Communications on Pure and Applied Mathematics, EarlyView.Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

ChemPhysChem, Accepted Article.Atomically dispersed Fe‐N‐C catalysts with high oxygen reduction reaction (ORR) activity have attracted great attention since the last decade. Due to its comparable ORR activity and low material cost, it is a promising platinum‐group metal (PGM) free catalyst that can replace the commercialized Pt/C materials; furthermore, it can facilitate the ...

Vibrational Partition Functions from Bond Order and Populations Relationships
ChemPhysChem, EarlyView.A new computational model is presented that predicts vibrational partition functions using bond orders and populations relationships (QBOP). This model demonstrates that thermochemical energy contributions can be reasonably approximated based on well‐conditioned orbital populations without the need for a costly Hessian calculation.

Physics‐Based Inverse Modeling of Battery Degradation with Bayesian Methods
ChemSusChem, EarlyView.Active parameterization of physics‐based models is essential to drive battery science. However, due to the model's complexity, parameterization is an ill‐posed problem with uncertainties in models and data. In this article, Bayesian methods are applied to physical degradation models to show sample‐efficient parameterization with uncertainty ...

On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas
Contributions to Plasma Physics, EarlyView.ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures
Contributions to Plasma Physics, EarlyView.ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Instantaneous Normal Modes of Yukawa Liquids
Contributions to Plasma Physics, EarlyView.ABSTRACT The instantaneous normal mode (INM) approach, which extends the normal mode description of collective excitations in solids to liquids, is applied to strongly coupled, three‐dimensional Yukawa liquids. Based on data from Langevin dynamics simulations, we compute the instantaneous normal modes across a wide range of coupling and screening ...

Dynamic Properties of the Warm Dense Uniform Electron Gas With the qSTLS Dielectric Scheme
Contributions to Plasma Physics, EarlyView.ABSTRACT The recently derived Fourier–Matsubara expansion of imaginary–time correlation functions comprises an exact result of linear response theory for finite‐temperature quantum many‐body systems. In its density–density version, the expansion facilitates systematic comparisons between quasi‐exact ab initio path integral Monte Carlo simulations and ...
