# Role of Landau-Rabi quantization of electron motion on the crust of magnetars within the nuclear energy density functional theory

## TL;DR

This paper investigates how ultra-strong magnetic fields influence the crust of magnetars by affecting electron motion through Landau-Rabi quantization, using nuclear energy density functional theory for a unified description.

## Contribution

It provides a novel, unified theoretical framework to analyze the effects of magnetic fields on neutron star crusts considering Landau-Rabi quantization.

## Key findings

- Magnetic fields significantly alter the crust's equation of state.
- Electron composition in the crust is affected by Landau-Rabi quantization.
- The study offers insights into the crustal structure of magnetars under extreme magnetic conditions.

## Abstract

Magnetic fields of order $10^{15}$ G have been measured at the surface of some neutron stars, and much stronger magnetic fields are expected to be present in the solid region beneath the surface. The effects of the magnetic field on the equation of state and on the composition of the crust due to Landau-Rabi quantization of electron motion are studied. Both the outer and inner crustal regions are described in a unified and consistent way within the nuclear-energy density functional theory.
