### OTHER CONTRIBUTIONS

With B. Banerjee, S. Balasubramanian, G. Ananthakrishnan et al found the existence of bimodality during the progression of cell cycles (2004)

With R. Gupta, G. Venketeswara, A.K. Sood & C.N.R. Rao first saw the anomalous temperature dependence of phonon lineshapes in charge-ordered manganites (2002)

Suggested a novel localizing phenomenon in doped manganites (1998)

With B.K. Chakraverty gave a simple universal criterion for behavior prediction of oxide superconductors (1997)

With K.V.R. Varma, G.N. Subbama & C.N.R. Rao discovered novel dielectric properties of glasses prepared by quenching melts of Bi-C-Sr-Cu-O cuprates (1989)

With M. Raj Lakshmi and H.R. Krishnamurthy first to calculate the dislocation structure within the framework of an order-parameter theory and incorporating thermal effects in it (1988)

With P. Coleman & P.W. Anderson showed that large anomalous Hall constants of mixed valent and Kondo lattice systems can be understood in terms of a simple resonant level Fermi liquid model (1985)

With P.W. Anderson & K.A. Mutalib proposed that superconducting critical temperature decreasing similarly with disorder for all systems with high critical temperature is a localization effect (1983)

With P.W. Anderson & E. Abrahams introduced the idea of an incoherence length L_{2} at which inelastic collision broadening equals electronic energy-level separation (1979)

Presented a many body theoretical method for calculating the effect of low energy fluctuations on the dynamic susceptibility (1974)
