• A random matrix approach to RNA folding with interaction

In the matrix model of RNA [G Vernizzi, H Orland and A Zee, Phys. Rev. Lett. 94, 168103 (2005)] we introduce external interactions on n bases in the action of the partition function where $n \leq L$ and 𝐿 is the length of the polymer chain. The RNA structures found in the model can be separated into two regimes: (i) $0 \leq \alpha \leq 1$, $n &lt; L$ and $0 \leq \alpha &lt; 1$, $n = L$ where unpaired and paired base structures exist and (ii) $\alpha = 1$, $n = L$ with only completely paired base structures. Figures for the genus distribution functions show differences at small lengths. We consider the situation when the strength of external perturbation is different on different bases in the polymer chain.

• Matrix models of RNA folding with external interactions: A review

The matrix model of (simpliﬁed) RNA folding with an external linear interaction in the action of the partition function is reviewed. The important results for structure combinatorics of the model are discussed and analysed in terms of the already existing models.
