Numerically efficient density-matrix technique for modeling electronic transport in midinfrared quantum cascade lasers
S. Soleimanikahnoj, O. Jonasson, F. Karimi +1
We present a numerically efficient density-matrix model applicable to midinfrared quantum cascade lasers. The model is based on a Markovian master equation for the density matrix t…
Quantum Cascade Lasers: Electrothermal Simulation
S. Mei, Y. B. Shi, O. Jonasson +1
Book chapter on multiscale electrothermal simulation of midinfrared quantum cascade lasers. To appear in Handbook of Optoelectronic Device Modeling and Simulation, Taylor and Franc…
Modeling quantum cascade lasers: Coupled electron and phonon transport far from equilibrium and across disparate spatial scales
Y. B. Shi, S. Mei, O. Jonasson +1
Quantum cascade lasers (QCLs) are high-power coherent light sources in the midinfrared and terahertz parts of the electromagnetic spectrum. They are devices in which the electronic…
Partially coherent electron transport in terahertz quantum cascade lasers based on a Markovian master equation for the density matrix
O. Jonasson, F. Karimi, I. Knezevic
We derive a Markovian master equation for the single-electron density matrix, applicable to quantum cascade lasers (QCLs). The equation conserves the positivity of the density matr…
Dissipative transport in superlattices within the Wigner function formalism
O. Jonasson, I. Knezevic
We employ the Wigner function formalism to simulate partially coherent, dissipative electron transport in biased semiconductor superlattices. We introduce a model collision integra…
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…
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…
Time-dependent transport of electrons through a photon cavity
Vidar Gudmundsson, Olafur Jonasson, Chi-Shung Tang +2
We use a non-Markovian master equation to describe the transport of Coulomb interacting electrons through an electromagnetic cavity with one quantized photon mode. The central syst…
Quantum magneto-electrodynamics of electrons embedded in a photon cavity
Olafur Jonasson, Chi-Shung Tang, Hsi-Sheng Goan +2
We investigate the coupling between a quantized electromagnetic field in a cavity resonator and a Coulomb interacting electronic system in a nanostructure in an external magnetic f…
Correlated time-dependent transport through a 2D quantum structure
Vidar Gudmundsson, Chi-Shung Tang, Olafur Jonasson +2
We use a generalized master equation (GME) to describe the nonequilibrium magnetotransport of interacting electrons through a broad finite quantum wire with an embedded ring struct…
