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…
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…
Floquet-engineered diode performance in a Majorana-quantum dot Josephson junction
Koustav Roy, Gourab Paul, Debika Debnath +2
We study nonreciprocal signatures of Josephson current (JC) in a quantum dot (QD)-based Josephson junction (JJ) that comprises of two periodically driven Kitaev chains (KCs) couple…
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…
