Maiti Research Group
Dr. Maiti is currently looking for Ph.D. students. If you are interested in working in this field you are encouraged to contact him directly at saurabh.maiti@concordia.ca.
The Maiti Research Group focuses on the collective phenomena and quantum phases in low-dimensional systems. More specifically, the research interests include:
- Collective phenomena
- Spin-orbit coupled systems
- Unconventional superconductors
- Correlated electronic systems
- Gauge fields in lattice systems
We are interested in studying low-dimensional systems like the lattice of Graphene, Kagome, etc. (which are strictly 2D); and Fe and Cu based superconductors (which are quasi-2D). These systems can host a range of quantum phases like spin-liquid, unconventional superconductivity, magnetism, density waves, or any combination of them. We are also interested in understanding the role of various gauge fields in systems with a degenerate energy excitation spectrum.
Accounting for electronic correlations, we also look for unique signatures of the collective phenomena in such quantum phases. Some examples of such signatures are chiral-spin waves in spin-orbit coupled systems that can have potential application in Spintronics/Magnonics; and collective modes in superconductors that can provide insight into the pairing mechanism of high-Tc superconductors. We also work on computing experimentally observable quantities (like Raman, optical absorption spectrum) that can help detect these signatures and track the boundaries between various phases.
