Аннотация:The intensive development of nanodevices acting as two-state systems has motivated the
search for nanoscale molecular structures whose dynamics are similar to those of bistable mechanical
systems, such as Euler arches and Duffing oscillators. Of particular interest are the molecular structures
capable of spontaneous vibrations and stochastic resonance. Recently, oligomeric molecules that
were a few nanometers in size and exhibited the bistable dynamics of an Euler arch were identified
through molecular dynamics simulations of short fragments of thermo-responsive polymers subject
to force loading. In this article, we present molecular dynamics simulations of short pyridine-furan
springs a few nanometers in size and demonstrated the bistable dynamics of a Duffing oscillator
with thermally-activated spontaneous vibrations and stochastic resonance.
