Theta point (‘‘tricritical’’) region behavior for a polymer chain: Transition to collapse

摘要: The conformational space renormalization group method is generalized further to describe excluded volume effects in finite molecular weight polymers the theta point region where contributions from effective three‐body interactions become appreciable. theory builds upon our previous description of good solvent and uses t’Hooft‐Veltman style dimensional regularization along with (RG) determine general analytic structure measurable quantitites interest. Our formalism compared detail that employed field tricritical behavior. Although many results are qualitative agreement between two approaches, there some numerical differences. considers for chains fixed length, this introduces differences into scheme used theory, dictated by physical types systems considered. treatment length ...
