Nanosculpting lateral weak link junctions in superconducting Fe(Te,Se)/Bi2Te3 with focused Si++ ions and implications on vortex pinning
Debarghya Mallick, Sujoy Ghosh, An Hsi Chen +10
Superconductor-normal-superconductor (SC-N-SC) weak links enable Cooper-pair tunneling and serve as Josephson junctions (JJs) used in modern superconducting qubits. Conventional JJ…

Evidence of chiral fermion edge modes through geometric engineering of thermal Hall in -RuCl
Heda Zhang, Gabor B. Halasz, Sujoy Ghosh +5
The experimental observation of half-integer-quantized thermal Hall conductivity in the Kitaev candidate material -RuCl has served as smoking-gun signature of non-Abelian a…
