Mesoscopic theory of flocking with alignment and anti-alignment 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…
