Phase diagram of the quantum Hall state in bilayer graphene
Udit Khanna, Ke Huang, Ganpathy Murthy +5
Bilayer graphene exhibits a rich phase diagram in the quantum Hall regime, arising from a multitude of internal degrees of freedom, including spin, valley, and orbital indices. The…
Perpendicular electric field drives Chern transitions and layer polarization changes in Hofstadter bands
Pratap Chandra Adak, Subhajit Sinha, Debasmita Giri +10
Moiré superlattices engineer band properties and enable observation of fractal energy spectra of Hofstadter butterfly. Recently, correlated-electron physics hosted by flat bands in…
Broken symmetry and competing orders in Weyl semimetal interfaces
Ritajit Kundu, H. A. Fertig, Arijit Kundu
We consider interaction-induced broken symmetry states of two Weyl semimetal surfaces with multiple Fermi-arc (FA) states. In the presence of inter- and intra-surface Coulomb inter…
Plasmonic Transverse Dipole Moment in Chiral Fermion Nanowires
Jinlyu Cao, Herb Fertig, Luis Brey
Plasmons are elementary quantum excitations of conducting materials with Fermi surfaces. In two dimensions they may carry a static dipole moment that is transverse to their momentu…
Renormalized Magic Angles in Asymmetric Twisted Graphene Multilayers
Adam Eaton, Yantao Li, Herbert Fertig +1
Stacked graphene multilayers with a small relative twist angle between each of the layers have been found to host flat bands at a series of magic angles. We consider the effect tha…
Weyl Semimetal Path to Valley Filtering in Graphene
Ahmed Khalifa, Ribhu K. Kaul, Efrat Shimshoni +2
We propose a device in which a sheet of graphene is coupled to a Weyl semimetal, allowing for the physical access to the study of tunneling from two-dimensional to three dimensiona…
