Dynamical Conductivity of Disordered Quantum Hall Stripes
Mei-Rong Li, H. A. Fertig, R. Cote +1
We present a detailed theory for finite-frequency conductivities Re of quantum Hall stripes, which form at Landau level close to half filling, in the presenc…
Hole maximum density droplets of an antidot in strong magnetic fields
N. Y. Hwang, S. -R. Eric Yang, H. -S. Sim +1
We investigate a quantum antidot in the integer quantum Hall regime (the filling factor is two) by using a Hartree-Fock approach and by transforming the electron antidot into a sys…
Elementary Excitations in One-Dimensional Electromechanical Systems; Transport with Back-Reaction
Kang-Hun Ahn, Hangmo Yi
Using an exactly solvable model, we study low-energy properties of a one-dimensional spinless electron fluid contained in a quantum-mechanically moving wire located in a static mag…
Quantum Depinning Transition of Quantum Hall Stripes
Meirong Li, H. A. Fertig, R. Cote +1
We examine the effect of disorder on the electromagnetic response of quantum Hall stripes using an effective elastic theory to describe their low-energy dynamics, and replicas and…
Quantum Dissipative Dynamics of the Magnetic Resonance Force Microscope in the Single-Spin Detection Limit
Hanno Gassmann, Mahn-Soo Choi, Hangmo Yi +1
We study a model of a magnetic resonance force microscope (MRFM) based on the cyclic adiabatic inversion technique as a high-resolution tool to detect single electron spins. We inv…
Coulomb Blockade and Kondo Effect in a Quantum Hall Antidot
H. -S. Sim, M. Kataoka, Hangmo Yi +3
We propose a general capacitive model for an antidot, which has two localized edge states with different spins in the quantum Hall regime. The capacitive coupling of localized exce…
