Collective modes of doped graphene and a standard 2DEG in a strong magnetic field: linear magneto-plasmons versus magneto-excitons
R. Roldan, J. -N. Fuchs, M. O. Goerbig
A doped graphene layer in the integer quantum Hall regime reveals a highly unusual particle-hole excitation spectrum, which is calculated from the dynamical polarizability in the r…

Interplay of metamagnetic and structural transitions in CaSrRuO
Rafael Roldan, Andreas Ruegg, Manfred Sigrist
Metamagnetism in layered ruthenates has been interpreted as a novel kind of quantum critical behavior. In an external magnetic field, CaSrRuO undergoes a metamagnet…
