Abstract: A bstractA framework for UV completing particle theories is proposed, based on the worldline formalism, which is equivalent to weighting all sums over histories with a proper-time dependent measure that has a smallest proper-time. We… read more here.

Abstract: The concept of spacetime often conflates mathematical form with physical meaning, obscuring the central role of proper time. This article argues that such ambiguity contributes to persistent difficulties in teaching relativity. Without grounding in proper… read more here.

DOI: 10.1088/1402-4896/adbbe4
Abstract: We introduce a new method to derive solutions of the Dirac equation in external static fields that have a direct connection to classical physics. Using it, we derive new analytic solutions of the Dirac equation… read more here.

Abstract: In attosecond science it is assumed that Wigner-Smith time delays, known from scattering theory, are determined by measuring streaking shifts. Despite their wide use from atoms to solids this has never been proven. Analyzing the… read more here.
