  Title Thermodynamic formalism for dissipative quantum walks Type Journal Article
  Year 2012 Publication PHYSICAL REVIEW A Abbreviated Journal Phys. Rev. A  
  Volume 86 Issue 3 Pages 8 pp  
  Keywords  
  Abstract We consider the dynamical properties of dissipative continuous-time quantum walks on directed graphs. Using a large-deviation approach we construct a thermodynamic formalism allowing us to define a dynamical order parameter, and to identify transitions between dynamical regimes. For a particular class of dissipative quantum walks we propose a quantum generalization of the the classical PageRank vector, used to rank the importance of nodes in a directed graph. We also provide an example where one can characterize the dynamical transition from an effective classical random walk to a dissipative quantum walk as a thermodynamic crossover between distinct dynamical regimes.
