We propose a simple model quantum network consisting of diamond-shaped plaquettes with deterministic distribution of magnetic and non-magnetic atoms in presence of a uniform external magnetic flux in each plaquette and predict that such a simple model can be a prospective candidate for spin filter as well as flux driven spintronic switch. The orientations(More)
We study transport and zero frequency shot noise properties of a normal metal-superconductor-normal metal (NSN) junction, with the superconductor having mixed singlet and chiral triplet pairings. We show that in the subgapped regime when the chiral triplet pairing amplitude dominates over that of the singlet, a resonance phenomena emerges out at zero energy(More)
The paper summarises the work carried out at the Indian Institute of Science in recent time on Laser processing of dissimilar materials in welding and surface alloying configurations for various model metallurgical systems. The microstructural features observed in the systems studied are summarized. A three dimensional transient computational model, to(More)
