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…
Quantum Otto cycle in the Anderson impurity model
Salvatore Gatto, Alessandra Colla, Heinz-Peter Breuer +1
We study the thermodynamic performance of a periodic quantum Otto cycle operating on the single-impurity Anderson model. Using a decomposition of the time-evolution generator based…
Unraveling Exciton Trap Dynamics and Nonradiative Loss Pathways in Quantum Dots via Atomistic Simulations
Bokang Hou, Salvatore Gatto, Samuel L. Rudge +3
Surface defects in colloidal quantum dots are a major source of nonradiative losses, yet the microscopic mechanisms underlying exciton trapping and recombination remain elusive. He…
Quantum thermodynamics of the spin-boson model using the principle of minimal dissipation
Salvatore Gatto, Alessandra Colla, Heinz-Peter Breuer +1
A recently developed approach to the thermodynamics of open quantum systems, on the basis of the principle of minimal dissipation, is applied to the spin-boson model. Employing a n…
