  Effective and fast convergence toward an equilibrium state for long-chain
polymer melts is realized by a hybrid method coupling molecular dynamics and
the elastic continuum. The required simulation time to achieve the equilibrium
state is reduced drastically compared with conventional equilibration methods.
The polymers move on a wide range of the energy landscape due to large-scale
fluctuation generated by the elastic continuum. A variety of chain structures
is generated in the polymer melt which results in the fast convergence to the
equilibrium state.
