Comment on "Memory Effects in an Interacting Magnetic Nanoparticle System" by Sun et. al, prl, 91, 167206 (2003)
S. Chakravarty, A. Frydman, M. Bandyopadhyay +2
In this Comment we report a phenomenon identical to that observed in ({Y. Sun, M. B. Salamon, K. Garnier and R. S. Averback, Phys. Rev. Lett. 91, 167206 (2003)}) for systems of NiF…
Arrested States of Solids
Madan Rao, Surajit Sengupta
Solids produced as a result of a fast quench across a freezing or a structural transition get stuck in long-lived metastable configurations of distinct morphology, sensitively depe…
First Passage Times and Time-Temperature-Transformation curves for Martensites
Madan Rao, Surajit Sengupta
Martensites are long-lived nonequilibrium structures produced following a quench across a solid state structural transition. In a recent paper (Phys. Rev. Lett. 78, 2168 (1997)), w…
Droplet Free Energy Functional for the Morphology of Martensites
Madan Rao, Surajit Sengupta
Martensites are metastable phases, possessing a characteristic morphology, usually formed during a fast quench accross a structural transition. We attempt to understand these morph…
