The persistent assembly and clustering in active systems, ranging from biological aggregates to synthetic active matter, is governed by the interplay of self-propulsion, environmental stimulus, and interparticle interactions. This study inv...

This work investigates the unidirectional transport of charged particles across magnetic field lines driven by magnetosonic solitons in a collisionless plasma. Within the framework of a magnetohydrodynamic model, numerical solutions as well...

We analytically solve the critical dynamics of the Kob-Andersen kinetically constrained model of supercooled liquids on the Bethe lattice, employing a combinatorial argument based on the cavity method. For arbitrary values of graph connecti...
Shear flow of frictional spheroids: Comparison between elongated and flattened particles [0.03%]

The rheology of dense granular shear flows is influenced by friction and particle shape. We investigate numerically the impact of nonspherical particle geometries under shear on packing fraction, stress ratios, velocity fluctuations, force ...

We develop two complementary generative mechanisms that explain when and why Benford's first-digit law arises. First, a probabilistic Turing machine (PTM) ensemble induces a geometric law for codelength. Maximizing its entropy under a const...
Effects of overburden pressure on granular shear flows: Multiplicity and chaos [0.03%]

The shear flow of granular materials is studied in the presence of overburden pressure and gravity using the discrete element method. The system comprises particles confined between parallel walls moving with constant speed in opposite dire...

We present a numerical analysis of the translational motion of dimers composed of charged dielectric particles immersed in aqueous electrolytes under ac electric fields. The dimers consist of two spheres with different radii and are studied...

We investigate density fluctuations in three-dimensional chiral active fluids by using a simple model of helical self-propelled particles. Helical motion is generated by a constant angular velocity (or chiral torque) acting on the self-prop...
Classical out-of-time-order correlators for Bose-Hubbard systems and their relation to the finite-time Lyapunov exponent [0.03%]

The out-of-time-order correlator (OTOC) is studied for a bosonic quantum lattice model. We gain its classical analog through the replacement of both commutators appearing in the quantum correlator by a corresponding Poisson bracket. The eva...
Transient flow of a binary gas mixture through a long capillary at arbitrary rarefaction parameters [0.03%]

This work proposes a model to simulate transient flow of a gas mixture at arbitrary rarefaction parameters and molar fractions through a long capillary. The transient model is based on the linear relationship between the thermodynamic fluxe...
