Designing thermal diode and heat pump based on DNA nanowire: Multifractal approach

The management of heat flow in DNA nano wire was considered. Thermal diode effect in DNA and the domain of its appearance dependent to system parameters have been detected. The appearance of directed thermal flow in thermodynamic sizes proposes the possibility of designing the macroscopic thermal rectifier. By applying driven force, pumping effect has been also observed. The resonance frequency of DNA and threshold amplitudes of driving force for attaining permanent pumping effect have been detected. Forasmuch as detecting negative differential thermal resistance (NDTR) phenomenon, DNA can act as a thermal transistor. By using an analytical parallel investigation based on Rényi spectrum analysis, threshold values to transition to NDTR and pumping regimes have been detected.
