Magnetoplasmons excitations in graphene for filling factors
Yu. A. Bychkov, G. Martinez
In the frame of the Hartree-Fock approximation, the dispersion of magnetoplasmons in Graphene is derived for all types of transitions for filling factors . The optical con…
Evidence for magnetoplasmon character of the cyclotron resonance response of a two-dimensional electron gas
Clément Faugeras, Gérard Martinez, A. Riedel +3
Experimental results on the absolute magneto-transmission of a series of high density, high mobility GaAs quantum wells are compared with the predictions of a recent magnetoplasmon…
Frohlich mass in GaAs-based structures
C. Faugeras, G. Martinez, A. Riedel +3
The Frohlich interaction is one of the main electron-phonon intrinsic interactions in polar materials originating from the coupling of one itinerant electron with the macroscopic e…
Fractional minima in the conductivity of the quantum-Hall-system under microwaves
W. Apel, Yu. A. Bychkov, M. Weyrauch
We analyse theoretically the conductivity of a quantum Hall system exposed to microwave radiation. We find that whenever microwave frequency and cyclotron frequency are commensurat…
Massive Spin Collective Mode in Quantum Hall Ferromagnet
T. Maniv, Yu. A. Bychkov, I. D. Vagner
It is shown that the collective spin rotation of a single Skyrmion in quantum Hall ferromagnet can be regarded as precession of the entire spin texture in the external magnetic fie…
Long Range Coherent Manipulation of Nuclear Spins in Quantum Hall Ferromagnet
T. Maniv, Yu. A. Bychkov, I. D. Vagner
A coherent superposition of many nuclear spin states can be prepared and manipulated via the hyperfine interaction with the electronic spins by varying the Landau level filling fac…
