Improving the Stability of the Hierarchical Equations of Motion for Open Quantum Systems with Strong Coupling to Structured Bosonic Baths
Salvatore Gatto, Samuel L. Rudge, Bokang Hou +2
The hierarchical equations of motion (HEOM) approach is one of the most powerful methods avail- able to simulate the dynamics of open quantum systems. Although the HEOM approach ha…
Full Quantum and Mixed Quantum--Classical Dynamics of Hot Exciton Cooling in Semiconductor Nanocrystals
Bokang Hou, Johan E. Runeson, Samuel L. Rudge +4
Hot-exciton relaxation in semiconductor nanocrystals (NCs) is often described using perturbative theories, but their accuracy is difficult to assess for realistic exciton--phonon H…
Selective Biexciton Generation Under Energy-Time Entangled Quantum Light in Quantum Dots
Kaiyue Peng, Chieh Tsao, Hendrik Utzat +1
Quantum light provides opportunities for controlling multiphoton absorption beyond classical limits. Here, we investigate biexciton generation in nanocrystal quantum dots driven by…
Photoluminescence Line Shapes of Nanocrystals: Contributions from First- and Second-Order Vibronic Couplings
Kaiyue Peng, Bokang Hou, Kailai Lin +3
We present a microscopic, parameter-free approach for computing the photoluminescence spectra of a single semiconductor nanocrystal. The method derives exciton-phonon coupling dire…
