The prescriptions of the continuous time quantum random walk is applied to the single molecule, interpreted as an open quantum system, and the master equation driving its internal dynamics is built for a general distribution of random collision times. Over estimated long time scales, the dynamics of the coherence terms and the populations of the energy levels is evaluated analytically for relevant classes of non-Poissonian distributions of the collision times. Inverse power law relaxations and the inverse Zeno effect emerge over estimated long time scales and the stable asymptotic equilibrium configuration results to be independent of the distribution of the collision times. <\/jats:p>","DOI":"10.1142\/s1230161212500114","type":"journal-article","created":{"date-parts":[[2012,6,1]],"date-time":"2012-06-01T09:06:27Z","timestamp":1338541587000},"page":"1250011","source":"Crossref","is-referenced-by-count":2,"title":["Open System Approach to the Internal Dynamics of a Model Multilevel Molecule"],"prefix":"10.1142","volume":"19","author":[{"given":"F.","family":"Giraldi","sequence":"first","affiliation":[{"name":"Quantum Research Group, School of Chemistry and Physics and National Institute for Theoretical Physics, University of KwaZulu-Natal, Westville Campus, Durban, South Africa"},{"name":"Gruppo Nazionale per la Fisica Matematica, GNFM-INdAM, Via Madonna del Piano 10, I\u201350019 Sesto Fiorentino (FI), Italy"}]},{"given":"F.","family":"Petruccione","sequence":"additional","affiliation":[{"name":"Quantum Research Group, School of Chemistry and Physics and National Institute for Theoretical Physics, University of KwaZulu-Natal, Westville Campus, Durban, South Africa"}]}],"member":"219","published-online":{"date-parts":[[2012,6]]},"reference":[{"key":"rf1","volume-title":"The Theory of Open Quantum Systems","author":"Breuer H.
