We show that the time-resolved dynamics of an underdamped harmonic oscillator can be used to do multifunctional computation, performing distinct computations at distinct times within a single dynamical trajectory. We consider the amplitude ...
Rare, noise-induced, bypass transition in plane Couette flow can bypass instantons [0.03%]

This paper presents a study of rare noise-induced transitions from stable laminar flow to transitional turbulence in plane Couette flow, which we will term buildup. We wish to study forced paths that go all the way from laminar to turbulent...
Multifractality and excited-state quantum phase transition in ferromagnetic spin-1 Bose-Einstein condensates [0.03%]

Multifractality of quantum states plays an important role for understanding numerous complex phenomena observed in different branches of physics. The multifractal properties of the eigenstates allow for characterising various phase transiti...
Negative large deviations of the front velocity of N-particle branching Brownian motion [0.03%]

We study negative large deviations of the long-time empirical front velocity of the center of mass of the one-sided N-BBM (N-particle branching Brownian motion) system in one dimension. Employing the macroscopic fluctuation theory, we study...

We consider a run-and-tumble particle whose speed and tumbling rate are space dependent on an infinite line. Unlike most of the previous work on such models, here we make the physical assumption that at large distances, these rates saturate...
Monte Carlo study of the two-dimensional kinetic Ising model under a nonantisymmetric magnetic field [0.03%]

We present a comprehensive numerical study of dynamic phase transitions in the two-dimensional kinetic Ising model under a nonantisymmetric time-dependent magnetic field including a sinusoidal term and a second harmonic component. We demons...
Absorption of electromagnetic waves at oblique resonance in plasmas threaded by inhomogenous magnetic fields [0.03%]

There has been of significant interest lately in the study of electromagnetic (EM) waves interacting with magnetized plasmas. The variety of resonances and the existence of several pass and stop bands in the dispersion curve for different o...

We consider the critical behavior of two-dimensional Potts models in the presence of a bond disorder in which the correlation decays as a power law. In some recent work the thermal sector of this theory was investigated by a renormalization...
Defect versus defect: Stationary states of single-file marching in periodic landscapes with road blocks [0.03%]

Totally asymmetric simple exclusion process (TASEP) sets the paradigm for one-dimensional driven single-file motion. We study a periodic TASEP with two road blocks or defects of different kinds, one point and another extended, across which ...

It has recently been shown that networks possessing scale-free and fractal properties may exhibit a bifractal nature, in which local structures are described by two different fractal dimensions. In this study, we investigate random walks on...
