| 08:00 - 09:00 Monthly Seminar Foundation of Physics Group From quantum non-locality to entanglement: Analysis in a unified ontological framework School PHYSICS Farmanieh Seminar Room ... 11:00 - 12:00 Quantum information biweekly journal club Photon Blockade Effect in Optomechanical Systems School NANO SCIENCES Photon Blockade Effect in Optomechanical Systems We analyze the photon statistics of a weakly driven optomechanical system and discuss the effect of photon blockade under single-photon strong coupling conditions. We present an intuitive interpretation of this effect in terms of displaced oscillator states and derive analytic expressions for the cavity excitation spectrum and the two-photon correlation function g(2)(0). Our results predict the appearance of nonclassical photon correlations in the combined strong coupling and sideband resolved regime and provide a first detailed understanding of photon-photon interactions in ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group The effect of interaction with phonons in bi-stability of electronic current and optical properties of quantum dots School PHYSICS Farmanieh Seminar Room ... 14:00 - 15:00 Weekly Seminar The effect of interaction with phonons in bi-stability of electronic current and optical properties of quantum dots School NANO SCIENCES The effect of interaction with phonons in bi-stability of electronic current and optical properties of quantum dots In this talk, a current carrying single or double-orbital quantum dot (QD) with electron-phonon interaction and its exposure to an incoming electromagnetic field is considered. In the Polaron regime and static limit, by approximating the electron-phonon interaction with an attractive Hubbard interaction, using the self-consistent Hartree-Fock (HF) approximation, we show that depending on the parameters, the system could be bi-stable. Also, using current conserving second order approximation for the single orbit ... 15:00 - 16:00 Weekly Seminar On the Effects of Finite Temperature and Magnetic Field on the Observables of Heavy Ion Collisions School PARTICLES AND ACCELERATORS The main focus of this talk is to investigate the effects of the created background magnetic field on some of the observables that are relevant in heavy ions experiments. Intense magnetic field may be produced during heavy ion collision and can not be neglected due to its large value. By pointing out to the collective behaviors in QGP, we have investigated the effects of collective modes on the shear viscosity which known as a remarkable macroscopic quantity. Thereafter we study the collective behaviors of fermionic particles in Quantum Electrodynamics (QED) theory in the condition of finite temperature and magnetic field. Eventually, we stud ... 16:30 - 18:00 Physics Colloquium Violation of the second law of thermodynamics and its consequences School PHYSICS Farmanieh, Seminar Room C ... |
