Electronic properties of graphite in tilted magnetic fields

TL;DR

This paper investigates how tilted magnetic fields affect the electronic structure of Bernal-stacked graphite, revealing that in-plane magnetic components cause Landau level splitting at the H point, with potential experimental implications.

Contribution

It introduces a tight-binding model analysis of graphite under tilted magnetic fields, highlighting the differential effects at K and H points and predicting observable Landau level splitting.

Findings

Negligible effect of in-plane field at K point

Linear growth of Landau level splitting at H point

Potential for experimental detection of splitting

Abstract

The minimal nearest-neighbor tight-binding model with the Peierls substitution is employed to describe the electronic structure of Bernal-stacked graphite subject to tilted magnetic fields. We show that while the presence of the in-plane component of the magnetic field has a negligible effect on the Landau level structure at the K point of the graphite Brillouin zone, at the H point it leads to the experimentally observable splitting of Landau levels which grows approximately linearly with the in-plane field intensity.
