Query: Stick-slip Phenomena and Memory Effects in Moving Vortex Matter   Manipulating vortices in non-conventional superconductors is nowadays a
challenging path toward controlling functionalities for superconducting
nanodevices. Here, we directly observe and control single vortex core
trajectories with unmatched resolution using a new scanning tunneling
spectroscopy at very low temperature. Our data show the depinning threshold of
a Bragg-glass in a weakly disordered superconductor, a clean 2H-NbSe2 crystal.
We first experimentally capture the linear and collective response, the
Campbell regime. Upon strong drives, the oscillating trajectories perform a
series of stick-slip motions that mimics the lattice periodicity. We then
theoretically elucidate this peculiar non-linear regime by solving the Langevin
dynamics equations. We additionally explore the impact of initial conditions
and reveal an enhancement of the long-range correlations with the cooling
procedure. Finally, our work establishes a connection between theory of vortex
pinning, memory effects and vortex lineshapes, thus offering a new platform to
investigate the relationship between viscous media and individual controllable
objects in any many-body systems.
