Formation of spectral triplets induced by parity deformation in a quantum dot-cavity system
Luisa M. Hurtado-Molina, Saravana Prakash Thirumuruganandham, Santiago Echeverri-Arteaga +1
In this work, we conduct an investigation on the optical emission properties of a pumped-dissipative QD-cavity system within the Lindblad master equation approach, where the cavity…
Pure dephasing vs. Phonon mediated off-resonant coupling in a quantum-dot-cavity system
Santiago Echeverri-Arteaga, Herbert Vinck-Posada, José M. Villas-Bôas +1
Pure dephasing is widely used in the literature to explain experimental observations on quantum dots in cavities. In many cases, its use is not enough and extra terms need to be "f…
A comparative study on different non-Hermitian approaches for modeling open quantum systems
Santiago Echeverri-Arteaga, Herbert Vinck-Posada, Edgar A. Gómez
In this paper, we test and compare the performance of two different theoretical methods that use anti-Hermitian terms for modeling open quantum systems. It is, the non-Hermitian qu…
The strange attraction phenomenon in cQED: the intermediate quantum coupling regime
Santiago Echeverri-Arteaga, Herbert Vinck-Posada, Edgar A. Gómez
We theoretically investigate the strange phenomenon of attraction between the cavity mode and the exciton mode that has been experimentally observed in a photonic crystal cavity. O…
Coexistence of weak and strong coupling with a quantum dot in a photonic molecule
S. Lichtmannecker, M. Kaniber, S. Echeverri-Arteaga +12
We study the emission from a molecular photonic cavity formed by two proximal photonic crystal defect cavities containing a small number (<3) of In(Ga)As quantum dots. Under strong…
Explanation of the intriguing quantum phenomenon of the off-resonant cavity mode emission
Santiago Echeverri-Arteaga, Herbert Vinck-Posada, Edgar A. Gómez
We theoretically investigate the unexpected occurrence of an extra emission peak that has been experimentally observed in off-resonant studies of cavity QED systems. Our results wi…
