The configuration path integral Monte Carlo (CPIMC) method is employed to perform first-principles simulations of warm dense matter based on atomic orbitals. The system is modeled as an ion sphere with a pointlike nucleus at its center, and the electronic many-body problem is solved using CPIMC with…

We develop a long-wavelength theory for the linear stability of a diffuse interface between an active nematic and an isotropic phase. The starting point is a Cahn-Hilliard-Landau-de Gennes description of the coexistence profile, coupled to Brinkman-screened Stokes hydrodynamics. Small perturbations …

We present a framework for chemical learning based on competitive dimerization networks (CDNs)—systems in which multiple molecular species, e.g., proteins or DNA-RNA oligomers, reversibly bind to form dimers. We show numerically that these networks can, in principle, be trained in vitro through dire…

This paper presents a predictive framework to scale granular flow from Earth to other gravitational environments, and shows that low gravity dramatically increases the probability of clogging. These findings explain previous contradictory results and establish a foundation for predicting and controlling granular flow in space.

Mass disorder attenuates solitary waves traveling through Hertzian chains in a way that resembles viscous damping, even though the microscopic dynamics remains Hamiltonian and conserves energy. We show that this attenuation depends not only on the strength of the disorder, but also on its spatial or…

In this paper, we use the Feingold-Peres model, a well-known paradigm of quantum chaos, as an example. Using semiclassical analysis and numerical simulations, we investigate the statistical properties of observables in few-body systems with chaotic classical limits and the emergence of random-matrix…

We study the thermalization properties of a fully nonlinear lattice model originally derived from the two-dimensional cubic defocusing nonlinear Schrödinger equation (NLS) using analytical and numerical methods. The model conserves both energy and norm, whose densities define a microcanonical energy…

Accurate reliability assessment of interconnected and interdependent systems requires explicit representation of interaction mechanisms arising from shared components, load redistribution, feedback coupling, and correlated degradation. Classical system reliability theory is formulated using real-val…

We study wave turbulence in systems with two special properties: a large number of fields (large $N$) and a nonlinear interaction that is strongly local in momentum space. The first property allows us to find the kinetic equation at all interaction strengths—both weak and strong, at leading order in $1\dots$

A laser induced fluorescence (LIF) scheme is investigated to probe singly ionized iodine ions (${\mathrm{I}}^{+}$) in electric propulsion devices. The transition $6s{}^{5}S_2^{\mathrm{o}}\to 6p{}^{5}P_3$ at 516.261 nm is considered and the theoretical computation of the weights and positions of the hyperfine structure is carried out. First, th…

We develop a statistical theory of temporal learnability in recurrent neural networks, quantifying the maximal temporal horizon ${\mathcal{H}}_N$ over which gradient-based learning can recover lag-dependent structure at finite sample size $N$. The theory is built on the effective learning rate envelope $f\left(\ell \right)$, a funct…
