Nanoparticle manipulation with a carbon fiber tip in an electron microscope for -SQUID magnetometry

Umesh Chandra Thuwal, Sumanta Maity, Clemens B. Winkelmann +2

We report a carbon-fiber-tip based nanomanipulation system integrated into a scanning electron microscope for individual nanoparticle (NP) manipulation on a surface. Electrochemica…

Evidence for chiral supercurrent in quantum Hall Josephson junctions

Hadrien Vignaud, David Perconte, Wenmin Yang +9

Hybridizing superconductivity with the quantum Hall (QH) effects has major potential for designing novel circuits capable of inducing and manipulating non-Abelian states for topolo…

Absence of edge reconstruction for quantum Hall edge channels in graphene devices

Alexis Coissard, Adolfo G. Grushin, Cécile Repellin +7

Electronic edge states in topological insulators have become a major paradigm in physics. The oldest and primary example is that of quantum Hall (QH) edge channels that propagate a…

Calorimetry of a Quantum Phase Slip

E. Gümüş, D. Majidi, D. Nikolić +8

In a Josephson junction, which is the central element in superconducting quantum technology, irreversibility arises from abrupt slips of the gauge-invariant quantum phase differenc…

Magnetization Reversal Across Multiple Serial Barriers in a Single FeO Nanoparticle

Sagar Paul, Ganesh Kotagiri, Rini Ganguly +4

Depinning of nanoscale magnetic textures, such as domain walls, vortices and skyrmions, is of paramount importance for magnetic storage and information processing. We measure time-…

Imaging tunable quantum Hall broken-symmetry orders in graphene

Alexis Coissard, David Wander, Hadrien Vignaud +9

When electrons populate a flat band their kinetic energy becomes negligible, forcing them to organize in exotic many-body states to minimize their Coulomb energy. The zeroth Landau…
