Fast renormalizing the structures and dynamics of ultra-large systems via random renormalization group
Yang Tian, Yizhou Xu, Pei Sun
Criticality and symmetry, studied by the renormalization groups, lie at the heart of modern physics theories of matters and complex systems. However, surveying these properties wit…
Simplex path integral and simplex renormalization group for high-order interactions
Aohua Cheng, Yunhui Xu, Pei Sun +1
Modern theories of phase transitions and scale-invariance are rooted in path integral formulation and renormalization group (RG). Despite the applicability of these approaches on s…
Laplacian dynamics of convergent and divergent swarm behaviors
Yang Tian, Yunhui Xu, Pei Sun
Swarming phenomena are ubiquitous in various physical, biological, and social systems, where simple local interactions between individual units lead to complex global patterns. A c…
Thermodynamics of percolation in interacting systems
Yizhou Xu, Pei Sun, Yang Tian
Interacting systems can be studied as the networks where nodes are system units and edges denote correlated interactions. Although percolation on network is a unified way to model…
A unified theory of information transfer and causal relation
Yang Tian, Hedong Hou, Yaoyuan Wang +2
Information transfer between coupled stochastic dynamics, measured by transfer entropy and information flow, is suggested as a physical process underlying the causal relation of sy…
Thermodynamics of Encoding and Encoders
Yang Tian, Pei Sun
Non-isolated systems have diverse coupling relations with the external environment. These relations generate complex thermodynamics and information transmission between the system…
