Symmetric excitation and de-excitation of a cavity QED system
Olafur Jonasson, Chi-Shung Tang, Hsi-Sheng Goan +2
We calculate the time evolution of a cavity-QED system subject to a time dependent sinusoidal drive. The drive is modulated by an envelope function with the shape of a pulse. The s…
Stepwise introduction of model complexity in a generalized master equation approach to time-dependent transport
Vidar Gudmundsson, Olafur Jonasson, Thorsten Arnold +3
We demonstrate that with a stepwise introduction of complexity to a model of an electron system embedded in a photonic cavity and a carefully controlled stepwise truncation of the…
Optimal control for non-Markovian open quantum systems
Bin Hwang, Hsi-Sheng Goan
An efficient optimal-control theory based on the Krotov method is introduced for a non-Markovian open quantum system with a time-nonlocal master equation in which the control param…
Nonperturbative Approach to Circuit Quantum Electrodynamics
Olafur Jonasson, Chi-Shung Tang, Hsi-Sheng Goan +2
We outline a rigorous method which can be used to solve the many-body Schroedinger equation for a Coulomb interacting electronic system in an external classical magnetic field as w…
