Theory of excitation transfer between two-dimensional semiconductor and molecular layers
Judith Specht, Eike Verdenhalven, Björn Bieniek +3
The geometry-dependent energy transfer rate from an electrically pumped inorganic semiconductor quantum well into an organic molecular layer is studied theoretically. We focus on F…
PsiQuaSP -- A library for efficient computation of symmetric open quantum systems
Michael Gegg, Marten Richter
In a recent publication we showed that permutation symmetry reduces the numerical complexity of Lindblad quantum master equations for identical multi-level systems from exponential…
Nanoplatelets as material system between strong confinement and weak confinement
Marten Richter
Recently, the fabrication of CdSe nanoplatelets became an important research topic. Nanoplatelets are often described as having a similar electronic structure as 2D dimensional qua…
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…
Coherent coupling of individual quantum dots measured with phase-referenced two-dimensional spectroscopy: photon echo versus double quantum coherence
Valentin Delmonte, Judith F. Specht, Tomasz Jakubczyk +7
We employ two-dimensional (2D) coherent, nonlinear spectroscopy to investigate couplings within individual InAs quantum dots (QD) and QD molecules. Swapping pulse ordering in a two…
Dark and bright exciton formation, thermalization, and photoluminescence in monolayer transition metal dichalcogenides
Malte Selig, Gunnar Berghäuser, Marten Richter +3
The remarkably strong Coulomb interaction in atomically thin transition metal dichalcogenides (TMDs) results in an extraordinarily rich many-particle physics including the formatio…
