Classification and Clustering of arXiv Documents, Sections, and Abstracts, Comparing Encodings of Natural and Mathematical Language [PDF]

open access: yesACM/IEEE Joint Conference on Digital Libraries, 2020
In this paper, we show how selecting and combining encodings of natural and mathematical language affect classification and clustering of documents with mathematical content.

Discretisation Schemes for Level Sets of Planar Gaussian Fields [PDF]

open access: yesCommunications in Mathematical Physics, 2017
Smooth random Gaussian functions play an important role in mathematical physics, a main example being the random plane wave model conjectured by Berry to give a universal description of high-energy eigenfunctions of the Laplacian on generic compact ...

Poisson–Hopf deformations of Lie–Hamilton systems revisited: deformed superposition rules and applications to the oscillator algebra [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2021
The formalism for Poisson–Hopf (PH) deformations of Lie–Hamilton (LH) systems, recently proposed in Ballesteros Á et al (2018 J. Phys. A: Math. Theor. 51 065202), is refined in one of its crucial points concerning applications, namely the obtention of ...

Characterizing covariational reasoning in physics modeling

open access: yesPhysics Education Research Conference Proceedings, 2022
Covariational reasoning—considering how changes in one quantity affect another, related quantity—is a foundation of quantitative modeling in physics. Understanding quantitative models is a learning objective of introductory physics instruction at the ...

Using Math in Physics: 6. Reading the physics in a graph [PDF]

open access: yesThe Physics Teacher, 2023
Learning to use math in physics involves combining (blending) our everyday experiences and the conceptual ideas of physics with symbolic mathematical representations. Graphs are one of the best ways to learn to build the blend.

On Quasi-Energy-Spectra, Pair Correlations of Sequences and Additive Combinatorics [PDF]

open access: yes, 2017
The investigation of the pair correlation statistics of sequences was initially motivated by questions concerning quasi-energy-spectra of quantum systems.

Approximate Unitary t-Designs by Short Random Quantum Circuits Using Nearest-Neighbor and Long-Range Gates [PDF]

open access: yesCommunications in Mathematical Physics, 2018
We prove that $${{\,\textrm{poly}\,}}(t) \cdot n^{1/D}$$ poly ( t ) · n 1 / D -depth local random quantum circuits with two qudit nearest-neighbor gates on a D -dimensional lattice with n qudits are approximate t -designs in various measures.

N-extension of double-graded supersymmetric and superconformal quantum mechanics [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2019
In the recent paper (Bruce and Duplij 2019 (arXiv:1904.06975 [math-ph])), Bruce and Duplij introduced a double-graded version of supersymmetric quantum mechanics (SQM). It is an extension of Lie superalgebraic nature of SQM to a -graded superalgebra.

Ethnoscience of Physics-Math: Calculation of Energy and Wages of Hoeing Farmers in Indonesia

open access: yesJurnal Penelitian Pendidikan IPA, 2023
The purpose of this study is to describe the analysis of farmers' economic concepts, especially the wage system of land hoe labourers. The low wage value of land hoe labourers is a deep concern considering the amount of energy expended by farmers in ...

Partial Differential Equations, Spectral Theory, and Mathematical Physics [PDF]

open access: yesPartial Differential Equations, Spectral Theory, and Mathematical Physics, 2020
We investigate spectral and asymptotic properties of the particular Schrodinger operator (also known as the Bloch-Torrey operator), $-\Delta + i g x$, in infinite periodically perforated domains of $\mathbb R^d$.
