We present analytical and numerical investigations of the size and shape evolution of localized disturbances during their propagation in elastic media (furthermore, we refer to this process as energy dispersion). We consider two models of m...

Wave dynamics in disordered open media is an intriguing topic and has lately attracted a lot of attention in non-Hermitian physics, especially in photonics. In fact, spatial distributions of gain and loss elements are physically possible in...

Individual species may experience diverse outcomes, from prosperity to extinction, in an ecological community subject to external and internal variations. Despite the wealth of theoretical results derived from random matrix ensembles, a the...

We explore the critical properties of the recently discovered finite-time dynamical phase transition in the nonequilibrium relaxation of Ising magnets after a temperature quench. The transition is characterized by a sudden switch in the rel...

Entropy production (EP) is a central quantity in nonequilibrium physics as it monitors energy dissipation, irreversibility, and free energy differences during thermodynamic transformations. Estimating EP, however, is challenging both theore...

Stochastic resonance is a phenomenon possessed by some nonlinear oscillators, in which a weak signal is boosted by noise. Both the monostable and bistable Duffing oscillators can exhibit this property. However, stochastic resonance has a st...

Reliability and accuracy of lateral correlation length measurements are studied and quantified from the analysis of synthetic correlated profiles. First, we review available methods to characterize self-affine profiles; we discuss the autoc...
Further results on the power-law decay of the fraction of the mixed eigenstates in kicked-top model with mixed-type classical phase space [0.03%]

By using the Krylov subspace technique to generate spin-coherent states in the kicked top model, a prototype model for studying quantum chaos, the accessible system size for studying the Husimi functions of eigenstates can be much larger th...

While renormalization groups are fundamental in physics, renormalization of complex networks remains vague in its conceptual definition and methodology. Here, we propose a novel strategy to renormalize complex networks. Rather than resortin...
Condensate-induced organization of the mass profile and emergent power laws in the Takayasu aggregation model [0.03%]

Large-mass condensates, which coexist with a power-law-decaying distribution in the one-dimensional Takayasu model of mass aggregation with input, were recently found in numerical simulations. Here, we establish the occurrence of condensate...
