The Stokes-Einstein (SE) relation, which relates diffusion constants with the viscosity of a liquid at high temperatures in equilibrium, is violated in the supercooled temperature regime. Whether this relation is obeyed in nonequilibrium ac...

With an increasing number of observations on the dynamics of many complex systems, it is necessary to reveal the underlying mechanisms behind these complex dynamics, which is fundamentally important in many scientific fields such as climate...
Divergence asymmetry and connected components in a general duplication-divergence graph model [0.03%]

This Letter introduces a generalization of known duplication-divergence models for growing random graphs. This general duplication-divergence model includes a coupled divergence asymmetry rate, which allows to obtain the structure of random...

A considerable number of semiempirical and first-principles models have been created to describe the dynamic response of a collisionally damped charged-particle system. However, known challenges persist for established dynamic structure fac...
Two-component lattice Boltzmann model for solute transport in bubbly flows [0.03%]

A free energy lattice Boltzmann model has been developed to describe a binary system consisting of a nonideal solvent and a gaseous ideal solute. A free energy functional to describe this mixture has been derived, and it is used to determin...

Time crystals are many-body systems that spontaneously break time-translation symmetry, and thus exhibit long-range spatiotemporal order and robust periodic motion. Recent results have shown that coupling an external packing field to densit...
Vortex solitons in quasi-phase-matched photonic crystals with competing quadratic and cubic nonlinearity [0.03%]

We introduce a methodology for investigating vortex solitons (VSs) within quasi-phase-matched (QPM) photonic crystals, featuring competing quadratic and cubic nonlinearities. The photonic crystal is introduced with a checkerboard structure,...
Transition from alternating stripes to alternating labyrinths in oscillatory media [0.03%]

Alternating (temporally period-2) stripes and labyrinths have been observed in media of chemical and biochemical reactions; however, the mechanisms underlying the formation of these spatiotemporal patterns remain unclear. Here, we conduct c...
Towards a foundation model for partial differential equations: Multioperator learning and extrapolation [0.03%]

Calcium signals in pancreatic β cell collectives show a sharp transition from uncorrelated to correlated state resembling a phase transition as the slowly increasing glucose concentration crosses the tipping point. However, the exact natur...
