Signatures of a ferro-Josephson effect in twisted graphene
Ruiheng Su, Zhenxiang Gao, Christopher Coleman +9
When a spin-polarized current is driven across a magnetic domain wall, the resulting spin-transfer torque may, beyond a critical threshold, set the wall's moments into precession.…
Orbital Competition in Bilayer Graphene's Fractional Quantum Hall Effect
Bishoy M. Kousa, Nemin Wei, Allan H. MacDonald
The lowest Landau level of bilayer graphene has an octet of internal degrees of freedom, composed from spin, valley and orbital two-level systems. Dominance of orbitals over…
Orbital and interlayer Skyrmions crystals in bilayer graphene
R. Cote, Wenchen Luo, Branko Petrov +2
A graphene bilayer in a transverse magnetic field has a set of Landau levels with energies where is the effective cyclotron…
Anomalous Exciton-Condensation in Graphene Bilayers
Yafis Barlas, Rene Côté, J. Lambert +1
In ordinary semiconductor bilayers, exciton condensates appear at total Landau level filling factor . We predict that similar states will occur in Bernal stacked graphene…
Internal Excitations and Dissipative Damping of Quantum Hall Skyrmions
H. A. Fertig, L. Brey, R. Cote +1
We propose an intrinsic maximum speed for dissipationless E cross B drift of Skyrmion quasiparticles in quantum Hall ferromagnets. When this speed is exceeded, Skyrmions can radiat…
Skyrme Crystal In A Two-Dimensional Electron Gas
L. Brey, H. A. Fertig, R. Cote +1
The ground state of a two-dimensional electron gas at Landau level filling factors near is a Skyrme crystal with long range order in the positions and orientations of the top…
Collective Modes of Soliton-Lattice States in Double-Quantum-Well Systems
R. Cote, L. Brey, H. Fertig +1
In strong perpendicular magnetic fields double-quantum-well systems can sometimes occur in unusual broken symmetry states which have interwell phase coherence in the absence of int…
