Loop currents and anomalous Hall effect from time-reversal symmetry-breaking superconductivity on the honeycomb lattice
P. M. R. Brydon, D. S. L. Abergel, D. F. Agterberg +1
We study a tight-binding model on the honeycomb lattice of chiral -wave superconductivity that breaks time-reversal symmetry. Due to its nontrivial sublattice structure, we show…
Weakly damped acoustic plasmon mode in transition metal dichalcogenides with Zeeman splitting
K. Kechedzhi, D. S. L. Abergel
We analyze the effect of a strong Zeeman field on the spectrum of collective excitations of monolayer transition metal dichalcogenides. The combination of the Dresselhaus type spin…
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…
Interlayer excitonic superfluidity in graphene
D. S. L. Abergel, M. Rodriguez-Vega, Enrico Rossi +1
We discuss the conditions under which the predicted (but not yet observed) zero-field interlayer excitonic condensation in double layer graphene has a critical temperature high eno…
2D compressibility of surface states on 3D topological insulators
D. S. L. Abergel, S. Das Sarma
We develop a theory for the compressibility of the surface states of 3D topological insulators and propose that surface probes of the compressibility via scanning single electron t…
Density fluctuation effects on the exciton condensate in double layer graphene
D. S. L. Abergel, Rajdeep Sensarma, S. Das Sarma
We describe the robustness of an excitonic condensate in double layer graphene against layer density fluctuations and the associated charge inhomogeneity, and discuss the implicati…
