Microscopic structure of the vortex cores in granular niobium: A coherent quantum puzzle
V. S. Stolyarov, V. Neverov, A. V. Krasavin +12
When macroscopic quantum condensates -- superconductors, superfluids, cold atoms and ions, polaritons etc. -- are put in rotation, a quantum vortex lattice forms inside. In homogen…
Surface reconstruction-driven band folding and spin-orbit enhancement at the -antimonene/Au(111) interface
Thomas Pierron, José de Jesùs Villalobos Castro, Etienne Barre +9
The electronic properties of the two-dimensional (2D) phase of antimonene are unique, featuring unpinned Dirac cones that can be moved with strain. Here we investigate the str…
Nernst effect and its thickness dependence in superconducting NbN films
Thomas Bouteiller, Arthur Marguerite, Ramzy Daou +6
Superconducting thin films and layered crystals display a Nernst signal generated by short-lived Cooper pairs above their critical temperature. Several experimental studies have br…
Selective band engineering of Bi/Si(111) by boron segregation
E. Barre, J. Villalobos-Castro, T. Pierron +4
Atomically thin layers of metals deposited on semiconductors display a variety of physical properties such as superconductivity, charge density waves, topological phases, strong sp…
Magnetic force microscopy versus scanning quantum-vortex microscopy: Probing pinning landscape in granular niobium films
A. Yu. Aladyshkin, R. A. Hovhannisyan, S. Yu. Grebenchuk +7
We provide an overview of the methodology and fundamental principles associated with newly developed experimental technique -- scanning quantum-vortex microscopy [Hovhannisyan et a…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
