WebbDynamics of Contact Processes on Simplicial Complexes Description Interacting particle systems on graphs/networks have permeated many sciences in recent decades. The modelling idea is to associate to each vertex/node a state, and then to define a dynamical system on the graph by specifying the interaction between vertices along the edges/links. Webb8 okt. 2024 · Simulating Ising Dynamics In this section we simulate dynamical processes using an Ising model. This requires two elements: a network structure and the dynamics that determine the progression of the system over time. The network structure is encoded as an adjacency matrix in from Equation ( 2 ). 3.1. Network Structures

WebbThe standard Ising model makes unrealistic dynamical predictions, but the Ising model with memory corrects this by using an additional parameter to reflect the tendency for local dynamics to maintain their phase of oscillation. For a 2-simplicial complex structure with N nodes, when predicting the 2-simplexes of a node i, we randomly choose two nodes (e.g., j and k) and calculate the probability Pjk→i, which requires calculating \(\left(\genfrac{}{}{0.0pt}{}{N-1}{2}\right)\) values.

Webb1 mars 1993 · The numerical studies of the pure simplicial quantum gravity in 3d [1-5] have shown that there is a first order phase transition in the model. A continuum limit cannot be taken. This reflects the fact that in three dimensions pure classical gravity has no dynamical degrees of freedom.
