Collective synchronization of classical and quantum oscillators

SY Ha, D Ko, J Park, X Zhang - EMS Surveys in Mathematical Sciences, 2016 - ems.press
Synchronization of weakly coupled oscillators is ubiquitous in biological and chemical
complex systems. Recently, research on collective dynamics of many-body systems has …

Systems of matrix Riccati equations, linear fractional transformations, partial integrability and synchronization

MA Lohe - Journal of Mathematical Physics, 2019 - pubs.aip.org
We partially integrate a system of rectangular matrix Riccati equations which describe the
synchronization behavior of a nonlinear complex system of N globally connected oscillators …

Higher-dimensional generalizations of the Watanabe–Strogatz transform for vector models of synchronization

MA Lohe - Journal of Physics A: Mathematical and Theoretical, 2018 - iopscience.iop.org
Abstract We generalize the Watanabe–Strogatz (WS) transform, which acts on the Kuramoto
model in d= 2 dimensions, to a higher-dimensional vector transform which operates on …

On the semiclassical limit of the Schrödinger-Lohe model and concentration estimates

SY Ha, G Hwang, D Kim - Journal of Mathematical Physics, 2024 - pubs.aip.org
We study the semiclassical limit of quantum synchronization model and concentration
estimates for the resulting limit model. From the Schrödinger-Lohe model, we rigorously …

A model of synchronization over quantum networks

P Antonelli, P Marcati - Journal of Physics A: Mathematical and …, 2017 - iopscience.iop.org
We investigate a non-Abelian generalization of the Kuramoto model proposed by Lohe and
given by N quantum oscillators ('nodes') connected by a quantum network where the …

Critical threshold for synchronizability of high-dimensional Kuramoto oscillators under higher-order interactions

H Huh, D Kim - Chaos: An Interdisciplinary Journal of Nonlinear …, 2024 - pubs.aip.org
We study the asymptotic dynamics of the high-dimensional Kuramoto oscillators on the unit
sphere with two-and three-body interactions that trigger competition between synchrony and …

Asymptotic behavior and stability for the Schrödinger-Lohe model

H Huh, SY Ha, D Kim - Journal of Mathematical Physics, 2018 - pubs.aip.org
The Schrödinger-Lohe (SL) model is an infinite-dimensional non-Abelian generalization of
the Kuramoto model which serves as a prototype model for quantum synchronization. In this …

Complete aggregation of the Lohe tensor model with the same free flow

SY Ha, H Park - Journal of Mathematical Physics, 2020 - pubs.aip.org
The Lohe tensor model is a first-order tensor-valued continuous-time dynamical system for
the aggregation of tensors with the same rank and size. It reduces to the well-known …

On the convergence properties of a heterogeneous multi-agent system on the unit sphere

D Kim - IEEE Transactions on Automatic Control, 2023 - ieeexplore.ieee.org
We establish the convergence of a heterogeneous multiagent system on the unit sphere in
even-dimensional Euclidean space. In this work, we show that all relative distances …

[HTML][HTML] Emergent behaviors of the Schrödinger–Lohe model on cooperative-competitive networks

H Huh, SY Ha, D Kim - Journal of Differential Equations, 2017 - Elsevier
We present several sufficient frameworks leading to the emergent behaviors of the coupled
Schrödinger–Lohe (S–L) model under the same one-body external potential on cooperative …
