Supercurrent detection and manipulation of topological phase transitions in Shiba-Majorana hybrid systems
Debika Debnath, Ioannis Ioannidis, Paramita Dutta +2
The non-Abelian statistics of Majorana zero modes has inspired numerous proposals for their detection and manipulation in topological superconductors. Implementations based on magn…
Spin polarization and diode effect in thermoelectric current through altermagnet-based superconductor heterostructures
Debika Debnath, Arijit Saha, Paramita Dutta
The recent advent of a new class of magnetic material named as {\it altermagnet} (AM), characterized by a combination of momentum-dependent spin splitting with zero net magnetizati…
Superconducting order parameter in aperiodic binary systems
Sougata Biswas, Debika Debnath, Paramita Dutta
Recent discovery of the superconducting ground state in systems lacking perfect periodicity but with long-range ordering has opened up an exciting new avenue for superconductivity…
Field-free Josephson diode effect in interacting chiral quantum dot junctions
Debika Debnath, Paramita Dutta
We investigate chiral quantum dot (QD)-based Josephson junction and show the correlation-induced Josephson diode effect (JDE) in it. The presence of electron-electron interaction s…
Gate-tunable Josephson diode effect in Rashba spin-orbit coupled quantum dot junctions
Debika Debnath, Paramita Dutta
We theoretically explore Josephson diode effect (JDE) in superconductor/quantum dot (QD)/superconductor junction in the presence of a magnetic field and Rashba spin-orbit interacti…
