In this theoretical study, we characterize the structural properties of a novel material, i.e., F-doped RbTiOPO4 (RbTiPO4F, RTP:F), and discuss aspects of its electrochemical performance in Rb-ion batteries (RIBs) using density functional theory (DFT). According to our calculations, RTP:F is expected to retain the so-called KTiOPO4 (KTP)-type structure, with lattice parameters of 13.236 Å, 6.616 Å, and 10.945 Å. Due to the doping with F, the crystal features eight extra electrons per unit cell, whereby each of these electrons is trapped by one of the surrounding Ti atoms in the cell. Notably, the ground state of the system corresponds to a ferromagnetic spin configuration (i.e., S=4). The deintercalation of Rb leads to the oxidation of the Ti atoms in the cell (i.e., from Ti3+ to Ti4+) and to reduced magnetic moments. The material promises interesting electrochemical properties for the cathode: rather high average voltages above 2.8 V and modest volume shrinkages below 13% even in the fully deintercalated case are predicted.' article_number: '5' author: - first_name: Adriana full_name: Bocchini, Adriana id: '58349' last_name: Bocchini orcid: 0000-0002-2134-3075 - first_name: Yingjie full_name: Xie, Yingjie last_name: Xie - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Uwe full_name: Gerstmann, Uwe id: '171' last_name: Gerstmann orcid: 0000-0002-4476-223X citation: ama: Bocchini A, Xie Y, Schmidt WG, Gerstmann U.

Wave-mixing experiments are often described with semiclassical models, where the light is modeled classically and the material quantum mechanically. Here, however, we use a fully quantized model, where the light is given by a quantum state of light. Quantum light involves more degrees of freedom than classical light as e.g., its photon statistics and quantum correlations, which is a promising resource for quantum devices, such as quantum memories. The light-matter interaction is treated with a Jaynes-Cummings type model and the quantum field is given by a single mode since the quantum dots are embedded in a microcavity. We present numerical simulations of the four-wave-mixing response of a homogeneous system for pulse sequences and find a significant dependence of the result on the photon statistics of the incident pulses. The model constitutes a problem with a large state space which arises from the frequency distribution of the transition energies of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum light mode. Here we approximate the dynamics by summing over individual quantum dot-microcavity systems. Photon echoes arising from the excitation with different quantum states of light are simulated and compared. article_number: 124190H author: - first_name: Hendrik full_name: Rose, Hendrik id: '55958' last_name: Rose orcid: 0000-0002-3079-5428 - first_name: S. full_name: Grisard, S. last_name: Grisard - first_name: A.

The situation is, however, different in solid-state systems as it has been demonstrated that due to collisions with neighboring atomic cores of the crystal lattice strong HHG can be generated even by elliptically- and circularly-polarized laser fields. Here we apply PG to solid-state systems and find that the conventional PG technique is inefficient for the generation of isolated ultrashort harmonic pulse bursts. In contrast, we demonstrate that a polarization-skewed laser pulse is able to confine the harmonic emission to a time window of less than one-tenth of the laser cycle. This method provides a novel way to control HHG and to generate isolated attosecond pulses in solids. article_number: '18862' author: - first_name: Xiaohong full_name: Song, Xiaohong last_name: Song - first_name: Shidong full_name: Yang, Shidong last_name: Yang - first_name: Guifang full_name: Wang, Guifang last_name: Wang - first_name: Jianpeng full_name: Lin, Jianpeng last_name: Lin - first_name: Liang full_name: Wang, Liang last_name: Wang - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Weifeng full_name: Yang, Weifeng last_name: Yang citation: ama: Song X, Yang S, Wang G, et al.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles. article_number: '1387' author: - first_name: B. full_name: Jonas, B. last_name: Jonas - first_name: Dirk Florian full_name: Heinze, Dirk Florian id: '10904' last_name: Heinze - first_name: E. full_name: Schöll, E. last_name: Schöll - first_name: P. full_name: Kallert, P. last_name: Kallert - first_name: T. full_name: Langer, T. last_name: Langer - first_name: S. full_name: Krehs, S. last_name: Krehs - first_name: A. full_name: Widhalm, A. last_name: Widhalm - first_name: Klaus full_name: Jöns, Klaus id: '85353' last_name: Jöns - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: Artur full_name: Zrenner, Artur id: '606' last_name: Zrenner orcid: 0000-0002-5190-0944 citation: ama: Jonas B, Heinze DF, Schöll E, et al.

In this work, the formation of (defect) bound polarons in lithium niobate is studied by ab initio molecular dynamics. The calculations show a broad scatter of polaron formation times. Rising temperature increases the share of trajectories with long formation times, which leads to an overall increase of the average formation time with temperature. However, even at elevated temperatures, the average formation time does not exceed the value of 100 femtoseconds, i.e., a value close to the time measured for free, i.e., self-trapped polarons. Analyzing individual trajectories, it is found that the time required for the structural relaxation of the polarons depends sensitively on the excitation of the lithium niobate high-frequency phonon modes and their phase relation. author: - first_name: Marvin full_name: Krenz, Marvin id: '52309' last_name: Krenz - first_name: Uwe full_name: Gerstmann, Uwe id: '171' last_name: Gerstmann orcid: 0000-0002-4476-223X - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 citation: ama: Krenz M, Gerstmann U, Schmidt WG.

Furthermore, we create so-called gray tracking in KTP and investigate the ionic conductivity in theses areas. A local unintended reduction of the ionic conductivity is observed in the gray-tracked regions, which also induce additional optical absorption in the material. We show that a thermal treatment in an oxygen-rich atmosphere removes the gray tracking and brings the ionic conductivity as well as the optical transmission back to the original level. These studies can help to choose the best material and treatment for specific applications. author: - first_name: Laura full_name: Padberg, Laura id: '40300' last_name: Padberg - first_name: Viktor full_name: Quiring, Viktor last_name: Quiring - first_name: Adriana full_name: Bocchini, Adriana id: '58349' last_name: Bocchini orcid: 0000-0002-2134-3075 - first_name: Matteo full_name: Santandrea, Matteo id: '55095' last_name: Santandrea orcid: 0000-0001-5718-358X - first_name: Uwe full_name: Gerstmann, Uwe id: '171' last_name: Gerstmann orcid: 0000-0002-4476-223X - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 citation: ama: 'Padberg L, Quiring V, Bocchini A, et al.
