Double-peak Majorana bound states in altermagnet--superconductor heterostructures
Pankaj Sharma, Narayan Mohanta
We study Majorana bound states in a planar Josephson junction in which the middle channel is a -wave altermagnetic metal deposited on a proximitized two-dimensional electron gas…
Diode effect in a skyrmion-coupled high-temperature Josephson junction
Digvijay Singh, Pankaj Sharma, Narayan Mohanta
We show that a planar Josephson junction having -wave superconducting regions, with a skyrmion crystal placed underneath, produces a robust gate-tunable superconducting diode ef…
Multiple Majorana bound states and their resilience against disorder in planar Josephson junctions
Pankaj Sharma, Narayan Mohanta
Planar Josephson junctions are theoretically predicted to harbor zero-energy Majorana bound states (MBS) in a tunable two-dimensional geometry, at the two ends of the middle metall…
Magnetic field-free braiding and nontrivial fusion of Majorana bound states in high-temperature planar Josephson junctions
Pankaj Sharma, Narayan Mohanta
Demonstration of non-Abelian statistics of Majorana bound states (MBS) is crucial for the realization of fault-tolerant topological quantum computation. Two-dimensional platforms s…
