Some results on the spin-boson model

AuthorsGarcía-Ripoll, Juan José
Issue Date20-Aug-2014
CitationJQI Special Seminar (2014)
AbstractIn this talk I will discuss various applications and results on this well know model, which has found a new life in a variety of experimental systems that combine two-level systems with bosonic degrees of freedom, such as circuit-QED and trapped ions. The ideas I will discuss are related mainly to (i) the propagation of quantum information and correlations in the system and (ii) the existence of quantum phase transitions in regimes of >ultra-strong> coupling, where the counter-rotating terms of the spin-boson interaction play a relevant role. In passing I will review the theoretical and numerical tools we use to solve these problems.
