Entanglement of higher-derivative oscillators in holographic systems

open access: yesNuclear Physics B, 2017
We study the quantum entanglement of coupled Pais–Uhlenbeck oscillators using the formalism of thermo-field dynamics. The entanglement entropy is computed for the specific cases of two and a ring of N coupled Pais–Uhlenbeck oscillators of fourth order ...

Non-Boolean Associative Processing: Circuits, System Architecture, and Algorithms

open access: yesIEEE Journal on Exploratory Solid-State Computational Devices and Circuits, 2015
We present the design and the performance of a hierarchical associative memory (AM) based on phase locking of coupled oscillators used for pattern recognition.

Frequency-amplitude correlation inducing first-order phase transition in coupled oscillators

open access: yesNew Journal of Physics, 2022
The first-order phase transitions in coupled oscillators have been widely studied because of their discontinuity and irreversibility. In previous research, the designed coupling mechanisms between each pair of oscillators can cause the first-order phase ...

Coupled-Oscillators [PDF]

open access: yesInternational Astronomical Union Colloquium, 1993
AbstractModal coupling oscillation models for the stellar radial pulsation and coupled-oscillators are reviewed. Coupled-oscillators with the second-order and third-order terms seemed to behave non-systematically. Using the equation by Schwarzschild and Savedoff (1949) with the dissipation term of van del Pol’s type which is third-order, we demonstrate

Collective synchronization of dissipatively-coupled noise-activated processes

open access: yesNew Journal of Physics, 2023
We study the stochastic dynamics of an arbitrary number of noise-activated cyclic processes, or oscillators, that are all coupled to each other via a dissipative coupling.

Markovian evolution of strongly coupled harmonic oscillators [PDF]

open access: yes, 2014
We investigate how to model Markovian evolution of coupled harmonic oscillators, each of them interacting with a local environment. When the coupling between the oscillators is weak, dissipation may be modeled using local Lindblad terms for each of the ...

Band Gaps and Vibration Attenuation Characteristics Analysis in Homogeneous Beam Coupled With Periodic Oscillators Based on the Method of Reverberation-Ray Matrix

open access: yesFrontiers in Materials, 2022
A periodic beam-oscillators coupling system is proposed as a physical model in this paper for analyzing the dynamic characteristics of periodic support beams and low-frequency flexural wave vibration of slender stiffened plate structures.

Independent Component Analysis of Spatiotemporal Chaos [PDF]

open access: yes, 2005
Two types of spatiotemporal chaos exhibited by ensembles of coupled nonlinear oscillators are analyzed using independent component analysis (ICA). For diffusively coupled complex Ginzburg-Landau oscillators that exhibit smooth amplitude patterns, ICA ...

Physical Implementation of Coherently Coupled Oscillator Networks

open access: yesIEEE Journal on Exploratory Solid-State Computational Devices and Circuits, 2015
We present a combined experimental and simulation study of the physical implementation of coherently coupled oscillator networks composed of spin-torque oscillators (STOs). Based on published works and on our recent experiments, we review the behavior of

Prime factorization using coupled oscillators with positive feedback

open access: yesAIP Advances, 2022
Prime factorization is a procedure of determining the prime factors of a given number N that requires super-polynomial time for conventional digital computers.
