TL;DR
This paper investigates how terahertz (THz) electromagnetic fields affect the thermal melting and bubble formation in DNA molecules using a modified Peyrard-Bishop-Dauxois model.
Contribution
It introduces a model incorporating solvent effects and a sinusoidal THz field to study DNA behavior under electromagnetic influence.
Findings
THz fields can alter DNA melting transitions
Bubble formation is affected by field parameters
Thermal properties of DNA are modifiable with external fields
Abstract
We study the influence of a THz field on thermal properties of DNA molecules. A Peyrard- Bishop-Dauxois model with the inclusion of a solvent interaction term is considered. The THz field is included as a sinusoidal driven force in the equation of mo tion. We show how under certain field and system parameters, melting transition and bubble formation are modified.
