Chaotic Behavior of Quantum Cascade Lasers at Ignition
D. E. Önder, A. A. S. Kalaee, D. O. Winge +1
The ignition of Quantum Cascade Lasers can occur from a state of oscillating fie ld domains. Here, the interplay between lasing and the kinetics of traveling dom ain boundaries pro…
Violating the Thermodynamic Uncertainty Relation in the Three-Level Maser
Alex Arash Sand Kalaee, Andreas Wacker, Patrick P. Potts
Nanoscale heat engines are subject to large fluctuations which affect their precision. The Thermodynamic Uncertainty Relation (TUR) provides a trade-off between output power, fluct…
Positivity of entropy production for the three-level maser
Alex Arash Sand Kalaee, Andreas Wacker
Entropy production is a key concept of thermodynamics and allows one to analyze the operation of engines. For the Scovil-Schulz-DuBois heat engine, the archetypal three-level therm…
Electron-Extraction from Excited Quantum Dots with Higher Order Coulomb Scattering
Alex Arash Sand Kalaee, Andreas Wacker
The electron kinetics in nanowire-based hot-carrier solar cells is studied, where both relaxation and extraction are considered concurrently. Our kinetics is formulated in the many…
