Article Abstract
Single molecule junctions are important examples of complex out-of-equilibrium many-body quantum systems. We identify a nontrivial clustering of steady state populations into distinctive subspaces with Boltzmann-like statistics, which persist far from equilibrium. Such Boltzmann subspaces significantly reduce the information needed to describe the steady state, enabling modeling of high-dimensional systems that are otherwise beyond the reach of current computations. The emergence of Boltzmann subspaces is demonstrated analytically and numerically for fermionic transport systems of increasing complexity.

Single molecule junctions enable us to study molecules in new states far from equilibrium. In this work, we focus on molecules under a thermal bias imposed by coupling to two electrodes at different temperatures. We demonstrate that within the realm of weak electrode-molecule coupling (Pauli master equations), even far from equilibrium, the molecule can be assigned (at least approximately) an effective temperature at steady state.

We investigated the inhibitory potency of aryloxyacetic acid derivatives (AADs) on 4-hydroxyphenylpyruvate dioxygenase (HPPD), a crucial enzyme target for HPPD herbicide development. Developing a wide-ranging approach combining reported structure-activity relationships (SARs with the observed inhibitory potencies of the enzyme ), our simulations for molecular mechanics Poisson-Boltzmann (MM-PB) complexation quantitative SAR (QSAR) (computed relative Gibbs free energies of the HPPD-AADx complex formation ΔΔ), and three-dimensional (3D)-QSAR pharmacophore (PH4) models for screening the chemical subspace of aryloxyacetic acid derivatives (a virtual library of AADs, VL), we come out with a handful of novel AADs with promising predictive HPPD inhibitory potency and confirmed molecular dynamics (MD) conformational stability. The 3D-QSAR model revealed a correlation (p = × ΔΔ + ) between computed data and observed inhibition ones: p = -0.

For a system of N≫1 spinless quantum particles, the projection operator is introduced, which, surprisingly, exactly transforms the inhomogeneous (with irrelevant initial correlations term) Nakajima-Zwanzig generalized master equation (GME) into completely closed (homogeneous) GME with initial correlations included into the kernel governing its evolution. The obtained equation is equivalent to the closed linear evolution equation for an S-particle (S

Article Synopsis
- Single molecule junctions serve as complex quantum systems that are not in equilibrium, showcasing unique behaviors when analyzed.
- The study finds that these systems form distinct "Boltzmann subspaces" that help simplify the understanding of the steady state populations, making it easier to describe them.
- This phenomenon has been demonstrated through both analytical and numerical methods in increasingly complex fermionic transport systems, highlighting its significance in high-dimensional modeling.

A multiscale steady discrete unified gas kinetic scheme with macroscopic coarse mesh acceleration [accelerated steady discrete unified gas kinetic scheme (SDUGKS)] is proposed to improve the convergence of the original SDUGKS for an optically thick system in solving the multigroup neutron Boltzmann transport equation (NBTE) to analyze the distribution of fission energy in the reactor core. In the accelerated SDUGKS, by solving the coarse mesh macroscopic governing equations (MGEs) derived from the moment equations of the NBTE, the numerical solutions of the NBTE on fine meshes at the mesoscopic level can be rapidly obtained from the prolongation of the coarse mesh solutions of the MGE. Furthermore, the use of the coarse mesh can greatly reduce the computational variables and improve the computational efficiency of the MGE.
