Hamiltonian of mean force and a damped harmonic oscillator in an anisotropic medium
Marjan Jafari, Fardin Kheirandish
The quantum dynamics of a damped harmonic oscillator is investigated in the presence of an anisotropic heat bath. The medium is modeled by a continuum of three dimensional harmonic…

Quantum theory of a strongly-dissipative scalar field
Marjan Jafari, Fardin Kheirandish
The properties of a quantum dissipative scalar field is analyzed by Caldeira-Leggett model in strong-coupling regime. The Lagrangian of the total system is canonically quantized an…
