Electronic structure of graphene-nanoribbons on hexagonal boron nitride
Yohanes S. Gani, D. S. L. Abergel, Enrico Rossi
Hexagonal boron nitride is an ideal dielectric to form two-dimensional heterostructures due to the fact that it can be exfoliated to be just few atoms thick and its a very low dens…
Interacting Dirac Materials
S. Banerjee, D. S. L. Abergel, H. Ågren +2
We investigate the extent to which the class of Dirac materials in two-dimensions provides general statements about the behavior of both fermionic and bosonic Dirac quasiparticles…
Robustness of topologically protected transport in graphene-boron nitride lateral heterostructures
D. S. L. Abergel
Previously, graphene nanoribbons set in lateral heterostructures with hexagonal boron nitride were predicted to support topologically protected states at low energy. We investigate…
True exciton condensate of one-dimensional electrons through interwire tunneling
A. Kantian, D. S. L. Abergel
We theoretically predict that a true bilayer exciton condensate,characterised by off-diagonal long range order and global phase coherence, can be created in one-dimensional solid s…
First-order quantum phase transition in three-dimensional topological band insulators
Vladimir Juricic, D. S. L. Abergel, A. V. Balatsky
Topological states of matter are characterized by global topological invariants which change their value across a topological quantum phase transition. It is commonly assumed that…
Infrared absorption of closely-aligned heterostructures of monolayer and bilayer graphene with hexagonal boron nitride
D. S. L. Abergel, M. Mucha-Kruczynski
We model optical absorption of monolayer and bilayer graphene on hexagonal boron nitride for the case of closely-aligned crystal lattices. We show that perturbations with different…
