[pub 1] Datta also worked at the Jet Propulsion laboratory (JPL) in Pasadena, California, as a pre-doctoral NASA research associate of Robert Somoano.
He also collaborated with Carl H. Brans at Loyola University New Orleans on a gravitational problem of frame dragging and worked with John Perdew on the behavior of charge density waves in jellium.
Datta was a NSF post-doctoral fellow with Marvin Silver and studied charge propagation in non-crystalline systems[pub 2] at the University of North Carolina in Chapel Hill.
He collaborated with several laboratories involved with the early discoveries of high temperature superconductivity, especially the team at NRL, led by Donald U Gubser and Stuart Wolf.
This research group at USC was the also first to observe [pub 4] (i) bulk Meissner effect in Tl-copper oxides and thus confirm the discovery by Allen Herman's team at the University of Arkansas of high temperature superconductivity in these compounds.
