Investigation of current-phase relation in topological insulator Josephson junction
In this thesis, we present current-phase relation (CPR) study of S-TI-S lateral Josephson junction (TIJJ). In a magnetic field, localized Majorana bound states (MBS) are predicted to exist at the core of Josephson vortices. One of the key characteristics of such MBS in TIJJ system is that they …

The current-phase relation of graphene-based Josephson junctions
The current-phase relation (CPR) of a Josephson junction reveals valuable information about the microscopic processes and symmetries that influence the supercurrent. For the work described in this thesis, we have studied the CPR of graphene-based Jospehson junctions, inspired by previous …

Exploring exotic superconducting order in La-based cuprate materials using Josephson interferometry
… through a junction depends on the difference in phase of the superconducting order parameter across the junction. We present the results of two measurements which involve the fabrication of Josephson junctions on unconventional high-temperature superconductors to study the physical processes …

Non-Sinusoidal Current -Phase Relations in Superconductor-Ferromagnet-Superconductor Josephson Junctions
We have directly measured the current-phase relation (CPR) of a superconductor-ferromagnet-superconductor (SFS) Josephson junction, and determined that it contains a positive second-harmonic term proportional to sin(2&phis;). The second-harmonic term becomes dominant near Tpi, the temperature at …

Phase-sensitive probes of extended topological Josephson junctions
… exhibit 4π-periodic signatures in the Josephson phase due to MBSs. We study multiple approaches to measuring phase-sensitive phenomena in S-TI-S Josephson junctions through indirect and direct measurements of the current-phase relation (CPR) using Josephson interferometry. Through indirect …
