“…When considering the interaction of nucleons at short enough distances, the point particle assumption is not proper and the size of the nucleon should be taken into account. In CoMD [8,9,10,11,12,13,14], the nucleons are assumed to have a Gaussian distribution with width σ r…”

The correction to the Coulomb energy due to virtual production of e + e − pairs, which is on the order of one percent of the Coulomb energy at nuclear scales is discussed. The effects of including a pair-production term in the semi-empirical mass formula and the correction to the Coulomb barrier for a handful of nuclear collisions using the Bass and Coulomb potentials are studied. With an eye toward future work using Constrained Molecular Dynamics (CoMD) model, we also calculate the correction to the Coulomb energy and force between protons after folding with a Gaussian spatial distribution.

“…In this first paper we only discuss the perturbative effect on the energy. We will introduce the correction into the microscopic model Constrained Molecular Dynamics (CoMD) [8,9,10,11,12,13,14], and in following research we will discuss actual production. The structure of this paper is as follows.…”

“…In contrast, the field of computational plasma physics has traditionally relied on hydrodynamics [5,6] and kinetic [7,8] codes because the temporal and spatial scales of interest are much too large for MD to be tractable; moreover, the detailed description of discrete particles is less important and instead macroscopic field variables are computed. However, MD plays a central role in a diverse set of plasma subfields concerned with understanding microscopic particles such as astrophysical systems [9,10], dusty plasmas [11,12], ultracold neutral plasmas [13,14], dense plasmas [15,16], low temperature plasmas [17,18], plasma beams [19,20], quark-gluon plasmas [21,22], etc.…”

We present an open-source, performant, pure-python molecular dynamics (MD) suite for non-ideal plasmas. The code, Sarkas, aims to accelerate the research process by providing an MD code but also pre-and post-processing tools. Sarkas offers the ease of use of Python while employing the Numba library to obtain execution speeds comparable to that of compiled languages. The available tools in Sarkas include graphical displays of the equilibration process through a Jupyter interface and the ability to compute quantities such as, radial distribution functions, autocorrelation functions and Green-Kubo relations. Many force laws used to simulate plasmas are included in Sarkas, namely, pure Coulomb, Yukawa, and Molière pair-potentials. Sarkas also contains quantum statistical potentials and fast Ewald methods are included where necessary. An object-oriented approach allows for easy modification of Sarkas, such as adding new time integrators, boundary conditions and force laws.

“…One possibility to avoid this problem is, instead of using the Pauli potential, to maintain the Pauli principle of the system by stochastic rearrangements of particle momenta [25]. This model was originally developed for nucleon systems and was applied also to the quark system very recently [26].…”

Molecular dynamics simulation for the baryon-quark phase transition at finite baryon density

et al. 2005

Abstract. We study the baryon-quark phase transition in a molecular dynamics (MD) of quark degrees of freedom at finite temperature and density. The baryon state at low density and temperature, and the deconfined quark state at high density and temperature are reproduced. We investigate the equations of state of matters with different u-d-s compositions. Then we draw phase diagrams in the temperaturedensity plane by this simulation. It is found that the baryon-quark transition is sensitive to the quark width. PACS. PACS-key discribing text of that key -PACS-key discribing text of that key
