Hofstadter's butterfly in moire superlattices: A fractal quantum Hall effect
C. R. Dean, L. Wang, P. Maher +12
Electrons moving through a spatially periodic lattice potential develop a quantized energy spectrum consisting of discrete Bloch bands. In two dimensions, electrons moving through…
Evidence for a Spin Phase Transition at ν=0 in Bilayer Graphene
Patrick Maher, Cory R. Dean, Andrea F. Young +5
The most celebrated property of the quantum spin Hall effect is the presence of spin-polarized counter-propagating edge states. This novel edge state configuration has also been pr…
Spin and valley quantum Hall ferromagnetism in graphene
Andrea F. Young, Cory R. Dean, Lei Wang +7
In a graphene Landau level (LL), strong Coulomb interactions and the fourfold spin/valley degeneracy lead to an approximate SU(4) isospin symmetry. At partial filling, exchange int…
