Theory of semi-flexible polymers
Shirish M. Chitanvis
We have mapped the physics of a system of semi-flexible inextensible polymers onto a complex Ginzburg-Landau field theory using techniques of functional integration. It is shown in…
Physics of polymer melts: A novel perspective
Shirish M. Chitanvis
We have mapped the physics of polymer melts onto a time-dependent Landau-Ginzburg field theory using techniques of functional integration. Time in the theory is simply a la…
Physics of rapidly expanding supercritical solutions: A first approach
Shirish M. Chitanvis
We consider the case when a supercritical fluid emerges at sonic speed from a small orifice in a high pressure chamber. The subsequent expansion causes a pressure drop and the flui…
Bosonization in arbitrary dimensions
Shirish M. Chitanvis
Using methods of functional integration, and performing simple Gaussian integrals, I show that an interacting system of electrons can be bosonized in arbitrary dimensions, in terms…
The onset of self-assembly
Shirish M. Chitanvis
We have formulated a theory of self-assembly based on the notion of local gauge invariance at the mesoscale. Local gauge invariance at the mesoscale generates the required long- ra…
