On the quantum (in)stability in cavity QED [PDF]
, 2005 The stability and instability of quantum motion is studied in the context of cavity quantum electrodynamics (QED). It is shown that the Jaynes-Cummings dynamics can be unstable in the regime of chaotic walking of an atom in the quantized field of a ...

Collective dynamics from stochastic thermodynamics
New Journal of Physics, 2015 From a viewpoint of stochastic thermodynamics, we derive equations that describe the collective dynamics near the order-disorder transition in the globally coupled XY model and near the synchronization–desynchronization transition in the Kuramoto model ...

Dynamics of tidal synchronization and orbit circularization of celestial bodies [PDF]
, 2008 PACS number s : 05.45.Xt, 05.45.Gg, 95.10.Ce, 96.15.DeWe take a dynamical-systems approach to study the qualitative dynamical aspects of the tidal locking of the rotation of secondary celestial bodies with their orbital motion around the primary.

Synchronization in networks of mutually delay-coupled phase-locked loops
New Journal of Physics, 2014 Electronic components that perform tasks in a concerted way rely on a common time reference. For instance, parallel computing demands synchronous clocking of multiple cores or processors to reliably carry out joint computations.

New Journal of Physics, 2014 We study the collective dynamics of excitatory integrate-and-fire-like oscillators interacting via δ -pulses on a small-world network. The oscillators are endowed with refractory periods and time delays.

Generalized Phase Synchronization in unidirectionally coupled chaotic oscillators [PDF]
, 2003 We investigate phase synchronization between two identical or detuned response oscillators coupled to a slightly different drive oscillator. Our result is that phase synchronization can occur between response oscillators when they are driven by ...

Robustness and Enhancement of Neural Synchronization by Activity-Dependent Coupling [PDF]
, 2002 We study the synchronization of two model neurons coupled through a synapse having an activity-dependent strength. Our synapse follows the rules of Spike-Timing Dependent Plasticity (STDP).

Driven discrete time quantum walks
New Journal of Physics, 2016 We introduce the driven discrete time quantum walk (QW), where walkers are added during the walk instead of only at the beginning. This leads to interference in walker number and very different dynamics when compared to the original QW.

Role of delay for the symmetry in the dynamics of networks [PDF]
, 1994 PACS number(s): 05.45.Xt, 89.75.Kd, 89.75.Hc, 02.30.KsThe symmetry in a network of oscillators determines the spatiotemporal patterns of activity that can emerge. We study how a delay in the coupling affects symmetry-breaking and -restoring bifurcations.

Generalized convergence analysis of the fractional order systems
Open Physics, 2018 The aim of the present work is to generalize the contraction theory for the analysis of the convergence of fractional order systems for both continuous-time and discrete-time systems.
