Are Superfluid Vortices in Pulsars Violating the Weak Equivalence Principle?

TL;DR

This paper explores the possibility that irregularities in pulsar timing, such as glitches and noise, may indicate a violation of the weak equivalence principle by vortices in the superfluid core of neutron stars.

Contribution

It proposes a novel link between pulsar timing irregularities and potential violations of fundamental physics principles in superfluid vortices.

Findings

Timing irregularities could be evidence of weak equivalence principle violation.

Superfluid vortex dynamics may influence pulsar rotational behavior.

Theoretical implications for neutron star physics and fundamental physics.

Abstract

In the present paper we argue that timing irregularities in pulsars, like glitches and timing noise, could be associated with the violation of the weak equivalence principle for vortices in the superfluid core of rotating neutron stars.
