Ring polymers in confined geometries
The investigation of a dilute solution of phantom ideal ring polymers and ring polymers with excluded volume interactions (EVI) in a good solvent confined in a slit geometry of two parallel repulsive walls and in a solution of colloidal particles of big size was performed.

interactions (EVI) in a good solvent confined in a slit geometry of two parallel repulsive walls and in a solution
of colloidal particles of big size was performed. Taking into account the correspondence between the field
theoretical φ⁴ O(n)-vector model in the limit n → 0 and the behaviour of long-flexible polymers in a good
solvent, the correspondent depletion forces and the forces which exert phantom ideal ring polymers and ring
polymers with EVI on the walls were obtained in the framework of the massive field theory approach at fixed
space dimensions d=3 up to one-loop order. Besides, taking into account the Derjaguin approximation, the
depletion forces between big colloidal particle and a wall and in the case of two big colloidal particles were
calculated. The obtained results indicate that phantom ideal ring polymers and ring polymers with EVI due to
the complexity of chain topology and for entropical re |
