Auger-like Relaxation of Inter-Landau-Level Magneto-Plasmon Excitations in the Quantised Hall Regime
S. Dickmann, Y. Levinson
Auger relaxation in 2D strongly correlated electron gas can be represented as an Auger-like process for neutral magnetoplasmon excitations. The case of "dielectric" state with lack…
Collective excitations in a magnetically doped quantized Hall ferromagnet
S. Dickmann, V. Fleurov, K. Kikoin
A theory of collective states in a magnetically quantized two-dimensional electron gas (2DEG) with half-filled Landau level (quantized Hall ferromagnet) in the presence of magnetic…
The Cyclotron Spin-Flip Mode as the Lowest-Energy Excitation of Unpolarized Integer Quantum Hall States
L. V. Kulik, I. V. Kukushkin, S. Dickmann +6
The cyclotron spin-flip modes of spin unpolarized integer quantum Hall states () have been studied with inelastic light scattering. The energy of these modes is significantl…
Zero-Momentum Cyclotron Spin-Flip Mode in a Spin-Unpolarized Quantum Hall System
S. Dickmann, I. V. Kukushkin
We report on a study of the zero-momentum cyclotron spin-flip excitation in the V=2 quantum Hall regime. Using the excitonic representation the excitation energy is calculated up t…
Bound States in a Quantized Hall Ferromagnet
S. Dickmann
We report on a study of the quasielectron-quasihole and skyrmion-antiskyrmion bound states in the quantum Hall regime. The short range attraction potential is assumed to be d…
Goldstone-Mode Relaxation in a Quantized Hall Ferromagnet in the Presence of Smooth Random Potential
S. Dickmann
We discuss the spin relaxation of a strongly correlated two-dimensional (2D) electron gas (2DEG) in the quantized Hall regime when the filling factor is close to an odd-integer. As…
