Abstract
We study the influence of a terahertz field on thermal properties of DNA molecules. A Peyrard-Bishop-Dauxois model with the inclusion of a solvent interaction term is considered. The terahertz field is included as a sinusoidal driven force in the equation of motion. We show how under certain field and system parameters, the melting transition and bubble formation are modified.
摘要
我们研究太赫兹场对DNA分子热性质的影响。考虑了一个包含溶剂相互作用项的佩拉尔-毕晓普-多克索模型。太赫兹场作为简谐驱动力包含在运动方程中。我们展示了在特定的场和系统参数下，熔解转变和气泡形成是如何被改变的。
