Our primary research focuses on investigating quantum phenomena in layered low-dimensional quantum materials. Recently we have started working on vdW materials, for example, (1) Quasi-2D vdW ferromagnets and topological materials, and (2) Quasi-1D vdW materials. These materials provide us with a versatile scientific platform for studying critical quantum phenomena, such as the dynamical response of charge density waves (CDW) and topological phases in 1D chains, with enormous potential for device applications.

June 2022: Congratulations to Sk Kalimuddin and Dr. Biswajit Das for the manuscript titled "Nonlinear coherent light-matter interaction in 2D MoSe2 nanoflakes for all-optical switching and logic applications", accepted in Advanced Optical Materials.

May 2022: Congratulations to Suman Kalyan Pradhan for the manuscript titled "Emergence of exchange bias effect in double perovskite La2Cu0.9Fe0.1IrO6 originated from Fe doping", published in the Journal of Magnetism and Magnetic Materials.

Our primary research focus is the investigation of quantum phenomena in various functional quantum materials, including superconductors, novel magnetic (such as 2D magnets and spin liquid systems), and topological materials. We also study their properties in nanostructures to probe critical quantum phenomena in the nanoscale for device applications.

We probe these materials by measuring the electrodynamic response at different energy scales using measurement techniques such as THz spectroscopy and low-frequency 1/f conductance noise spectroscopy.  Here is the list of a few important measurement probes used for our study.

1) THz spectroscopy

Currently, we are setting up the THz spectroscopy using components purchased from different sources.

2) Electron transport

a) Low-frequency 1/f conductance noise spectroscopy – DC and lock-in based 1/f  noise measurements.

b) Point contact spectroscopy

(c) Four probe transport/ hall effect down to 1.7 K

3) Thermal transport

“Thermoelectric power,” “thermal conductivity,” and “differential scanning calorimetry (DSC)” to study phase transition and slow dynamics of different materials down to 77 K.

4) Spacial self-phase modulation (SSPM) spectroscopy

The strong light-matter interactions in 2D and 1D materials can produce many interesting nonlinear optical phenomena and quasiparticle excitations that can have far-reaching implications in science and technology. The recently developed SSPM spectroscopy will be very effective in understanding the response of charge density wave (CDW) and their coherent interactions with light in 1D and 2D materials. Recently, we used SSPM to study nonlinear light-matter interactions in MoSe2 based composites and FnGeTe2 (with n = 3, 4 and 5).
