当一个DNA三重螺旋熔化时：Efimov状态的模拟
When a DNA Triple helix melts: An analog of the Efimov state
摘要：
DNA的碱基序列包含遗传密码，为了解码它，双螺旋DNA必须打开它的碱基对。最近的研究表明，人们可以使用第三条链来识别碱基序列，而不打开双螺旋，而是形成三螺旋。在这里，它是预测，这样的三链系统表现出不寻常的行为存在的三链束缚态的情况下，任何两个被绑定。这种现象类似于三粒子量子力学中的Efimov态。标度理论被用来证明Efimov连接。实空间重整化群和精确的数值计算被用来验证生物Efimov效应的预测。
英文摘要：
The base sequences of DNA contain the genetic code and to decode it a double helical DNA has to open its base pairs. Recent studies have shown that one can use a third strand to identify the base sequences without opening the double helix but by forming a triple helix. It is predicted here that such a three chain system exhibits the unusual behaviour of the existence of a three chain bound state in the absence of any two being bound. This phenomenon is analogous to the Efimov state in three particle quantum mechanics. A scaling theory is used to justify the Efimov connection. Real space renormalization group (RG), and exact numerical calculations are used to validate the prediction of a biological Efimov effect.
