Skyrmions in Quantum Hall Systems with Realistic Force-Laws
N. R. Cooper
We study the charged excitations of quantum Hall systems at integer filling fractions , for a force-law that takes account of the finite width of the electron gas. For typi…
The effect of monomer evaporation on a simple model of submonolayer growth
Pablo Jensen, Hernán Larralde, Alberto Pimpinelli
We present a model for thin film growth by particle deposition that takes into account the possible evaporation of the particles deposited on the surface. Our model focuses on the…
Optical absorption of strongly correlated half-filled Mott-Hubbard chains
F. Gebhard, K. Bott, M. Scheidler +2
In this last of three articles on the optical absorption of electrons in a half-filled Peierls-distorted chain we address the dimerized extended Hubbard model in the limit of a lar…
Exact results for the optical absorption of strongly correlated electrons in a half-filled Peierls-distorted chain
F. Gebhard, K. Bott, M. Scheidler +2
In this second of three articles on the optical absorption of electrons in a half-filled Peierls-distorted chain we present exact results for strongly correlated tight-binding elec…
Optical absorption of non-interacting tight-binding electrons in a Peierls-distorted chain at half band-filling
F. Gebhard, K. Bott, M. Scheidler +2
In this first of three articles on the optical absorption of electrons in half-filled Peierls-distorted chains we present analytical results for non-interacting tight-binding elect…
Statistical properties of the low-temperature conductance peak-heights for Corbino discs in the quantum Hall regime
N. R. Cooper, B. I. Halperin, Chin-Kun Hu +1
A recent theory has provided a possible explanation for the ``non-universal scaling'' of the low-temperature conductance (and conductivity) peak-heights of two-dimensional electron…
