Onirban Islam

Onirban Islam is a Researcher at the University of Potsdam's Department of Mathematics, specializing in mathematical physics. His work bridges differential geometry, microlocal analysis, and quantum field theory in curved spacetimes. Key affiliations include the University of Potsdam, where he investigates non-elliptic differential operators and their physical implications.

Research interests span three core areas:

• Global Analysis: Analysis of differential operators on manifolds using microlocal techniques, with applications to quantum field theory and general relativity.
• Semi-classical Gravity: Construction of Hadamard states in globally hyperbolic spacetimes with timelike boundaries.
• Spectral Geometry: Relativistic generalizations of trace formulas for wave and Dirac operators on stationary spacetimes.

His publications (2018–2024) focus on mathematical foundations of quantum field theory in curved backgrounds, including microlocal methods for propagators, trace formulas for Dirac operators, and entanglement entropy decay. No awards, students, or grants are documented.
