The chain consists of N identical spherical monomers evolved according to Langevin dynamics. While neighboring monomers are coupled via harmonic springs, the non-neighboring monomers interact via a hard core and a short-ranged attractive potential. For a sufficiently small interaction range {\\lambda}, the system undergoes a first-order freezing transition from an expanded, disordered phase to a compact crystalline state.
