Chirality of Zitterbewegung and its relation to Berry curvature in Dirac systems
Sonja Predin
We establish an exact analytical relation between Zitterbewegung dynamics and the band geometry in two-dimensional Dirac systems. By identifying a time-independent antisymmetric ob…

Charge fluctuations, hydrodynamics and transport in the square-lattice Hubbard model
J. Vucicevic, S. Predin, M. Ferrero
Recent experimental results suggest that a particular hydrodynamic theory describes charge fluctuations at long wavelengths in the square-lattice Hubbard model. Due to the continui…

Dipole representation of composite fermions in graphene quantum Hall systems
Sonja Predin
The even denominator fractional quantum Hall effect has been experimentally observed in graphene in the fourth Landau level (). This paper is motivated by recent studies reg…
