Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, EarlyView.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Cauchy Problem of the non-self-adjoint Gauss-Laguerre semigroups and uniform bounds of generalized Laguerre polynomials

, 2016
We propose a new approach to construct the eigenvalue expansion in a weighted Hilbert space of the solution to the Cauchy problem associated to Gauss-Laguerre invariant Markov semigroups that we introduce. Their generators turn out to be natural non-self-

Parametric Excitation of a Ferrimagnetic Sphere Resonator

Advanced Quantum Technologies, EarlyView.
The hypothesis that disentanglement spontaneously occurs in quantum systems is experimentally tested using a ferromagnetic resonator. Predictions derived from the hypothesis, and from an alternative theoretical model, are compared with the measured response of the resonator to an externally applied driving.

Weak Symplectic Functional Analysis and General Spectral Flow Formula

, 2004
We consider a continuous curve of self-adjoint Fredholm extensions of a curve of closed symmetric operators with fixed minimal domain $D_m$ and fixed {\it intermediate} domain $D_W$.

Robust Control Design and Analysis Based on Lifting Linearization of Nonlinear Systems Under Uncertain Initial Conditions

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents a robust control synthesis and analysis framework for nonlinear systems with uncertain initial conditions. First, a deep learning‐based lifting approach is proposed to approximate nonlinear dynamical systems with linear parameter‐varying (LPV) state‐space models in higher‐dimensional spaces while simultaneously ...

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

Small, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Fault diagnosis method of a cascaded H‐bridge inverter based on a multisource adaptive fusion CNN‐transformer

IET Power Electronics, EarlyView.
The multisource adaptive fusion CNN‐transformer method proposed in this study can provide theoretical and technical support for fault diagnosis of high‐voltage MCHBI. It has a promising potential for engineering applications. Abstract In high‐voltage applications, the number of cascaded H‐bridge inverter units is large, the failure probability ...

The (Re)Design of Ecosystems to Face Grand Challenges—Toward the Management of Creative Evolution

Creativity and Innovation Management, EarlyView.
ABSTRACT Today's grand challenges have to be discussed comprehensively, addressing the current design and the redesign of social and economic ecosystems. Tackling grand challenges requires a step into the unknown, a situation that is well‐characterised today as strongly different in nature from uncertainty and requires specific types of management ...
