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…
Heralded Emission Detection in InAs/ZnSe Quantum Dot Solids Using Time-Correlated Photons
Chieh Tsao, Xiang Li, Alex Hinkle +4
Harnessing quantum correlations between photons is an emerging frontier in optical spectroscopy, yet experimental demonstrations have largely remained limited to molecular systems…
Multi-Dimensional Photon-Correlations Reveal Triexciton Features in Single Perovskite Quantum Dots
Alex Hinkle, Chieh Tsao, Adam Duell +1
Lead-halide perovskite quantum dots (PQDs) are established quantum emitters with potential for entangled photon-pair generation via multiexciton cascades. However, the energetics a…
Enhancing Spectroscopy and Microscopy with Emerging Methods in Photon-Correlation and Quantum Illumination
Chieh Tsao, Haonan Ling, Alex Hinkle +4
Quantum optics has driven major advances in our ability to generate and detect correlations between individual photons. Its principles are now increasingly translated into nanoscal…
Stochastic Equilibrium Raman Spectroscopy (STERS)
Colburn Cobb-Bruno, Hendrik Utzat
We theoretically propose a new method in cavity- and surface-enhanced Raman spectroscopy (SERS) with improved temporal resolution in the measurement of stochastic Raman spectral fl…
