Phase-dependent dissipation and supercurrent of a graphene-superconductor ring under microwave irradiation
Ziwei Dou, Taro Wakamura, Pauli Virtanen +8
A junction with two superconductors coupled by a normal metal hosts Andreev bound states whose energy spectrum is phase-dependent and exhibits a minigap, resulting in a periodic su…

Long- to short-junction crossover and field-reentrant critical current in Al/Ag-nanowires/Al Josephson junctions
A. Murani, S. Sengupta, A. Kasumov +5
We have probed the superconducting proximity effect through long high-quality monocrystalline Ag nanowires, by realizing Josephson junctions of different lengths, with different su…

Magnetic field anti-symmetry of photovoltaic voltage in evanescent microwave fields
A. Chepelianskii, S. Guéron, F. Pierre +3
A two dimensional electron system without spatial inversion symmetry develops a sample specific dc voltage when exposed to a microwave radiation at low temperature. We investigate…
