Dissipationless transport in low density bilayer systems
Ady Stern, S. Das Sarma, Matthew P. A. Fisher +1
In a bilayer electronic system the layer index may be viewed as the z-component of an isospin-1/2. An XY isospin-ordered ferromagnetic phase was observed in quantum Hall systems an…
Skyrmion Dynamics and NMR Line Shapes in QHE Ferromagnets
Jairo Sinova, S. M. Girvin, T. Jungwirth +1
The low energy charged excitations in quantum Hall ferromagnets are topological defects in the spin orientation known as skyrmions. Recent experimental studies on nuclear magnetic…
Short-Range Interactions and Scaling Near Integer Quantum Hall Transitions
Ziqiang Wang, Matthew P. A. Fisher, S. M. Girvin +1
We study the influence of short-range electron-electron interactions on scaling behavior near the integer quantum Hall plateau transitions. Short-range interactions are known to be…
Field-tilt Anisotropy Energy in Quantum Hall Stripe States
T. Jungwirth, A. H. MacDonald, L. Smrcka +1
Recently reported giant anisotropy in the longitudinal resistivity of a 2D electron system with valence Landau level index has been interpreted as a signal of unidirectio…
Monte Carlo study of a two-dimensional quantum ferromagnet
Patrik Henelius, Anders W. Sandvik, Carsten Timm +1
We present quantum Monte Carlo results for the field and temperature dependence of the magnetization and the spin-lattice relaxation rate of a two-dimensional quant…
