Veniamin Blinov, Voislav Golo
TL;DR
This paper investigates the GHz-range acoustic properties of DNA, revealing parametric resonance and localized phonon modes caused by the DNA's structural randomness, advancing understanding of DNA's physical dynamics.
Contribution
It reports the discovery of parametric resonance and localized phonon modes in DNA at GHz frequencies, a novel insight into DNA's acoustic behavior.
Findings
Identification of parametric resonance in DNA at GHz frequencies
Detection of localized phonon modes due to sequence randomness
Insights into DNA's elastic properties at high frequencies
Abstract
We find a parametric resonance in the GHz range of the DNA dynamics, generated by pumping hypersound . There are localized phonon modes caused by the random structure of elastic modulii due to the sequence of base pairs.
