Half-filled 2D bilayers in a strong magnetic field: Revisiting the fractional quantum Hall effect
S. Das Sarma, Michael R. Peterson
We examine the quantum phase diagram of the fractional quantum Hall effect in the lowest Landau level in half-filled bilayer structures as a function of tunneling strength and laye…
Interaction-tuned compressible-to-incompressible phase transitions in the quantum Hall systems
Z. Papić, N. Regnault, S. Das Sarma
We analyze transitions between quantum Hall ground states at prominent filling factors in the spherical geometry by tuning the width parameter of the Zhang-Das Sarma interactio…
Localization in one-dimensional incommensurate lattices beyond the Aubry-André model
J. Biddle, B. Wang, D. J. Priour +1
Localization properties of particles in one-dimensional incommensurate lattices without interaction are investigated with models beyond the tight-binding Aubry-André (AA) model. Ba…
The enigma of the nu=0 quantum Hall effect in graphene
S. Das Sarma, Kun Yang
We apply Laughlin's gauge argument to analyze the quantum Hall effect observed in graphene when the Fermi energy lies near the Dirac point, and conclude that this necessarily…
Splitting of Majorana modes due to intervortex tunneling in a p + ip superconductor
Meng Cheng, Roman M. Lutchyn, Victor Galitski +1
We consider a two-dimensional px+i py superconductor in the presence of multiple vortices, which support zero-energy Majorana fermion states in their cores. Intervortex tunnelings…
Pure quantum dephasing of a solid state electron spin qubit in a large nuclear spin bath coupled by long-range hyperfine-mediated interactions
L. Cywinski, W. M. Witzel, S. Das Sarma
We investigate decoherence due to pure dephasing of a localized spin qubit interacting with a nuclear spin bath. Although in the limit of a very large magnetic field the only decoh…
