Nonlinear eigenvalue problems arise in a variety of science and engineering applications,
and in the past ten years there have been numerous breakthroughs in the development of …

A review is presented of the most effective methods for the computation of Sommerfeld
integral tails. Such integrals, which are often oscillatory, singular and divergent, commonly …

We design a quantum algorithm for ground state preparation in the early fault tolerant
regime. As a Monte Carlo style quantum algorithm, our method features a Lindbladian …

Koopman operators globally linearize nonlinear dynamical systems and their spectral
information is a powerful tool for the analysis and decomposition of nonlinear dynamical …

Koopman operators are infinite‐dimensional operators that globally linearize nonlinear
dynamical systems, making their spectral information valuable for understanding dynamics …

A bstract We explore whether the axion which solves the strong CP problem can naturally be
much lighter than the canonical QCD axion. The\({Z} _ {\mathcal {N}}\) symmetry proposed …

MATLAB® 1 is an interactive system for numerical computation. Numerical analyst Cleve
Moler wrote the initial Fortran version of MATLAB in the late 1970s as a teaching aid. It …

Directional amplification, in which signals are selectively amplified depending on their
propagation direction, has attracted much attention as key resource for applications …

We present a biorthogonal approach for modeling the response of localized electromagnetic
resonators using quasinormal modes, which represent the natural, dissipative eigenmodes …

The Mittag-Leffler (ML) function plays a fundamental role in fractional calculus but very few
methods are available for its numerical evaluation. In this work we present a method for the …
