Theory of the Half-Polarized Quantum Hall States
V. M. Apalkov, T. Chakraborty, P. Pietilainen +1
We report a theoretical analysis of the half-polarized quantum Hall states observed in a recent experiment. Our numerical results indicate that the ground state energy of the quant…
Comment on ``Composite Fermion Hofstadter Problem: Partially Polarized Density Wave States in the ...''
V. M. Apalkov, T. Chakraborty, P. Pietilainen +1
In a recent paper [Phys.Rev.Lett. 82, 3665 (1999)], magnetic field driven spin transitions in fractional quantum Hall (FQH) states were reported, and in particular, at filling fact…
Impurity Effects and Spin Polarizations in a Narrow Quantum Hall System
Tapash Chakraborty, K. Niemelä, P. Pietiläinen
The temperature dependence of electron spin polarization for a narrow quantum Hall system shows behavior analogous to that of a two-dimensional system at major filling factors. At…
Theory of Incompressible States in a Narrow Channel
Tapash Chakraborty, K. Niemelä, P. Pietiläinen
We report on the properties of a system of interacting electrons in a narrow channel in the quantum Hall effect regime. It is shown that an increase in the strength of the Coulomb…
