报告摘要：
Fluctuation-dominated phase ordering (FDPO) refers to a steady state in which the magnitude of long-range order varies strongly owing to fluctuations, and to the associated coarsening phenomena during the approach to steady state. Strong fluctuations lead to a number of interesting phenomena, including a cusp singularity in the scaled correlation function, implying the breakdown of the Porod Law. First identified in a nonequilibrium system of passively sliding particles on a fluctuating surface, fluctuation-dominated order also occurs in several other systems, including an equilibrium Ising model with long-range interactions.
报告人简介：
Prof. Mustansir Barma is a theoretical physicist at the Tata Institute of Fundamental Research, Hyderabad.After completing his Ph. D. from Stony Brook in 1974 and working as a postdoc at MichiganState University, he joined the Tata Institute of Fundamental Research (TIFR) Mumbai in1976. Except for extended stays at Cornell University (1982-84) and Oxford University(1991-92), he has been at TIFR throughout. He was appointed Director of TIFR between 2007 and 2014. Currently he is Professor Emeritus at the new campus of TIFR in Hyderabad where he holds the DAE Homi Bhabha Chair Professorship.
Prof. Barma served as Chair of the C3 Commission of Statistical Physics of the IUPAP between 2002 and 2005 and as Vice-president of the IUPAP between 2008 and 2014.He is a Fellow of the three national academies of science in India, and of TWAS. He is the recipient of several awards including the S S Bhatnagar Prize, and was honoured with the Padma Shri by the Government of India.
Prof. Barma’s research has focused on cooperative effects in interacting particle systems, both in and out of equilibrium. In particular, his recent work has focused on various aspects of phase transitions, disordered systems and the dynamics of nonequilibrium systems.
