Description:
Author(s): G. Zechner, W. Lang, M. Dosmailov, M. A. Bodea, and J. D. Pedarnig In superconductors with a periodic pinning potential, the vortices can lock into a commensurate arrangement, where each pin is filled by one vortex. Then, an intriguing duality between conduction electrons in a normal metal and mobile vortices in a superconductor arises. While the mutual repulsion of electrons can evoke a Mott insulator, the interaction between mobile and commensurably trapped vortices can lead to a vortex Mott metal-to-insulator transition with vanishing resistance. The authors report on a hitherto unknown manifestation of such a state, uncovered by measurements of the voltage orthogonal to the injected current. This vortex Hall effect exhibits a sharp peak and a change of sign when the number of vortices exactly matches that of the pins. [Phys. Rev. B 98, 104508] Published Tue Sep 18, 2018
