Is small-world network disordered?
Soumen Roy, Somendra M. Bhattacharjee
Recent renormalization group results predict non self averaging behaviour at criticality for relevant disorder. However, we find strong self averaging(SA) behaviour in the critical…
Nonequilibrium Criticality at Shock Formation in Steady States
Sutapa Mukherji, Somendra M. Bhattacharjee
The steady state shock formation in processes like nonconserving asymmetric simple exclusion processes in varied situations is shown to be a nonequilibrium critical phenomenon. The…
Force induced triple point for interacting polymers
Sanjay Kumar, Debaprasad Giri, Somendra M. Bhattacharjee
We show the existence of a force induced triple point in an interacting polymer problem that allows two zero-force thermal phase transitions. The phase diagrams for three different…
Complete Phase Diagram of DNA Unzipping: Eye, Y-fork and triple point
Rajeev Kapri, Somendra M. Bhattacharjee, Flavio Seno
We study the unzipping of double stranded DNA (dsDNA) by applying a pulling force at a fraction from the anchored end. From exact analytical and numerical res…
Directed polymer in a random medium - an introduction
Somendra M. Bhattacharjee
This is a set of introductory lectures on the behaviour of a directed polymer in a random medium. Both the intuitive picture that helps in developing an understanding and systemati…
