Electronic correlations give rise to fascinating macroscopic phenomena such as
superconductivity, magnetism, and topological phases of matter. Although these …

In this review I discuss the application of scanning magnetic imaging to fundamental studies
of superconductors, concentrating on three scanning magnetic microscopies—scanning …

LaAlO3 and SrTiO3 are insulating, non-magnetic oxides, yet the interface between them
exhibits a two-dimensional electron system with high electron mobility, superconductivity at …

We show that the topologically protected flat band emerging on a surface of a nodal
fermionic system promotes the surface superconductivity due to an infinitely large density of …

Microscopic studies of superconductors and their vortices play a pivotal role in
understanding the mechanisms underlying superconductivity,,,,. Local measurements of …

Superconductivity in the iron pnictides is often closely connected to a nematic state in which
the tetragonal symmetry of the crystal is spontaneously broken. Determining the dominant …

▪ Abstract The scanning SQUID microscope (SSM) is a powerful tool for imaging magnetic
fields above sample surfaces. It has the advantage of high sensitivity and bandwidth and the …

Low-temperature scanning tunneling microscopy and spectroscopy are employed to
investigate twin boundaries in stoichiometric FeSe films grown by molecular beam epitaxy …

Surface superconductivity in rhombohedral graphite is a robust phenomenon which can
exist even when higher order hoppings between the layers lift the topological protection of …

Electronic, magnetic, and structural phase inhomogeneities are ubiquitous in strongly
correlated quantum materials. The characteristic length scales of the phase inhomogeneities …
