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
Energy-time entangled photons provide new opportunities for controlling multiphoton absorption beyond classical limits. Here, we investigate biexciton generation in nanocrystal qua…
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…
Deep-learning atomistic semi-empirical pseudopotential model for nanomaterials
Kailai Lin, Matthew J. Coley-O'Rourke, Eran Rabani
The semi-empirical pseudopotential method (SEPM) has been widely applied to provide computational insights into the electronic structure, photophysics, and charge carrier dynamics…
Theoretical insights into the role of lattice fluctuations on the excited behavior of lead halide perovskites
Yoonjae Park, Rohit Rana, Daniel Chabeda +2
Lead halide perovskites have been extensively studied as a class of materials with unique optoelectronic properties. A fundamental aspect that governs optical and electronic behavi…
Simple Diagonal State Designs with Reconfigurable Real-Time Circuits
Yizhi Shen, Katherine Klymko, Eran Rabani +4
Unitary designs are widely used in quantum computation, but in many practical settings it suffices to construct a diagonal state design generated with unitary gates diagonal in the…
