Effective gibbs state for averaged observables

HIGHLIGHTS

  • who: Alexander Evgen`evich Teretenkov from the Department of Mathematical Methods for Quantum Technologies, Steklov Mathematical Institute of Russian have published the research work: Effective Gibbs State for Averaged Observables, in the Journal: Entropy 2022, 24, 1144. of /2022/
  • what: The authors show that there are a lot of similarities between this effective Hamiltonian and the mean force Hamiltonian which suggests a generalization of quantum thermodynamics including both cases. The authors show that the zeroth and the first term of the expansion coincide with the RWA Hamiltonian and, in particular, are temperature independent. The authors . . .
