Shekhar Das works in experimental condensed matter physics, studying unconventional superconductivity and exotic electronic states in materials like topological insulators, Dirac and Weyl semimetals, and related compounds. Much of the work uses point-contact spectroscopy and scanning tunneling microscopy to probe how superconductivity emerges or is modified at surfaces, interfaces, and under pressure. This research connects to broader efforts to understand materials relevant to future quantum technologies.
Publication output rose to a peak around 2019 and has since settled into a steady but modest pace of about one to three papers per year through the mid-2020s.
