Dynamics of Macromolecules in the Bath of Harmonic Oscillators
A.P. Blokhin, M.F. Gelin, and A.V. Uvarov

We consider the Hamilton dynamics of a Gaussian macromolecule immersed in the bath of harmonic oscillators. Such a bath is shown to insure the conventional dissipative dynamics for the center of mass co-ordinate of the macromolecule. It however produces the deterministic equations of motion for the internal (inter-bead distance) co-ordinates, whose evolution is influenced by additional bath-induced linear forces. It is argued that the harmonic bath with bilinear system-bath coupling is insufficient for inducing dissipative dynamics for a system consisting of several point particles.
Key words: gaussian macromolecule, hamiltonian dynamics, bath of linear oscillators
