Covid-19 epidemic under the K-quarantine model: Network approach
K. Choi, Hoyun Choi, B. Kahng
The Covid-19 pandemic is ongoing worldwide, and the damage it has caused is unprecedented. For prevention, South Korea has adopted a local quarantine strategy rather than a global…
Absorbing phase transition with a continuously varying exponent in a quantum contact process: a neural network approach
Minjae Jo, Jongshin Lee, K. Choi +1
Phase transitions in dissipative quantum systems are intriguing because they are induced by the interplay between coherent quantum and incoherent classical fluctuations. Here, we i…
Two golden times in two-step contagion models
Wonjun Choi, Deokjae Lee, J. Kertész +1
The two-step contagion model is a simple toy model for understanding pandemic outbreaks that occur in the real world. The model takes into account that a susceptible person either…
Scale-free random branching tree in supercritical phase
D. -S. Lee, J. S. Kim, B. Kahng +1
We study the size and the lifetime distributions of scale-free random branching tree in which branches are generated from a node at each time step with probability $q_k\sim k^{…
