing the thermal or kinetic freeze-out stage in the framework of the Tsallis distribution.

Eugene P. Wigner’s Visionary Contributions to Generations-I through IV Fission Reactors

open access: yesEPJ Web of Conferences, 2014
Among Europe’s greatest scientists who fled to Britain and America in the 1930s, Eugene P. Wigner made instrumental advances in reactor physics, reactor design and technology, and spent nuclear fuel processing for both purposes of developing atomic ...

Prospects for strangeness measurement in ALICE [PDF]

open access: yes, 2008
The study of strangeness production at LHC will bring significant information on the bulk chemical properties, its dynamics and the hadronisation mechanisms involved at these energies.
