Mesoscopic theory of flocking with alignment and antialignment copying
Chunming Zheng
We study a stochastic model of collective motion in which individuals update their orientation through pairwise aligning or anti-aligning copying interactions. We analyze both anne…
Impact of heavy-tailed synaptic strength distributions on self-sustained activity in networks of spiking neurons
Ralf Tönjes, Chunming Zheng, Wenping Cui +1
We analyze states of stationary activity in randomly coupled quadratic integrate-and-fire neurons using stochastic mean-field theory. Specifically, we consider the two cases of Gau…
Macroscopic dynamics of quadratic integrate-and-fire neurons subject to correlated noise
Hui Wang, Chunming Zheng
The presence of correlated noise, arising from a mixture of independent fluctuations and a common noisy input shared across the neural population, is a ubiquitous feature of neural…
Trade-off between coherence and dissipation for excitable phase oscillators
Chunming Zheng
Thermodynamic uncertainty relation (TUR) bounds coherence in stochastic oscillatory systems. In this paper, we show that both dynamical and thermodynamic bounds play important role…
Noise induced swarming of active particles
Chunming Zheng, Ralf Tönjes
We report on the effect of spatially correlated noise on the velocities of self propelled particles. Correlations in the random forces acting on self propelled particles can induce…
Transition to Synchrony in a Three-Dimensional Swarming Model with Helical Trajectories
Chunming Zheng, Ralf Toenjes, Arkady Pikovsky
We investigate the transition from incoherence to global collective motion in a three-dimensional swarming model of agents with helical trajectories, subject to noise and global co…
Stochastic bursting in unidirectionally delay-coupled noisy excitable systems
Chunming Zheng, Arkady Pikovsky
We show that \emph{stochastic bursting} is observed in a ring of unidirectional delay-coupled noisy excitable systems, thanks to the combinational action of time-delayed coupling a…
Repulsively Coupled Kuramoto-Sakaguchi Phase Oscillators Ensemble Subject to Common Noise
Chen Chris Gong, Chunming Zheng, Ralf Toenjes +1
We consider the Kuramoto-Sakaguchi model of identical coupled phase oscillators with a common noisy forcing. While common noise always tends to synchronize the oscillators, a stron…
Delay-induced stochastic bursting in excitable noisy systems
Chunming Zheng, Arkady Pikovsky
We show that a cumulative action of noise and delayed feedback on an excitable theta-neuron leads to rather coherent stochastic bursting. An idealized point process, valid if the c…
