Preponderant Orbital Polarization in Relativistic Magnetovortical Matter

TL;DR

This paper demonstrates that in relativistic magnetovortical matter, orbital effects dominate thermodynamics and lead to observable sign changes in charge and current, revealing a new aspect of matter under combined rotation and magnetic fields.

Contribution

It shows that orbital contributions outweigh spin effects in thermodynamics of Dirac fermions under rotation and magnetic fields, highlighting a novel preponderance in magnetovortical matter.

Findings

Orbital effects dominate over spin contributions in thermodynamics.

Sign inversion of induced charge and current observed.

Experimental test proposed via angular momentum polarization flip.

Abstract

We establish thermodynamic stability and gauge invariance in the magnetovortical matter of Dirac fermions under the coexistent rotation and strong magnetic field. The corresponding partition function reveals that the orbital contribution to bulk thermodynamics preponderates over the conventional contribution from anomaly-related spin effects. This orbital preponderance macroscopically manifests itself in the sign inversion of the induced charge and current in the magnetovortical matter, and can be tested experimentally as the flip of the angular momentum polarization of magnetovortical matter when the magnetic field strength is increased.
