Welcome to the Laboratory for Quantum Materials
About our group
We are exploring and designing materials at the atomic scale to both realize and engineer novel quantum phenomena in solid state systems. We are studying electronic and magnetic properties of these materials with an emphasis on the interplay between symmetry, strong correlations, topology, and superconductivity. Our work is inter-disciplinary, where we frequently employ concepts and tools from the fields of physics, materials science, electrical engineering, and chemistry. We are interested in potential device applications of quantum materials in the areas of spintronics, thermoelectrics, plasmonics, and quantum computing.
Our tools
Recent Updates
We work with cutting edge synthesis tools such as molecular-beam epitaxy (MBE) and sputtering, which allow us to create materials with atomic precision in a bottoms-up manner that often cannot be achieved in bulk single crystals.
​
We routinely engage with a variety of spectroscopy techniques such as photoemission, x-ray scattering, scanning tunnelling spectroscopy, and optical methods, either directly or through collaborations to understand the underlying microscopic mechanisms at play, which in turn helps us design materials with tailored properties.
​
We make use of large scale synchrotron facilities around the world to perform angle-resolved photoemission spectroscopy (ARPES), resonant x-ray scattering (RXS), and x-ray magnetic circular dichrosim (XMCD) measurements.
​
Our work involves fabrication of mesoscopic and nanoscale devices and performing low-temperature transport and magnetic measurements.
July 28, 2022: Our overview article on Full and Half-Heusler compounds for the special issue of MRS Bulletin on the same topic is now published. Full and Half-Heusler Compounds

Jan, 2022: Debashis joins us as an NPDF fellow funded by DST-SERB. Welcome Debashis!
​
Dec 27, 2021: More cheers as 2021 draws to a close! Our paper on tuning magnetotransport properties in topological Heusler semimetal Pt1-xAuxLuSb is now out. We show how substitution alloying can be an effective strategy to reveal signatures of topological properties of semimetallic systems in bulk measurements. Physical Review Materials, 5, 124207 (2021)
