Light scattering from a periodically modulated two dimensional electron gas with partially filled Landau levels
Arne Brataas, C. Zhang, K. A. Chao
We study light scattering from a periodically modulated two dimensional electron gas in a perpendicular magnetic field. If a subband is partially filled, the imaginary part of the…
Spin-density and charge-density excitations in quantum wires
Arne Brataas, A. G. Mal'hukov, Christoph Steinebach +2
We study an interacting electron gas in a quantum wire within the Hartree-Fock random phase approximation. Vertex corrections to the electron spin polarizability due to the electro…
The effects of compressible and incompressible states on the FIR-absorption of quantum wires and dots in a magnetic field
Vidar Gudmundsson, Arne Brataas, Christoph Steinebach +3
We investigate the effects of compressible and incompressible states on the FIR-absorption of quantum wires and dots in a homogeneous perpendicular magnetic field. The electron-ele…
The evolution of Bernstein modes in quantum wires with increasing deviation from parabolic confinement
Arne Brataas, Vidar Gudmundsson, A. G. Mal'shukov +1
We investigate the evolution of the interaction of the magnetoplasmon resonance with the harmonics of the cyclotron resonance as the confinement of an electron gas in a quantum wir…
