Garg is best known for formulating the Leggett–Garg inequality, named for Anthony James Leggett and himself, which is a mathematical inequality fulfilled by all macrorealistic physical theories.[2] He is also known for the Garg-Onuchic-Ambegaokar model of charge transfer. [3] In addition, he discovered the phenomenon of topological quenching of the tunnel splitting in a toy Hamiltonian for spin tunneling, [4] that was subsequently found experimentally in the magnetic molecule Fe8. [5] His current research interests center around coherent state path integrals, especially as they pertain to quantum and semi-classical phenomena associated with the orientation of quantum mechanical spin.
Garg is the author of a graduate physics textbook, Classical Electromagnetism in a Nutshell,[6] and an undergraduate text, Mathematics with a Scientific Sensibility. [7]
