Sparse identification of quantum Hamiltonian dynamics via quantum circuit learning
Yusei Tateyama, Yuzuru Kato
Sparse identification of nonlinear dynamics (SINDy) is a data-driven framework for estimating classical nonlinear dynamical systems from time-series data. In this approach, system…
Equivalence of additive and parametric pinning control protocols for systems of weakly coupled oscillators
Riccardo Muolo, Yuzuru Kato
Controlling the behavior of nonlinear systems on networks is a paramount task in control theory, in particular the control of synchronization, given its vast applicability. In this…
Synchronization of Dirac-Bianconi driven oscillators
Riccardo Muolo, Iván León, Yuzuru Kato +1
In dynamical systems on networks, one assigns the dynamics to nodes, which are then coupled via links. This approach does not account for group interactions and dynamics on links a…
Quantum spin van der Pol oscillator -- a spin-based limit-cycle oscillator exhibiting quantum synchronization
Yuzuru Kato, Hiroya Nakao
We introduce a quantum spin van der Pol (vdP) oscillator as a prototypical model of quantum spinbased limit-cycle oscillators, which coincides with the quantum optical vdP oscillat…
Data-driven phase control for limit-cycle oscillators under partial observation
Koichiro Yawata, Norihisa Namura, Yuzuru Kato +1
Controlling rhythmic systems, typically modeled as limit-cycle oscillators, is an important subject in real-world problems. Phase reduction theory, which simplifies the multidimens…
Quantum asymptotic amplitude for quantum oscillatory systems from the Koopman operator viewpoint
Yuzuru Kato
We have recently proposed a fully quantum-mechanical definition of the asymptotic phase for quantum nonlinear oscillators, which is also applicable in the strong quantum regime [Ka…
