Entanglement between distant atoms mediated by a hybrid quantum system consisting of superconducting flux qubit and resonators
Elaheh Afsaneh, Malek Bagheri Harouni, Marjan Jafari
A hybrid quantum system consisting of spatially separated two-level atoms is studied. Two atoms do not interact directly, but they are coupled via an intermediate system which is c…
Hamiltonian of mean force and dissipative scalar field theory
Marjan Jafari, Fardin Kheirandish
In the framework of the Hamiltonian of mean force, internal energy, free energy and entropy of a dissipative scalar field are obtained.
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…
Casimir Torque for a Perfectly Conducting Wedge: A Canonical Quantum Field Theoretical Approach
H. Razmi, S. M. Modarresi
The torque density per unit height exerted on a perfectly conducting wedge due to the quantum vacuum fluctuations (the Casimir torque) is obtained. A canonical quantum field theore…
A New Theorem on the Nonclassicality of States
F. Shähandeh, M. R. Bazrafkan
A new theorem on the non-classicality depth of states has been proved. We show that if exist for some value of the ordering parameter at some phase-spa…
