Stochastization of long living spin-cyclotron excitations in a spin-unpolarised quantum Hall system
S. Dickmann, B. D. Kaysin
In the present study we address the kinetics of long-lived excitations at zero temperature in an electronic quantum Hall system with filling factor . The initial coherent stat…
Damping via the hyperfine interaction of a spin-rotation mode in a two-dimensional strongly magnetized electron plasma
S. Dickmann
We address damping of a Goldstone spin-rotation mode emerging in a quantum Hall ferromagnet due to laser pulse excitation. Recent experimental data show that the attenuation mechan…
Spin-flip excitations and Stoner ferromagnetism in a strongly correlated quantum Hall system
S. Dickmann, B. D. Kaysin
Spin-flip excitations in a quantum Hall electron system at fixed filling factor nu=2 are modelled and studied under conditions of a strong Coulomb interaction when the `Landau leve…
Optical absorption in incoherent and coherent states of a quantum Hall system
S. Dickmann
In connection with recent studies of extremely long-living spin-cyclotron excitations (actually magneto-excitons) in a quantum Hall electron gas, we discuss contribution to the lig…
Spin-rotation mode in a quantum Hall ferromagnet
S. Dickmann
A spin-rotation mode emerging in a quantum Hall ferromagnet due to laser pulse excitation is studied. This state, macroscopically representing a rotation of the entire electron spi…
Magneto-phonon resonance in photoluminescence excitation spectra of magneto-excitons in GaAs/AlGaAs Superlattices
S. Dickmann, A. I. Tartakovskii, V. B. Timofeev +4
Strong increase in the intensity of the peaks of excited magneto-exciton (ME) states in the photoluminescence excitation (PLE) spectra recorded for the ground heavy-hole magneto-ex…
