Anomalous temperature relaxation for polymeric chains

We analyse the temperature relaxation phenomena of small polymeric chains in contact with a thermal reservoir. We simulate the chains in a fluid [1], and we show that they reproduce a behaviour predicted by recent theoretical investigations [2]. The temperature decay reveals the existence of an anomalous cooling in which the temperature may oscillate [2]. This effect is a consequence of collective behaviour of the monomers in the chain, which builds up correlation [3,4]. This anomalous behaviour however, does not violated the second law of thermodynamics [5]. We analyse as well the scaling [4,6] dynamical properties of the chains.\\
