Nanoscopic imaging of thick heterogeneous soft-matter structures in aqueous solution
Nature Communications, 2016 Integration time limits the capacity of super-resolution microscopy to study dynamics. Here, Bartsch et al. use the 3D scanning of a nanoparticle held in an optical trap, and its thermal noise motion within the trap, to image the local dynamics of soft ...

Surface ionization of metastable calcium atoms
AIP Advances, 2021 We report on an experimental study of surface ionization of metastable calcium atoms on a hot polycrystalline tungsten surface in vacuum. We implemented a hollow-cathode discharge to excite a fraction of calcium atoms in an atomic beam to metastable ...

Nonlinear cross-Kerr quasiclassical dynamics [PDF]
, 2013 We study the quasiclassical dynamics of the cross-Kerr effect. In this approximation, the typical periodical revivals of the decorrelation between the two polarization modes disappear and they remain entangled.

Neimark-Sacker Bifurcation in a Discrete-Time Financial System
Discrete Dynamics in Nature and Society, 2010 A discrete-time financial system is proposed by using forward Euler scheme. Based on explicit Neimark-Sacker bifurcation (also called Hopf bifurcation for map) criterion, normal form method and center manifold theory, the system's existence, stability ...

Rate of Convergence in Nonlinear Hartree Dynamics with Factorized Initial Data
, 2011 The mean field dynamics of an $N$-particle weekly interacting Boson system can be described by the nonlinear Hartree equation. In this paper, we present estimates on the 1/N rate of convergence of many-body Schr\"{o}dinger dynamics to the one-body ...

Complex Dynamics of an Adnascent-Type Game Model
Discrete Dynamics in Nature and Society, 2008 The paper presents a nonlinear discrete game model for two oligopolistic firms whose products are adnascent. (In biology, the term adnascent has only one sense, “growing to or on something else,” e.g., “moss is an adnascent plant.” See Webster's Revised ...

Extrema statistics in the dynamics of a non-Gaussian random field [PDF]
, 2012 When the equations that govern the dynamics of a random field are nonlinear, the field can develop with time non-Gaussian statistics even if its initial condition is Gaussian.

Weakly versus highly nonlinear dynamics in 1D systems
, 2005 We analyze the morphological transition of a one-dimensional system described by a scalar field, where a flat state looses its stability. This scalar field may for example account for the position of a crystal growth front, an order parameter, or a ...

Frequency-dependent fitness induces multistability in coevolutionary dynamics [PDF]
, 2012 Evolution is simultaneously driven by a number of processes such as mutation, competition and random sampling. Understanding which of these processes is dominating the collective evolutionary dynamics in dependence on system properties is a fundamental ...

Ascertaining when a basin is Wada: the merging method
Scientific Reports, 2018 Trying to imagine three regions separated by a unique boundary seems a difficult task. However, this is exactly what happens in many dynamical systems showing Wada basins.
