Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
Continuous and time-discrete non-Markovian system-reservoir interactions: Dissipative coherent quantum feedback in Liouville space
Oliver Kästle, Regina Finsterhoelzl, Andreas Knorr +1
Based on tensor network realizations of path integrals reducing exponential memory scaling to polynomial efficiency and a Liouville space implementation of a time-discrete quantum…
Strongly entangled system-reservoir dynamics with multiphoton pulses beyond the two-excitation limit: Exciting the atom-photon bound state
Kisa Barkemeyer, Andreas Knorr, Alexander Carmele
Within the matrix product state framework, we study the non-Markovian feedback dynamics of a two-level system interacting with the electromagnetic field inside a semi-infinite wave…
Unidirectional Quantum Transport in Optically Driven -type Quantum Dot Chains
Oliver Kaestle, Emil Vosmar Denning, Jesper Mørk +2
We predict a mechanism for achieving complete population inversion in a continuously driven InAs/GaAs semiconductor quantum dot featuring -type transitions. This highly nonequil…
Theory of the Coherent Response of Magneto-Excitons and Magneto-Biexcitons in Monolayer Transition Metal Dichalcogenides
Florian Katsch, Dominik Christiansen, Robert Schmidt +4
The recent accessibility of high quality, charge neutral monolayer transition metal dichalcogenides with narrow exciton linewidths at the homogeneous limit provides an ideal platfo…
Image dipoles approach to the local field enhancement in nanostructured Ag-Au hybrid devices
Christin David, Marten Richter, Andreas Knorr +2
We have investigated the plasmonic enhancement of the radiation field at various nanostructured multilayer devices, that may be applied in surface enhanced Raman spectroscopy. We a…
Exciton-Scattering-Induced Dephasing in Two-Dimensional Semiconductors
Florian Katsch, Malte Selig, Andreas Knorr
Enhanced Coulomb interactions in monolayer transition metal dichalcogenides cause tightly bound electron-hole pairs (excitons) which dominate their linear and nonlinear optical res…
Temporal evolution of low-temperature phonon sidebands in WSe monolayers
Roberto Rosati, Samuel Brem, Raül Perea-Causín +9
Low-temperature photoluminescence (PL) of hBN-encapsulated monolayer tungsten diselenide (WSe) shows a multitude of sharp emission peaks below the bright exciton. Some of them…
Quantized quasinormal mode description of non-linear cavity QED effects from coupled resonators with a Fano-like resonance
Sebastian Franke, Marten Richter, Juanjuan Ren +2
We employ a recently developed quantization scheme for quasinormal modes (QNMs) to study a nonperturbative open cavity-QED system consisting of a hybrid metal-dielectric resonator…
Dipolar and magnetic properties of strongly absorbing hybrid interlayer excitons in pristine bilayer MoS
Etienne Lorchat, Malte Selig, Florian Katsch +5
Van der Waals heterostructures composed of transition metal dichalcogenide monolayers (TMDs) are characterized by their truly rich excitonic properties which are determined by thei…
Screening of the quantum dot Förster coupling at small distances
Chelsea Carlson, Andreas Knorr, Stephen Hughes
We study the near-field energy transfer rates between two finite size quantum dot disks, generalizing the result of Förster coupling between two point dipoles. In particular, we de…
The ultrafast onset of exciton formation in 2D semiconductors
Chiara Trovatello, Florian Katsch, Nicholas J. Borys +11
The equilibrium and non-equilibrium optical properties of single-layer transition metal dichalcogenides (TMDs) are determined by strongly bound excitons. Exciton relaxation dynamic…
Entanglement robustness to excitonic spin precession in a quantum dot
Samir Bounouar, Gabriel Rein, Kisa Barkemeyer +9
A semiconductor quantum dot (QD) is an attractive resource to generate polarization-entangled photon pairs. We study the excitonic spin precession (flip-flop) in a family of QDs wi…
