Quantum-optical spectroscopy of a two-level system using an electrically driven micropillar laser as resonant excitation source
Sören Kreinberg, Tomislav Grbešic, Max Strauß +6
Two-level emitters constitute main building blocks of photonic quantum systems and are model systems for the exploration of quantum optics in the solid state. Most interesting is t…
Correlations of cascaded photons: An analytical study in the two-photon Mollow regime
Alexander Carmele, Samir Bounouar, Max Strauß +2
Mollow physics in the two-photon regime shows interesting features such as path-controlled time-reordering of photon pairs without the need to delay them. Here, we calculate analyt…
Quantum cascade driving: Dissipatively mediated coherences
Shahabedin C. Azizabadi, Nicolas L. Naumann, Manuel Katzer +2
Quantum cascaded systems offer the possibility to manipulate a target system with the quantum state of a source system. Here, we study in detail the differences between a direct qu…
Collective enhancements in many-emitter phonon lasing
Leon Droenner, Nicolas L. Naumann, Julia Kabuss +1
We investigate theoretically the many-emitter phonon laser based on optically driven semiconductor quantum dots within an acoustic nanocavity. We map the phonon laser Hamiltonian t…
Boundary driven Heisenberg-chain in the long-range interacting regime: Robustness against far from equilibrium effects
Leon Droenner, Alexander Carmele
We investigate the Heisenberg XXZ-chain with long-range interactions in the Z-dimension. By applying two magnetic boundary reservoirs we drive the system out of equilibrium and ind…
Superradiant to subradiant phase transition in the open system Dicke model: Dark state cascades
Michael Gegg, Alexander Carmele, Andreas Knorr +1
Collectivity in ensembles of atoms gives rise to effects like super- and subradiance. While superradiance is well studied and experimentally accessible, subradiance remains elusive…
Intensified antibunching via feedback-induced quantum interference
Yiping Lu, Nicolas L. Naumann, Javier Cerrillo +3
We numerically show that time delayed coherent feedback controls the statistical output characteristics of driven quantum emitters. Quantum feedback allows to enhance or suppress a…
Unraveling Mirror Properties in Time-Delayed Quantum Feedback Scenarios
Fabian M. Faulstich, Manuel Kraft, Alexander Carmele
We derive in the Heisenberg picture a widely used phenomenological coupling element to treat feedback effects in quantum optical platforms. Our derivation is based on a microscopic…
