Relation Between Dephasing and Renormalization Phenomena in Quantum Two-Level Systems

  • A. Shnirman
  • G. Schön


We observe that experimental conditions, for example, details of the initial state preparation, determine to what extent the environment leads to dephasing or to renormalization effects. We analyze an exactly solvable limit of the spin-boson model where the relation between both can be demonstrated explicitly.
