Abstract
Neutron-star magnetospheres are structured by very intense magnetic fields extending from 100 to traveled by very energetic electrons and positrons with Lorentz factors up to . In this context, particles are forced to travel almost along the magnetic field with very small gyromotion, potentially reaching the quantified regime. We describe the state of Dirac particles in a locally uniform, constant, and curved magnetic field in the approximation that the Larmor radius is very small compared to the radius of curvature of the magnetic field lines. We obtain a result that admits the usual relativistic Landau states as a limit of null curvature. We will describe the radiation of these states, which we call quantum curvature or synchrocurvature radiation, in an upcoming paper.
