Spin model for the Honeycomb
Paula Mellado
In the Van der Waal material , Ni atoms have spin S=1 and realize a honeycomb lattice. Six sulfur atoms surround each Ni and split their d manifold into three filled an…
Charge Smoothening and Band Flattening due to Hartree corrections in Twisted Bilayer Graphene
Louk Rademaker, Dmitry A. Abanin, Paula Mellado
Doping twisted bilayer graphene away from charge neutrality leads to an enormous buildup of charge inhomogeneities within each Moiré unit cell. Here we show, using unbiased real-sp…
Photoinduced Floquet topological magnons in Kitaev magnets
S. A. Owerre, Paula Mellado, G. Baskaran
We study periodically driven pure Kitaev model and ferromagnetic phase of the Kitaev-Heisenberg model on the honeycomb lattice by off-resonant linearly and circularly-polarized lig…
Charge-transfer insulation in twisted bilayer graphene
Louk Rademaker, Paula Mellado
We studied the real space structure of states in twisted bilayer graphene at the `magic angle' . The flat bands close to charge neutrality are composed of a mix of `…
Projective symmetry of partons in Kitaev's honeycomb model
Paula Mellado, Olga Petrova, Oleg Tchernyshyov
Low-energy states of quantum spin liquids are thought to involve partons living in a gauge-field background. We study the spectrum of Majorana fermions of Kitaev's honeycomb model…
Unpaired Majorana modes on dislocations and string defects in Kitaev's honeycomb model
Olga Petrova, Paula Mellado, Oleg Tchernyshyov
We study the gapped phase of Kitaev's honeycomb model (a spin liquid) on a lattice with topological defects. We find that some dislocations and string defects carry unpaired…
