Diffusion models (DMs) are a class of generative machine learning methods that sample a target distribution by transforming samples of a trivial (often Gaussian) distribution using a learned stochastic differential equation. In standard DMs...

In recent studies, it has been established that higher-order interactions in coupled oscillators can induce a process from continuous to explosive phase transition. In this study, we identify a phase transition, termed the stepwise explosiv...

Already some years ago, Langdon [Phys. Rev. Lett. 44, 575 (1980)10.1103/PhysRevLett.44.575] proposed that inverse bremsstrahlung absorption in plasmas drives free electrons into non-Maxwellian distributions. Radiation-hydrodynamic simulatio...

We propose a vertex representation of the tensor network (TN) for classical spin systems on hyperbolic lattices. The tensors form a network of regular p-sided polygons (p>4) with the coordination number 4. The response to multistate spin sy...

The effectiveness of physics-informed neural networks (PINNs) for learning the dynamics of constrained Hamiltonian systems is demonstrated using the Dirac theory of constraints for regular systems with holonomic constraints and systems with...

The evolution operator method is used to solve the generalized Fokker-Planck equations and the generalized diffusion-wave equations in the (1+1)-dimensional space in which x∈R and t∈R_{+}. These equations contain either the first- or the ...

The kinesin superfamily of motor proteins is a major driver of anterograde transport of vesicles and organelles within eukaryotic cells via microtubules. Numerous studies have elucidated the step size, velocities, forces, and navigation abi...
Fast and slow escapes in forced chaotic scattering: The Newtonian and the relativistic regimes [0.03%]

We study chaotic scattering phenomena in the paradigmatic Hénon-Heiles Hamiltonian when a rotating external force is applied. This analysis builds on and extends our previous work on the relativistic unperturbed case and the classical case...
Emergence in kinetic roughening with long-range temporal correlations [0.03%]

The role of long-range temporal correlations in kinetic roughening processes is significant, potentially influencing surface morphologies and dynamic scaling properties. This type of correlation, acting as a nonlocal interaction during grow...
