A homopolymer chain consisting of monomers interacting via a Square Well (SW) potential exhibits a freezing transition from expanded coil to compact crystalline conformations or transitions from coil conformations to collapsed globules and then to crystalline structures. Following the work of Taylor et al.[J. Chem. Phys. 131, 114907 (2009)] we study a homopolymer SW chain of length 156 N = mono...

A new kind of invariance by replication of a statistical measure of complexity is considered. We show that the set of energy eigenstates of the quantum infinite square well displays this particular invariance. Then, this system presents a constant complexity for all the energy eigenstates.
