Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Identification of Nonlinear Circuits as Port-Hamiltonian Systems

2021 24th International Conference on Digital Audio Effects (DAFx), 2021
This paper addresses identification of nonlinear circuits for power-balanced virtual analog modeling and simulation. The proposed method combines a port-Hamiltonian system formulation with kernel-based methods to retrieve model laws from measurements.This combination allows for the estimated model to retain physical properties that are crucial for the ...

Infinite-Dimensional Port-Hamiltonian Systems

, 2009
This chapter presents the formulation of distributed parameter systems in terms of port-Hamiltonian system. In the first part it is shown, for different examples of physical systems defined on one-dimensional spatial domains, how the Dirac structure and

Self-organization in pedestrian dynamics: a stochastic port-Hamiltonian approach

Acta Polytechnica CTU Proceedings
Understanding pedestrian crowds as complex systems reveals how simple individual interactions yield rich collective behaviors. In this study, we adopt an energy-based modeling framework – port-Hamiltonian (pH) systems – to analyze a minimalist variant ...

A Scalable and Resource‐Efficient Pipelined p‐Computer for Probabilistic Ising Machines

Advanced Intelligent Systems, EarlyView.
(a) Block diagram of the portfolio optimization problem: given M assets, the goal is to determine the optimal weights w that maximize the expected return (based on the mean historical assets return u), while minimizing the risk, quantified by the assets covariance matrix S.

Lumped Approximation of a Transmission Line with an Alternative Geometric Discretization [PDF]

, 2004
An electromagnetic one-dimensional transmission line represented in a distributed port-Hamiltonian form is lumped into a chain of subsystems which preserve the port-Hamiltonian structure with inputs and outputs in collocated form.

Memristive port-Hamiltonian Systems [PDF]

, 2010
The port-Hamiltonian modelling framework is extended to a class of systems containing memristive elements and phenomena. First, the concept of memristance is generalised to the same generic level as the port-Hamiltonian framework.

A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators

Laser &Photonics Reviews, EarlyView.
ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.

Three‐Dimensional Optical Characterization of Magnetostrictive Deformation in Magnomechanical Systems

Laser &Photonics Reviews, EarlyView.
An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.
