TL;DR: In this paper, the authors used scanning nanoSQUID (nano-superconducting quantum interference device) magnetic imaging to provide a direct visualization of the dynamics of the quantum phase transition between the two anomalous Hall plateaus in a Cr-doped (Bi,Sb)2Te3 thin film.

TL;DR: A scanning nanoscale thermometer reveals the mechanism for energy dissipation in ultrapure samples of graphene and visualizes and controlled phonon emission from individual atomic-scale defects in graphene.

TL;DR: In this paper , a SQUID-on-tip was used to directly image the nanoscale Berry-curvature-induced equilibrium orbital magnetism, the polarity of which is governed by the local Chern number, and detect its two constituent components associated with the drift and the self-rotation of the electronic wave packets.

TL;DR: A new nanoscale superconducting quantum interference device (SQUID) whose interference pattern can be shifted electrically in situ, eliminating the magnetic field "blind spots", and demonstrating spin sensitivity of 5 to 8 μB/Hz1/2 over a continuous field range of 0 to 0.5 T with promising applications for nanoscales scanning magnetic imaging.

TL;DR: In this article, a direct procedure for inversion of the magnetic field that avoids use of the stream function was proposed, which provides enhanced accuracy of current reconstruction over a wide range of noise levels.
