Our approach complements and extends recent results that were based on Chebyshev's integral inequality \cite{BA19}. The method developed here correlates arbitrary phase-space functions at arbitrary points in phase space, including multimode scenarios and higher-order correlations. Furthermore, our approach provides necessary and sufficient nonclassicality criteria, applies to phase-space functions beyond s-parametrized ones, and is accessible in experiments. To demonstrate the power of our technique, the quantum characteristics of discrete- and continuous-variable, single- and multimode, as well as pure and mixed states are certified only employing second-order correlations and Husimi functions, which always resemble a classical probability distribution. Moreover, nonlinear generalizations of our approach are studied. Therefore, a versatile and broadly applicable framework is devised to uncover quantum properties in terms of matrices of phase-space distributions. article_number: '343' author: - first_name: Martin full_name: Bohmann, Martin last_name: Bohmann - first_name: Elizabeth full_name: Agudelo, Elizabeth last_name: Agudelo - first_name: Jan full_name: Sperling, Jan id: '75127' last_name: Sperling orcid: 0000-0002-5844-3205 citation: ama: Bohmann M, Agudelo E, Sperling J.

A commonly used approach to describe theoretical properties includes a phenomenological single-mode equation that complements the equation for the nonlinear optical response (interband polarization) of the semiconductor. Here, we show how to replace the single-mode equation by a fully predictive transfer function method that, in contrast to the single-mode equation, accounts for propagation, retardation, and pulse-filtering effects of the incident light field traversing the distributed Bragg reflector (DBR) mirrors, without substantially increasing the numerical complexity of the solution. As examples, we use cavities containing GaAs quantum wells and transition-metal dichalcogenides (TMDs). article_number: G112 author: - first_name: M. full_name: Carcamo, M. last_name: Carcamo - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: R. full_name: Binder, R. last_name: Binder citation: ama: Carcamo M, Schumacher S, Binder R.

The cluster adsorption is found to be dominated by van der Waals forces. The electronic structure and in particular the excitation energies of the bare clusters and the TiO2/graphene composites are found to vary largely in dependence on the size of the respective constituents. This holds in particular for the energy and the spatial localization of the highest occupied and lowest unoccupied molecular orbitals. In addition to a substantial gap narrowing, a pronounced separation of photoexcited electrons and holes is predicted in some instances. This is expected to prolong the lifetime of photoexcited carriers. Altogether, TiO2/graphene composites are predicted to be promising photocatalysts with improved electronic and photocatalytic properties compared to bulk TiO2. article_type: original author: - first_name: Sabuhi full_name: Badalov, Sabuhi id: '78800' last_name: Badalov orcid: 0000-0002-8481-4161 - first_name: René full_name: Wilhelm, René last_name: Wilhelm - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 citation: ama: Badalov S, Wilhelm R, Schmidt WG.

In inhomogeneous ensembles a macroscopic optical polarization decays rapidly due to dephasing, which, however, is reversible in photon echoes carrying complete information about the coherent ensemble dynamics. Control of the echo emission time is mandatory for applications. Here, we propose a concept to reach this goal. In a two-pulse photon echo sequence, we apply an additional resonant control pulse with multiple of 2π area. Depending on its arrival time, the control slows down dephasing or rephasing of the exciton ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum dots that the photon echo emission time can be retarded or advanced by up to 5 ps relative to its nominal appearance time without control. This versatile protocol may be used to obtain significantly longer temporal shifts for suitably tailored control pulses. article_number: '228' author: - first_name: Alexander N. full_name: Kosarev, Alexander N. last_name: Kosarev - first_name: Hendrik full_name: Rose, Hendrik id: '55958' last_name: Rose orcid: 0000-0002-3079-5428 - first_name: Sergey V. full_name: Poltavtsev, Sergey V. last_name: Poltavtsev - first_name: Matthias full_name: Reichelt, Matthias id: '138' last_name: Reichelt - first_name: Christian full_name: Schneider, Christian last_name: Schneider - first_name: Martin full_name: Kamp, Martin last_name: Kamp - first_name: Sven full_name: Höfling, Sven last_name: Höfling - first_name: Manfred full_name: Bayer, Manfred last_name: Bayer - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Ilya A. full_name: Akimov, Ilya A. last_name: Akimov citation: ama: Kosarev AN, Rose H, Poltavtsev SV, et al.

With their additional degree of freedom, the vorticity, they have been widely investigated in many physical systems and different materials for fundamental interest and for applications in data storage and information processing. Vortices have also been observed in non-equilibrium exciton-polariton condensates in planar semiconductor microcavities. There they appear spontaneously or can be created and pinned in space using ring-shaped optical excitation profiles. However, using the vortex state for information processing not only requires creation of a vortex but also efficient control over the vortex after its creation. Here we demonstrate a simple approach to control and switch a localized polariton vortex between opposite states. In our scheme, both the optical control of vorticity and its detection through the orbital angular momentum of the emitted light are implemented in a robust and practical manner. author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Xuekai full_name: Ma, Xuekai last_name: Ma - first_name: Bernd full_name: Berger, Bernd last_name: Berger - first_name: Marc full_name: Aßmann, Marc last_name: Aßmann - first_name: Rodislav full_name: Driben, Rodislav last_name: Driben - first_name: Christian full_name: Schneider, Christian last_name: Schneider - first_name: Sven full_name: Höfling, Sven last_name: Höfling - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 citation: ama: Meier T, Ma X, Berger B, et al.

The materials possess fine-leaved structures at their particle surface (nanowall hollow micro spheres). Morphology control is achieved by citric acid used as an additive in variable relative quantities during the synthesis. The structure formation is studied by various time-dependent ex situ methods, such as scanning electron microscopy, x-ray diffraction, and Raman spectroscopy. The fine-leaved surface structure is characterized by high-resolution transmission electron microscopy techniques (HRTEM, STEM), using a high-angle annular dark field detector, as well as by differential phase contrast analysis. In-depth structural characterization of the nanowalls by drop-by-drop ex situ FE-SEM analysis provides insight into possible structure formation mechanisms. Further investigation addresses the thermal stability of the particle morphology and the enhancement of the surface-to-volume ratio by heat treatment (examined by N2 physisorption). article_type: original author: - first_name: Katja full_name: Engelkemeier, Katja id: '21743' last_name: Engelkemeier - first_name: Jörg full_name: Lindner, Jörg id: '20797' last_name: Lindner - first_name: Julius full_name: Bürger, Julius id: '46952' last_name: Bürger - first_name: Kathrin full_name: Vaupel, Kathrin last_name: Vaupel - first_name: Marc full_name: Hartmann, Marc last_name: Hartmann - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Engelkemeier K, Lindner J, Bürger J, et al.
