Theory of tricriticality for miscut surfaces
Somendra M. Bhattacharjee
We propose a theory for the observed tricriticality in the orientational phase diagram of Si(113) misoriented towards [001]. The systems seems to be at or close to a very special p…
Infinite number of exponents for a spin glass transition
Sutapa Mukherji\cite, Somendra M. Bhattacharjee
We consider the behavior of the overlap of paths at the spin glass transition for a directed polymer in a random medium. We show that an infinite number of exponents i…
Scaling of fluctuation for Directed polymers with random interaction
Sutapa Mukherji, Somendra M. Bhattacharjee, A. Baumgärtner
Using a finite size scaling form for reunion probability, we show numerically the existence of a binding-unbinding transition for Directed polymers with random interaction. The cas…
Polymers with Randomness: Phases and Phase Transitions
Somendra M. Bhattacharjee, Sutapa Mukherji
We discuss various aspects of the randomly interacting directed polymers with emphasis on the phases and phase transition. We also discuss the behaviour of overlaps of directed pat…
Fifty Years of the Exact Solution of the Two-Dimensional Ising Model by Onsager
Somendra M. Bhattacharjee, Avinash Khare
The exact solution of the two-dimensional Ising model by Onsager in 1944 represents one of the landmarks in theoretical physics. On the occassion of the fifty years of the exact so…
Protein Folding and Spin Glass
S. Suresh Rao, Somendra M. Bhattacharjee
We explicitly show the connection between the protein folding problem and spin glass transition. This is then used to identify appropriate quantities that are required to describe…
