Dibyendu's research broadly focuses on understanding non-equilibrium quantum dynamics in various physical systems. His current research interests are:
(a) Waveguide quantum electrodynamics (WQED) : see, e.g., Strongly interacting photons in one-dimensional continuum, D. Roy, C. M. Wilson, and O. Firstenberg, Rev. Mod. Phys. 89, 021001 (2017)
(b) Thermalization and chaos : see, e.g., Leading and Beyond Leading-Order Spectral Form Factor in Chaotic Quantum Many-Body Systems Across All Dyson Symmetry Classes, V. Kumar, T. Prosen, and D. Roy, Phys. Rev. X 16, 031019 (2026)
(c) Topological phases of matter : see, e.g., Topological aspects of periodically driven non-Hermitian Su-Schrieffer-Heeger model , V. M. Vyas and D. Roy, Phys. Rev. B 103, 075441 (2021)
(d) Spin noise spectroscopy : see, e.g., Detection of long-range coherence in driven hot atomic vapors by spin noise spectroscopy , R. Bag, S. Majumder, S. Chaudhuri , and D. Roy , Phys. Rev. B 114, L080305 (Letter) (2026)
