The quantum network as an environment
Erik Aurell, Roberto Mulet, Jan Tuziemski
quantum system interacting with other quantum systems experiences these other systems asan effective environment. The environment is the result of integrating out all the other deg…
The Vernon transform and its use in quantum thermodynamics
Erik Aurell, Jan Tuziemski
The thermodynamics of a quantum system interacting with an environment that can be assimilated to a harmonic oscillator bath has been extensively investigated theoretically. In rec…
Symmetries of quantum evolutions
Giulio Chiribella, Erik Aurell, Karol Życzkowski
A cornerstone of quantum mechanics is the characterisation of symmetries provided by Wigner's theorem. Wigner's theorem establishes that every symmetry of the quantum state space m…
An operator derivation of the Feynman-Vernon theory, with applications to the generating function of bath energy changes and to anharmonic baths
Erik Aurell, Ryoichi Kawai, Ketan Goyal
We present a derivation of the Feynman-Vernon approach to open quantum systems in the language of super-operators. We show that this gives a new and more direct derivation of the g…
