Charge-density-wave states in double-layer graphene structures in a high magnetic field
Csaba Toke, Vladimir I. Fal'ko
We study the phases of correlated charge-density waves that form at a high magnetic field in two parallel graphene flakes separated by a thin insulator. The predicted phases includ…
Infrared absorption by graphene-hBN heterostructures
D. S. L. Abergel, J. R. Wallbank, Xi Chen +2
We propose a theory of optical absorption in monolayer graphene-hexagonal boron nitride (hBN) heterostructures. In highly oriented heterostructures, the hBN underlay produces a lon…
Moiré minibands in graphene heterostructures with almost commensurate sqrt3 x sqrt3 hexagonal crystals
J. R. Wallbank, M. Mucha-Kruczynski, V. I. Fal'ko
We present a phenomenological theory of the low energy moiré minibands of Dirac electrons in graphene placed on an almost commensurate hexagonal underlay with a unit cell pproximat…
Observation of even denominator fractional quantum Hall effect in suspended bilayer graphene
Dong-Keun Ki, Vladimir I. Fal'ko, Dmitry A. Abanin +1
We investigate low-temperature magneto-transport in recently developed, high-quality multi-terminal suspended bilayer graphene devices, enabling the independent measurement of the…
Monolayer MoS2: trigonal warping, "Γ-valley", and spin-orbit coupling effects
Andor Kormányos, Viktor Zólyomi, Neil D. Drummond +3
We use a combined ab-initio calculations and k.p theory based approach to derive a low-energy effective Hamiltonian for monolayer MoS2 at the K point of the Brillouin zone. It capt…
Transport signatures of pseudo-magnetic Landau levels in strained graphene ribbons
Diana A. Gradinar, Marcin Mucha-Kruczyński, Henning Schomerus +1
In inhomogeneously strained graphene, low-energy electrons experience a valley-antisymmetric pseudo-magnetic field which leads to the formation of localized states at the edge betw…
