Holographic influence functional and its application to decoherence induced by quantum critical theories

Understand

The dynamics of a particle influenced by strongly-coupled quantum critical theories is studied by the holographic approach.

• A real-time prescription for the AdS/CFT correspondence in the context of nonequilibrium physics is proposed from mainly the field theoretic consideration, and the associated holographic influence functional is obtained.
• We then study the decoherence dynamics of a particle induced by the quantum critical theories with a dynamical exponent $z$.
• We find that as $z$ increases, the decoherence effect becomes less significant.
