Phase-controlled perfect nonlocal spin and charge diode effects in a four-terminal Josephson junction with -wave magnets
Lovy Sharma, Bimal Ghimire, Manisha Thakurathi
We theoretically investigate charge and spin transport in a four-terminal Josephson junction with a normal-metal barrier. The top and bottom superconducting leads are equal-spin tr…

-wave magnet driven field-free Josephson diode effect
Lovy Sharma, Bimal Ghimire, Manisha Thakurathi
Recently, the superconducting diode effect (SDE), characterized by unequal critical currents in opposite directions, has been observed experimentally and predicted theoretically in…

Tunable Josephson diode effect in singlet superconductor-altermagnet-triplet superconductor junctions
Lovy Sharma, Manisha Thakurathi
Recently discovered phase of collinear magnet called, altermagnet breaks time reversal symmetry (TRS), exhibits momentum-dependent spin-splitting of band structure with zero net ma…
