Long-range Phase Coherence and Tunable Second Order -Josephson Effect in a Dirac Semimetal
Pranava K. Sivakumar, Mostafa T. Ahari, Jae-Keun Kim +6
Superconducting diode effects have recently attracted much attention for their potential applications in superconducting logic circuits. Several mechanisms such as magneto-chiral e…
Intrinsic supercurrent non-reciprocity coupled to the crystal structure of a van der Waals Josephson barrier
Jae-Keun Kim, Kun-Rok Jeon, Pranava K. Sivakumar +4
Non-reciprocal electronic transport in a spatially homogeneous system arises from the simultaneous breaking of inversion and time-reversal symmetries. Superconducting and Josephson…
Josephson diode effect from Cooper pair momentum in a topological semimetal
Banabir Pal1, Anirban Chakraborty, Pranava K. Sivakumar +11
In the presence of an external magnetic field Cooper pairs in noncentrosymmetric superconductors can acquire finite momentum. Recent theory predicts that such finite-momentum pairi…
Realization of the field-free Josephson Diode
Heng Wu, Yaojia Wang, Yuanfeng Xu +7
The superconducting analog to the semiconducting diode, the Josephson diode, has long been sought, with multiple avenues to realization proposed by theorists. Exhibiting magnetic-f…
Anisotropic proximity-induced superconductivity and edge supercurrent in Kagome metal, K1-xV3Sb5
Yaojia Wang, Shuoying Yang, Pranava K. Sivakumar +11
Materials with transition metals in triangular lattices are of great interest for their potential combination of strong correlation, exotic magnetism and electronic topology. Kagom…
