Lifshitz transitions and isospin polarization in twist-decoupled monolayer-bilayer graphene
Alex Boschi, Leonardo Sabattini, Sergey Slizovskiy +11
Bernal-stacked bilayer graphene (BLG) hosts correlated electronic phases tied to low-energy Lifshitz transitions at saddle points in its valence band. To access this regime, ultral…
Scanning Gate Microscopy Modulation of Supercurrent in Graphene Josephson Junctions
Ivan Villani, Samuele Fracassi, Niccolò Traverso Ziani +9
The paper uses scanning gate microscopy to locally modulate and map the supercurrent in hBN‑encapsulated graphene Josephson junctions with niobium contacts, analyzing how tip volta…
Graphene Josephson diodes from inherent asymmetric disorder
Ivan Villani, Luca Chirolli, Matteo Carrega +10
Josephson diodes are non-reciprocal superconducting devices characterized by different switching currents depending on the current flow direction. They recently attracted considera…
SpectraFormer: an Attention-Based Raman Unmixing Tool for Accessing the Graphene Buffer-Layer Signature on SiC
Dmitriy Poteryayev, Pietro Novelli, Annalisa Coriolano +7
Raman spectroscopy is a key tool for graphene characterization, yet its application to graphene grown on silicon carbide (SiC) is strongly limited by the intense and variable secon…
Phason-driven temperature-dependent transport in moiré graphene
Alex Boschi, Alejandro Ramos-Alonso, Vaidotas Mišeikis +9
The electronic and vibrational properties of 2D materials are dramatically altered by the formation of a moiré superlattice. The lowest-energy phonon modes of the superlattice are…
Quasi--periodic supercurrent at quantum Hall transitions
Ivan Villani, Matteo Carrega, Alessandro Crippa +9
The combination of superconductivity and quantum Hall (QH) effect is regarded as a key milestone in advancing topological quantum computation in solid-state systems. Recent quantum…
