We theoretically investigate the phase of the de Haas–van Alphen oscillations in topological line-node semimetals. In these semimetals the chemical potential of charge carriers can essentially depend on the magnetic field, ...

We discuss the electron energy spectra and the Berry phases for graphene, a graphite bilayer, and bulk graphite allowing for a small spin-orbit interaction. If an electron orbit in the Brillouin zone surrounds several Dirac ...

We point out that measurements of a phase of the de Haas–van Alphen oscillations can give information on a degeneracy of electron-energy bands in a metal even though this degeneracy occurs far away from its Fermi level. ...
