Comparing matrix models and QCD lattice data with chemical potential [PDF]
Nucl.Phys.B(Proc.Suppl.)129&130(2004)527, 2003 We present a quantitative analysis of the microscopic Dirac spectrum which is complex in the presence of a non-vanishing quark chemical potential. Data from quenched SU(3) lattice simulations for different volumes V and small values of the chemical potential are compared to analytical predictions from matrix models.

Data-driven discovery of multiscale chemical reactions governed by the law of mass action [PDF]
, 2021 In this paper, we propose a data-driven method to discover multiscale chemical reactions governed by the law of mass action. First, we use a single matrix to represent the stoichiometric coefficients for both the reactants and products in a system without catalysis reactions. The negative entries in the matrix denote the stoichiometric coefficients for

A Random Matrix Model for Color Superconductivity at Zero Chemical Potential [PDF]
Phys.Rev. D61 (2000) 076004, 1999 We discuss random matrix models for the spontaneous breaking of both chiral and color symmetries at zero chemical potential and finite temperature. Exploring different Lorentz and gauge symmetric color structures of the random matrix interactions, we find that spontaneous chiral symmetry breaking is always thermodynamically preferred over diquark ...

Localized corrosion induced surface modifications of Al-Cu-Li alloy studied by ToF-SIMS 3D imaging
npj Materials Degradation, 2021 Three-dimensional (3D) time-of-flight secondary ion mass spectrometry (ToF-SIMS) imaging is a promising tool in the analysis of surface modifications of alloy matrix and intermetallic particles induced by localized corrosion due to its good spatial ...

pyJac: analytical Jacobian generator for chemical kinetics [PDF]
Comput. Phys. Comm. 215 (2017) 188-203, 2016 Accurate simulations of combustion phenomena require the use of detailed chemical kinetics in order to capture limit phenomena such as ignition and extinction as well as predict pollutant formation. However, the chemical kinetic models for hydrocarbon fuels of practical interest typically have large numbers of species and reactions and exhibit high ...
