Cyclotron Motion in the Vicinity of a Lifshitz Transition in Graphite
Cyclotron Motion in the Vicinity of a Lifshitz Transition in Graphite
Graphite, a model (semi)metal with trigonally warped bands, is investigated with a magnetoabsorption experiment and viewed as an electronic system in the vicinity of the Lifshitz transition. A characteristic pattern of up to 20 cyclotron resonance harmonics has been observed. This large number of resonances, their relative strengths and characteristic …
