Single-benzene fluorophores (SBFs) are exceptionally light-weight quantum emitters which have recently been shown to display Excited State Intramolecular Proton Transfer (ESIPT) an…
Revisiting crossed-correlated baths in open quantum systems simulated by HEOM or T-TEDOPA
Brieuc Le Dé, Etienne Mangaud, Alex W. Chin +1
Excited-state dynamics of open quantum systems is analyzed by the hierarchical equations of motion (HEOM) or the thermalized time-evolving density operator with orthogonal polynomi…
A comparison of different master equations for driven-dissipative dynamics in composite quantum systems: Dispersive readout in structured electromagnetic environments
Prakritish Gogoi, Angela Riva, Émile Cochin +1
Driven-dissipative qubit-resonator dynamics, which are the basis of most dispersive superconducting qubit measurement schemes, are often modeled with Lindblad master equations buil…
First-principles study of dispersive readout in circuit QED
