چکیده
Abstract We study the time-sliced thawed Gaussian propagation method, which was recently proposed for solving time-dependent Schrödinger equation. introduce a triplet of quadrature-based analysis, synthesis and re-initialization operators to give rigorous mathematical formulation method. Further, we derive combined error bounds discretization wave packet transform time-propagation basis functions. Numerical experiments in 1D illustrate theoretical results.

Time-Sliced Thawed Gaussian Propagation Method for Simulations of Quantum Dynamics.
A rigorous method for simulations of quantum dynamics is introduced on the basis of concatenation of semiclassical thawed Gaussian propagation steps. The time-evolving state is represented as a linear superposition of closely overlapping Gaussians that evolve in time according to their characteristic equations of motion, integrated by fourth-order Runge-Kutta or velocity Verlet. The expansion c...
متن کاملAn Improved Error Bound for Gaussian Interpolation
It’s well known that there is a so-called exponential-type error bound for Gaussian interpolation which is the most powerful error bound hitherto. It’s of the form |f(x) − s(x)| ≤ c1(c2d) c3 d ‖f‖h where f and s are the interpolated and interpolating functions respectively, c1, c2, c3 are positive constants, d is the fill-distance which roughly speaking measures the spacing of the data points, ...
متن کاملOn the High-Level Error Bound for Gaussian Interpolation
It’s well-known that there is a very powerful error bound for Gaussians put forward by Madych and Nelson in 1992. It’s of the form|f(x)− s(x)| ≤ (Cd) c d ‖f‖h where C, c are constants, h is the Gaussian function, s is the interpolating function, and d is called fill distance which, roughly speaking, measures the spacing of the points at which interpolation occurs. This error bound gets small ve...
متن کاملError Bound of Certain Gaussian Quadrature Rules for Trigonometric Polynomials
In this paper we give error bound for quadrature rules of Gaussian type for trigonometric polynomials with respect to the weight function w(x) = 1+cosx, x ∈ (−π, π), for 2π-periodic integrand, analytic in a circular domain. Obtained theoretical bound is checked and illustrated on some numerical examples.
متن کاملGaussian Regularized Sliced Inverse Regression
Sliced Inverse Regression (SIR) is an effective method for dimension reduction in high-dimensional regression problems. The original method, however, requires the inversion of the predictors covariance matrix. In case of collinearity between these predictors or small sample sizes compared to the dimension, the inversion is not possible and a regularization technique has to be used. Our approach...
