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 …

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 …

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 …

Collective Dynamics of Lohe type aggregation models

SY Ha, D Kim - Modeling and Simulation for Collective Dynamics, 2023 - World Scientific
In this chapter, we review state-of-the-art results on the collective behaviors for Lohe type
first-order aggregation models. Collective behaviors of classical and quantum many-body …

Schrödinger-Lohe type models of quantum synchronization with nonidentical oscillators

P Antonelli, DN Reynolds - Journal of Differential Equations, 2023 - Elsevier
We study the asymptotic emergent dynamics of two models that can be thought of as
extensions of the well known Schrödinger-Lohe model for quantum synchronization. More …

Collective synchronization of the multi-component Gross–Pitaevskii–Lohe system

W Bao, SY Ha, D Kim, Q Tang - Physica D: Nonlinear Phenomena, 2019 - Elsevier
In this paper, we propose a multi-component Gross–Pitaevskii–Lohe (GPL for brevity)
system in which quantum units interact with each other such that collective behaviors can …

[HTML][HTML] On the Schrödinger–Lohe Hierarchy for Aggregation and Its Emergent Dynamics

SY Ha, H Park - Journal of Statistical Physics, 2020 - Springer
The Lohe hierarchy is a hierarchy of finite-dimensional aggregation models consisting of the
Kuramoto model, the complex Lohe sphere model, the Lohe matrix model and the Lohe …

Two-point correlation function and its applications to the Schrödinger-Lohe type models

SY Ha, G Hwang, D Kim - Quarterly of Applied Mathematics, 2022 - ams.org
We study the asymptotic emergent dynamics and the continuum limit for the Schrödinger-
Lohe (SL) model and semi-discrete SL model. For the SL model, emergent dynamics has …

Emergence of synchronous behaviors for the Schrödinger–Lohe model with frustration

SY Ha, D Kim - Nonlinearity, 2019 - iopscience.iop.org
We introduce the Schrödinger–Lohe model (S–L) with interaction frustration which is a toy
model for quantum synchronization, and study its emergent collective dynamics. Our …

Solitons in complex systems of chiral fields with Kuramoto interactions

MA Lohe - Chaos: An Interdisciplinary Journal of Nonlinear …, 2021 - pubs.aip.org
We construct a complex system of N chiral fields, each regarded as a node or a constituent
of a complex field-theoretic system, which interact by means of chirally invariant potentials …
