A novel iterative method to approximate structured singular values

, 2016
A novel method for approximating structured singular values (also known as mu-values) is proposed and investigated. These quantities constitute an important tool in the stability analysis of uncertain linear control systems as well as in structured ...

Spectral Decomposition of Chemical Semantics for Activity Cliffs‐Aware Molecular Property Prediction

Advanced Science, EarlyView.
PrismNet mimics chemical intuition by functioning as a computational prism, refracting molecular graphs into complementary semantic views and spectral frequencies. This dual‐decomposition strategy effectively captures both global topologies and subtle “activity cliff” perturbations.

Eigenvalue problems for perturbed p‐Laplacians

AIP Conference Proceedings, 2010
This main subject of this paper is the problem of the existence of eigenvectors and a dispersion analysis of a class of multi parameter eiegen‐value problems for perturbed p‐Laplacians. This paper is particularly, devoted to the problems of describing the eigen‐parameters.

Exact solution of the relationship between the eigenvalue discreteness and the behavior of eigenstates in Su–Schrieffer–Heeger lattices

New Journal of Physics
The interplay between eigenvalue discreteness and eigenstate localization is a fundamental characteristic of one-dimensional Su–Schrieffer–Heeger (SSH) lattices.

Second Order Eigensensitivities of Singularly Perturbed Systems

Journal of King Saud University: Engineering Sciences, 1994
In this paper, second order eigenvalue sensitivities are derived with respect to the singular perturbation parameter whose variation changes the reduced system order.

Semiconducting THO‐C3N Monolayers for Ultrahigh Anisotropic Carrier Mobility

Advanced Science, EarlyView.
A precise site‐specific N‐doping strategy that drives a secondary electronic transition in net W is proposed, enabling the electronic properties transition from metal to Dirac semimetal and ultimately to semiconductor. The obtained THO‐C3N‐2 and THO‐C3N‐3 semiconductors exhibit high carrier mobilities and pronounced mobility anisotropy, with THO‐C3N‐2 ...

Perturbations of symmetric eigenvalue problems

Applied Mathematics Letters, 2002
The paper is concerned with the existence of multiple solutions \((u,\lambda)\in H^1_0(\Omega)\times\mathbb{R}\) of the elliptic eigenvalue problem \[ -\Delta u= \lambda(f(x,u)+\varepsilon g(x,u))\text{ in }\Omega,\;u|_{\partial\Omega}= 0,\;\int_\Omega|\nabla u|^2 dx=r^2,\tag{1} \] where \(f\) and \(g\) are continuous functions from \(\overline\Omega ...

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues

Advanced Science, EarlyView.
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Jacobians and rank 1 perturbations relating to unitary Hessenberg matrices [PDF]

, 2005
In a recent work Killip and Nenciu gave random recurrences for the characteristic polynomials of certain unitary and real orthogonal upper Hessenberg matrices. The corresponding eigenvalue p.d.f.'s are beta-generalizations of the classical groups.
