We simulate the N-spin critical Ising model on a square lattice using Glauber dynamics and consider the typical one-unit time equal to N single-spin-flip attempts. The divergence of correlation time with the linear extent of the system resu...

Making sense of complex inhomogeneous systems composed of many interacting species is a grand challenge that pervades basically all natural sciences. Phase separation and pattern formation in reaction-diffusion systems have been largely stu...

We consider a generalization of the well-known SEIR model of epidemic spreading with two susceptible compartments and without permanent immunity. It is shown that the set of ordinary differential equations defining its dynamics can be cast ...

In traditional voter models, opinion dynamics are driven by interactions between individuals, where an individual adopts the opinion of a randomly chosen neighbor. However, these models often fail to capture the emergence of entirely new op...

The investigation of water's glass transition and a possible liquid-liquid transition within its supercooled state is hampered by its inevitable crystallization in a temperature range, termed "no-man's land." Here we report dielectric-spect...

The relaxation oscillation in sliding systems is termed stick-slip (SS) since the two surfaces in contact seem to repeat the stick and slip states. However, several precise measurements have revealed that extremely slow slip occurs in even ...

We adopt a stochastic approach to study the charge transport in transistors. In this approach, the hole and electron densities are ruled by diffusion-reaction stochastic partial differential equations satisfying a local detailed balance con...

Drop coalescence plays a crucial role in nature and industry. In continuum theory, after the two drops are taken to touch at a point at the onset of coalescence, two scaling regimes for the temporal growth of the bridge connecting the drops...

The construction of accurate interatomic potentials, and related fields of forces, from equilibrium conformational distributions of molecules is a crucial step in coarse-grained modeling. In this work we show that in order to develop accura...

The speed of sound of simple dense fluids exhibits a pronounced freezing temperature scaling of the form c_{s}/v_{T}≃sqrt[γ]+α(T_{fr}/T)^{β}, where c_{s} is the speed of sound, v_{T} is the characteristic thermal velocity, γ is the ide...
