arises from the continuum limit of the lattice thermodynamic Kuramoto (TK) model [17]. The …

[PDF][PDF] Complete solvability of the inertial spin model with an averaged spin

H Huh, D Kim - Quarterly of Applied Mathematics, 2022 - researchgate.net
We study the inertial spin model which consists of two variables: velocity as a mechanical
observable and spin as an internal variable. In this paper, we slightly modified the original …

Cooperative Behaviors of Thermodynamic Kuramoto Model Under External Fields

Y Shao, Y **, A Hu, S Yang - … Journal of Control, Automation and Systems, 2022 - Springer
Each oscillator, subject to external fields, interacts with all the other oscillators. Therefore,
the original thermodynamic Kuramoto model (TK model) is used to study the influence of …
