TL;DR
This paper demonstrates the existence of an Efimov-like three-stranded DNA bound state at the melting point, described by a renormalization group limit cycle, suggesting Efimov physics can be observed in polymer systems.
Contribution
It introduces a nonperturbative RG approach to show Efimov-like states in three-stranded DNA, a novel application in polymer physics.
Findings
Existence of Efimov-like three-stranded DNA bound state.
Described by a renormalization group limit cycle.
Potential to test Efimov physics in polymer systems.
Abstract
We show that there exists an Efimov-like three strand DNA bound state at the duplex melting point and it is described by a renormalization group limit cycle. A nonperturbative RG is used to obtain this result in a model involving short range pairing only. Our results suggest that Efimov physics can be tested in polymeric systems.
