Regularization of Divergent Power Sums via Fractional Extension of Differential Generators

Eric A. Galapon

We reconsider the problem of regularizing the divergent series for , and offer a regularization prescription that yields the Riema…

Contour Integral Representations of Finite-part Integrals with Logarithmic Singularities

Reynaldo P. Ylanan, Eric A. Galapon

The integral diverges for , where is the order of the first non-vanishing derivative of at the origin. With…

Dirac delta-convergence of free-motion time-of-arrival eigenfunctions

John Jaykel P. Magadan, Eric A. Galapon

Previous numerical analyses on the Aharonov-Bohm (AB) operator representing the quantum time-of-arrival (TOA) observable for the free particle have indicated that its eigenfunction…

Canonical pairs in finite-dimensional Hilbert space

Ralph Adrian E. Farrales, Eric A. Galapon

A pair of Hermitian operators is canonical if they satisfy the canonical commutation relation. It has been believed that no such canonical pair exists in finite-dimensional Hilbert…

Asymptotic evaluation of the Sinc transform of entire exponential type function resulting to exact polynomial asymptotic behavior

Nathalie Liezel R. Rojas, Eric A. Galapon

We consider the asymptotic evaluation of the integral transform of an exponential type function of type , for larg…

Instantaneous tunneling time within the theory of time-of-arrival operators

Philip Caesar Flores, Dean Alvin Pablico, Eric Galapon

It has been shown in Phys. Rev. Lett., 108 170402 (2012) (https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.108.170402), that quantum tunneling is instantaneous using a tim…
