Michele Filippone: Identical Suppression and Universality of the Hall Response in Interacting Quantum Lattices

January 22 @ 2:00 pm - 4:00 pm
Kuščerjev seminar, Fakulteta za matematiko in fiziko UL, Jadranska 19
Ljubljana, Slovenia

The Hall effect is known as the voltage drop V perpendicular to the current I and magnetic field B (B⊥ I) measurable in electric conductors. Its importance relies in the fact that, at weak field, the Hall constant R = V/(IB) ≈ -1/(nq)   and measures the charge q and density n of charge carriers. Nevertheless, its calculation remains an open problem in strongly correlated systems. We demonstrate the identical suppression of the Hall response in quasi two-dimensional ballistic lattices, which is robust  to large…
