Marginal Influence of Anomalous Josephson Current on Odd-Frequency Spin-Triplet Pairing in Ferromagnetic Josephson Diodes
Subhajit Pal, Colin Benjamin
We examine how an anomalous Josephson current influences odd-frequency superconducting correlations in two Josephson junction geometries. The first consists of two ferromagnetic la…

Subhajit Pal, Colin Benjamin
We predict surface-induced odd-frequency (odd-) spin-triplet superconducting pairing can be a veritable signature of Majorana bound states (MBS) in a Josephson nodal -wave su…
Identification of odd-frequency superconducting pairing in Josephson junctions
Subhajit Pal, Aabir Mukhopadhyay, Vivekananda Adak +1
Optimal choice of spin polarization enables electron injection into the helical edge state at a precise position, despite the uncertainty principle, permitting access to specific n…
Giant electromechanical response from defective non-ferroelectric epitaxial BaTiO3 integrated on Si 100
Sandeep Vura, Shubham Kumar Parate, Subhajit Pal +15
Lead free, silicon compatible materials showing large electromechanical responses comparable to, or better than conventional relaxor ferroelectrics, are desirable for various nanoe…
Yu-Shiba-Rusinov bound states boost odd-frequency superconductivity
Subhajit Pal, Colin Benjamin
We predict that the occurence of zero energy Yu-Shiba-Rusinov(YSR) bound states in two different setups, metal-spin flipper-metal-s-wave superconductor () and sup…
Honing in on a topological zero-bias conductance peak

Subhajit Pal, Colin Benjamin
A 1D Josephson junction loop, doped with a spin-flipper and attached to two thermal reservoirs, operates as a heat engine or a refrigerator, a Joule pump, or even a cold pump. When…
Bulk photovoltaic effect in BaTiO-based ferroelectric oxides: An experimental and theoretical study
Subhajit Pal, S. Muthukrishnan, Banasree Sadhukhan +3
The bulk photovoltaic effect exhibited by the non-centrosymmetric system gains research interest due to the observed large open-circuit voltage. The ferroelectric systems exhibitin…
Probing the topological character of superconductors via non-local Hanbury-Brown and Twiss correlations
Tusaradri Mohapatra, Subhajit Pal, Colin Benjamin
Superconductors can be classified as topological or not based on whether time-reversal symmetry (TRS), chiral symmetry, and particle-hole symmetry are preserved or not. Further, to…
Exciting odd frequency equal-spin-triplet correlations at metal-superconductor interfaces
Subhajit Pal, Colin Benjamin
We predict the occurrence of odd frequency equal-spin-triplet correlations at a normal metal-superconductor junction. This result is significant because equal-spin-triplet correlat…
Stability of Majorana bound states in the presence of spin-flip scattering
Subhajit Pal, Colin Benjamin
A popular evidence of the existence of Majorana bound states(MBS) is a quantized zero-bias conductance peak(ZBCP) which is robust to scattering by impurities, a consequence of its…

A ferromagnetic Josephson junction with a spin-flipper (magnetic impurity) sandwiched in-between acts as a phase battery that can store quantized amounts of superconducting phase d…

Subhajit Pal, Colin Benjamin
We examine a Josephson junction with two Ferromagnets and a spin flipper sandwiched between two superconductors. In such Ferromagnetic Josephson junctions, equilibrium spin torque…
