Towards numerically exact computation of conductivity in the thermodynamic limit of interacting lattice models
Jeremija KovaÄeviÄ, Michel Ferrero, JakÅ¡a VuÄiÄeviÄ
Computing dynamical response functions in interacting lattice models is a long standing challenge in condensed matter physics. In view of recent results, the dc resistivity $Ï_\ma…

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…
