Correspondence Principle for Many-Body Scars in Ultracold Rydberg Atoms
Physical Review X, 2021 The theory of quantum scarring—a remarkable violation of quantum unique ergodicity—rests on two complementary pillars: the existence of unstable classical periodic orbits and the so-called quasimodes, i.e., the nonergodic states that strongly overlap ...

Periodic orbits in warped disks [PDF]
Astronomy & Astrophysics, 2001 It is often assumed that a warped galaxy can be modeled by a set of rings. This paper verifies numerically the validity of this assumption by the study of periodic orbits populating a heavy self-gravitating warped disk. The phase space structure of a warped model reveals that the circular periodic orbits of a flat disk are transformed in quasi annular ...

Existence and Stability of nT-Periodic Orbits in the Boost Converter
Applied Sciences, 2022 In high load conditions, the boost converter presents some phenomena, such as chattering, chaos, subharmonics, and nT-periodic orbits, which require studying them with the aim of reducing the effects and improving the performance of these electronic ...

Model Reduction Near Periodic Orbits of Hybrid Dynamical Systems [PDF]
IEEE Transactions on Automatic Control, 2013 We show that, near periodic orbits, a class of hybrid models can be reduced to or approximated by smooth continuous-time dynamical systems. Specifically, near an exponentially stable periodic orbit undergoing isolated transitions in a hybrid dynamical ...

, 2005 We propose the Particle Swarm Optimization (PSO) as an alternative method for locating periodic orbits in a three--dimensional (3D) model of barred galaxies. We develop an appropriate scheme that transforms the problem of finding periodic orbits into the

Moving average network examples for asymptotically stable periodic orbits of monotone maps
Electronic Journal of Qualitative Theory of Differential Equations, 2018 For a certain type of discrete-time nonlinear consensus dynamics, asymptotically stable periodic orbits are constructed. Based on a simple ordinal pattern assumption, the Frucht graph, two Petersen septets, hypercubes, a technical class of circulant ...

FEBS Letters, EarlyView.Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Bifurcation of Limit Cycles of a Class of Piecewise Linear Differential Systems in with Three Zones
Discrete Dynamics in Nature and Society, 2013 We study the bifurcation of limit cycles from periodic orbits of a four-dimensional system when the perturbation is piecewise linear with two switching boundaries.

Precessing and periodic motions around a black-bounce/traversable wormhole
European Physical Journal C: Particles and Fields, 2020 We investigate precessing and periodic geodesic motions of timelike particles around a black-bounce/traversable wormhole. After obtaining its semi-classic and relativistic periastron advance, we find a preliminary bound on the scale length of such a ...
