Ajit Srivastava

Prof. Ajit Srivastava is a faculty member at the University of Geneva, affiliated with the Faculty of Science and leading the Quantum Light Matter Lab. His research focuses on quantum optics, spin-valley physics, and topological aspects of light-matter interactions in atomically thin materials, particularly transition metal dichalcogenides such as WSe₂ and MoSe₂.

His research interests include:

• Quantum optics with 2D materials
• Spin-valley coupling and dynamics
• Excitons, polarons, and dipolar interactions in van der Waals heterostructures
• Topological and geometric effects in Bloch bands
• Quantum emitters and quantum information applications

Analysis of his recent publications (2015–2025) reveals a strong focus on the quantum optical properties of low-dimensional systems. His work bridges experimental and theoretical physics, exploring non-trivial band geometry, excitonic many-body states, and electrical control of valley and spin degrees of freedom. Key themes include the manipulation of quantum states via light, the emergence of topological phenomena in 2D systems, and the engineering of quantum emitters for information processing.
