Title: Phase transitions: Water to magnetic glass

Speaker: Dr. Praveen Chaddah, UGC-DAE Consortium for Scientific Research, Indore

Abstract: There is general agreement that water is essential to the occurrence of life, and that we survive on Earth because water exists in all its three phases, transforming through 1st order transitions. Survival of some forms of life does depends on avoiding these 1st order transitions. Glass is also formed by avoiding a 1st order transition and has, like steel and concrete, shaped our civilization. I shall discuss our studies at Indore that have used very high magnetic fields and very low temperatures to understand why a material would avoid a 1st order magnetic transition and form a magnetic glass.
