Dissipative response of driven bead-spring-dashpot chains (opens in new tab)

The work dissipated in pulling a polymer chain with internal friction is numerically calculated by considering a sequence of $N$ spring-dashpots tethered at one end and being pulled at the other using a harmonic trap via linear and symmetric protocols. The variation of the dissipation with the chain length, pulling trap stiffness, and the internal friction parameter are examined in detail for both the protocols. {While the dissipation increa...
