Scattering amplitudes for all masses and spins

open access: yesJournal of High Energy Physics, 2021
We introduce a formalism for describing four-dimensional scattering amplitudes for particles of any mass and spin. This naturally extends the familiar spinor-helicity formalism for massless particles to one where these variables carry an extra SU(2 ...

An Optimality Summary: Secret Key Agreement with Physical Unclonable Functions

open access: yesEntropy, 2020
We address security and privacy problems for digital devices and biometrics from an information-theoretic optimality perspective to conduct authentication, message encryption/decryption, identification or secure and private computations by using a secret

Topics in computational algebraic number theory [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
We describe practical algorithms from computational algebraic number theory, with applications to class field theory. These include basic arithmetic, approximation and uniformizers, discrete logarithms and computation of class fields. All algorithms have been implemented in the Pari/Gp system.

Cyclotomic Classes in a Product of Finite Abelian Groups and Applications

open access: yesJournal of Mathematics
Cyclotomic classes of finite abelian groups have been extensively investigated for many decades, largely because of their nice algebraic structure and the breadth of their theoretical and practical applications.

On the Girth of Tanner QC-LDPC Cycle Codes: An Algebraic Number Theory Approach

open access: yesAxioms
Tanner quasi-cyclic low-density parity-check (QC-LDPC) codes form an important family of structured LDPC codes with favorable girth properties. This paper studies the girth of Tanner (2, L)-regular QC-LDPC codes (referred to as Tanner QC-LDPC cycle codes)

Nemo/Hecke [PDF]

open access: yesProceedings of the 2017 ACM International Symposium on Symbolic and Algebraic Computation, 2017
We introduce two new packages, Nemo and Hecke, written in the Julia programming language for computer algebra and number theory. We demonstrate that high performance generic algorithms can be implemented in Julia, without the need to resort to a low-level C implementation.

A new boundary element sensitivity analysis for generalized thermoelastic three-phase-lag model of anisotropic materials

open access: yesOpen Mathematics
This article presents a novel formulation of the boundary element method (BEM) for sensitivity analysis of the generalized thermoelastic three-phase-lag (TPL) model with directional dependence for anisotropic materials.
