Research and Achievements

Ardalan’s research primarily focuses on string theory, particle physics, gravity, and noncommutative geometry. He is renowned for proposing para-string theory, constructing modular invariant partition functions for WZNW models using the orbifold method, classifying eleven-dimensional supergravity solutions with quotient structures, and discovering noncommutativity in D-branes of string theory. His work also extends to superstring theory and Yang-Mills theory.

He has authored over 55 scientific papers published in prestigious international journals, including Journal of Mathematical Physics (JMP), Physical Review, Physics Letters B, and International Journal of Modern Physics A. Notable publications include:
