graphenemonolayersWe present a mainly analytical study of the entanglement spectrum of Bernal-stacked graphene bilayers in the presence of trigonal warping in the energy spectrum. Upon tracing out one layer, the entanglement spectrum shows qualitative geometric differences to the energy spectrum of a ...

High-Energy Limit of Massless Dirac Fermions in Multilayer Graphene using Magneto-Optical Transmission Spectroscopy This result is in good agreement with the theoretical model, which includes trigonal warping of the Fermi surface and higher-order band corrections. ......
Trigonal warping, satellite Dirac points, and multiple field tuned topological transitions in twisted double bilayer grapheneWe show that the valley Chern number of the low-energy band in twisted double bilayer graphene can be tuned through two successive topological transitions, where the direct band ...

We study the low energy properties of warped monolayer graphene, where the symmetry of the original honeycomb lattice reveals itself. The zero energy solutions are Majorana fermions, whose wave function, originating from the corresponding modified Dirac equation is spatially localized. Experimental ...

At low energies, in the vicinity of the Dirac points, band energy of the monolayer graphene is isotropic at the Fermi level. Meanwhile, at the intermediate Fermi energies anisotropic effects such as trigonal warping is expected to be the origin of the anisotropic resistivity. However, besides ...
Trigonal WarpingIn single layer graphene, the recently predicted anomalous Rabi frequency varies linearly with the intensity of applied pump field whereas in bilayer graphene it is proportional to the square of the intensity. In bilayer graphene, when the trigonal warping effect is taken in to ...
