A quantum algorithm for linear autonomous differential equations via Padé approximation [PDF]

open access: yesQuantum
We propose a novel quantum algorithm for solving linear autonomous ordinary differential equations (ODEs) using the Padé approximation. For linear autonomous ODEs, the discretized solution can be represented by a product of matrix exponentials.

Computation of Analytical Zoom Locus Using Padé Approximation

open access: yesMathematics, 2020
When the number of lens groups is large, the zoom locus becomes complicated and thus cannot be determined by analytical means. By the conventional calculation method, it is possible to calculate the zoom locus only when a specific lens group is fixed or ...

Multivariate Padé Approximation for Solving Nonlinear Partial Differential Equations of Fractional Order

open access: yesAbstract and Applied Analysis, 2013
Two tecHniques were implemented, the Adomian decomposition method (ADM) and multivariate Padé approximation (MPA), for solving nonlinear partial differential equations of fractional order. The fractional derivatives are described in Caputo sense.

Non-commutative Hermite–Padé approximation and integrability [PDF]

open access: yesLetters in Mathematical Physics, 2022
We introduce and solve the non-commutative version of the Hermite–Padé type I approximation problem. Its solution, expressed by quasideterminants, leads in a natural way to a subclass of solutions of the non-commutative Hirota (discrete Kadomtsev ...

Accurate Frequency Estimation With Fewer DFT Interpolations Based on Padé Approximation [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2021
Frequency estimation is a fundamental problem in many areas. The well-known A&M and its variant estimators have established an estimation framework by iteratively interpolating the discrete Fourier transform (DFT) coefficients.

Hermite-Padé approximation and integrability [PDF]

open access: yesJournal of Approximation Theory, 2022
We show that solution to the Hermite-Pad\'{e} type I approximation problem leads in a natural way to a subclass of solutions of the Hirota (discrete Kadomtsev-Petviashvili) system and of its adjoint linear problem.

Robust analytic continuation combining the advantages of the sparse modeling approach and the Padé approximation [PDF]

open access: yesPhysical review B, 2021
Analytic continuation (AC) from the imaginary-time Green’s function to the spectral function is a crucial process for numerical studies of the dynamical properties of quantum many-body systems. This process, however, is an ill-posed problem; that is, the

Fast Identification of Micro-Health Parameters for Retired Batteries Based on a Simplified P2D Model by Using Padé Approximation

open access: yesBatteries, 2023
Better performance consistency of regrouped batteries retired from electric vehicles can guarantee the residual value maximized, which greatly improves the second-use application economy of retired batteries.
