High-field Josephson effect enabled by a moiré Hofstadter spectrum
A. DÃez-Carlón, M. Cárdenes Wuttig, N. Wei +7
The paper demonstrates that graphene/hBN Josephson junctions engineered with a moiré superlattice can maintain phase‑coherent superconducting transport at magnetic fields up to 6 T…
Revealing electron-electron interactions in graphene at room temperature with the quantum twisting microscope
M. Lee, I. Das, J. Herzog-Arbeitman +20
The Quantum Twisting Microscope (QTM) is a groundbreaking instrument that enables energy- and momentum-resolved measurements of quantum phases via tunneling spectroscopy across twi…
Superconducting junctions with flat bands
P. Virtanen, R. P. S. Penttilä, P. Törmä +3
We analyze the properties of flat-band superconductor junctions that behave differently from ordinary junctions containing only metals with Fermi surfaces. In particular, we show h…
Probing the flat-band limit of the superconducting proximity effect in Twisted Bilayer Graphene Josephson junctions
A. Diez-Carlon, J. Diez-Merida, P. Rout +13
While extensively studied in normal metals, semimetals and semiconductors, the superconducting (SC) proximity effect remains elusive in the emerging field of flat-band systems. In…
