Kremer-Grest melts prepared as described in "Facile equilibration of well-entangled semiflexible bead-spring polymer melts" [J. D. Dietz and R. S. Hoy, J. Chem. Phys. v. 156, article 014103 (2022)]
All these melts have monomer density rho = 0.85 and were prepared at a temperature kBT = 1 in Lennard-Jones units.
Note that the atom ids in the equilibrated states have been reordered so that they correspond to the final chain IDs [i.e. chain 1 has atom IDs 1-N, chain 2 has atom IDs (N+1)-2N, etc.] using this C++ code.
