Relation between the areal rate of Zitterbewegung and Berry curvature in two-band systems
Sonja Predin
We introduce the Zitterbewegung areal rate operator to study the relation between the orientation of trembling motion and band topology. Constructed from the oscillatory interband…
Dipole representation of half-filled Landau level
S. Predin, A. Knežević, M. V. Milovanović
We introduce a variant of dipole representation for composite fermions in a half-filled Landau level, taking into account the symmetry under exchange of particles and holes. This i…
Entanglement spectra of superconductivity ground states on the honeycomb lattice
Sonja Predin, John Schliemann
We analytically evaluate the entanglement spectra of the superconductivity states in graphene, primarily focusing on the s-wave and chiral superconducti…
Trigonal Warping in Bilayer Graphene: Energy versus Entanglement Spectrum
Sonja Predin, Paul Wenk, John Schliemann
We 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 o…
On the coexistence of antiferromagnetism and d + i d superconducting correlations in the graphene bilayer
M. V. Milovanović, S. Predin
We discuss t-J-U model on a honeycomb monolayer that has the same low-energy description of the kinetic term as graphene bilayer, and in particular study coexistence of antiferroma…
