WebHere we predict that reversible heat transfers between a quantum-dot exciton and its phonon environment can be induced by laser pulses. We calculate the heat transfer when a quantum-dot exciton is driven by a chirped laser pulse. ... This performance is achieved by using the time-dependent laser-dressing of the exciton to control the heat ... WebWe also found that the phonon dressing of the SG kink by the ac driver, χ(t) , was necessary for the occurrence of a directed energy current in the SG equation. We show in the case of the double sine-Gordon (DSG) equation that the excitation of the internal mode, R(t) (where R(t) is the separation of the two subkinks that make up the DSG ...
WebJul 5, 2024 · The dressing phonon interaction plays a vital role in determin- ing the controlling parameters of quantum optical devices such as temperature sensors and all-optical switching applications. WebPhonon absorption and emission can modify the exciton dynamics [26, 27, 28] and afiect the e–ciency of the exciton energy transfer process. The efiect of a phonon bath on the energy transfer in the general case has been the subject of many theoretical investi-gations [29, 30, 31]. Due to the large deformation potentials in semiconductors ...
