Truncation error analysis for the piecewise parabolic method

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This work provides a theoretical error analysis of the well‐established piecewise parabolic method for unforced linear advection problems with non‐constant velocity. Numerical results confirm that merely first‐order accuracy is obtained for deformational flows.

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, EarlyView.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Exposing and Challenging “Grit” in Physics Education

Science Education, EarlyView.
ABSTRACT In STEM education, grit is increasingly the focus of research, with scholars and educators seeking to develop and test interventions that will enhance persistence. As part of the special issue Centering Affect and Emotion Toward Justice and Dignity in Science Education, in this paper, we use interviews with 12 white physics faculty to show ...

Spin and Maximal Acceleration

Galaxies, 2017
We study the spin current tensor of a Dirac particle at accelerations close to the upper limit introduced by Caianiello. Continual interchange between particle spin and angular momentum is possible only when the acceleration is time-dependent.

From the Politics of Affect to the Politics of Being Affected By/With Others: A Commentary on the Special Issue

Science Education, EarlyView.
ABSTRACT We live in times of crises, genocides, and massive destruction of both the natural and social habitat, where justice‐centered socio‐political visions of the future enacted in the present are urgently needed. Hence, the special issue Centering Affect and Emotion Toward Justice and Dignity in Science Education could not be more timely and needed.
