Borregaard, J. (author), Pichler, Hannes (author), Schröder, Tim (author), Lukin, Mikhail D. (author), Lodahl, Peter (author), Sørensen, Anders S. (author)We propose a novel one-way quantum repeater architecture based on photonic tree-cluster states. Encoding a qubit in a photonic tree cluster protects the information from transmission loss and enables long-range quantum communication through a chain of repeater stations. As opposed to conventional approaches that are limited by the two-way...journal article 2020

(author), Rupprecht, Christoph D.D. (author), Tukker, Arnold (author), Wennersten, Ronald (author)Urban consumption patterns and lifestyles are increasingly important for the sustainability of cities today and in the future. However, considerations of consumption issues, social norms, behaviour and lifestyles within current urban sustainability research and practices are limited. Much untapped potential for the reduction of the...journal article 2019

Picek, Oliver (author), Schröder, E. (author)We use data from the World Input-Output Database to fit a closed multiregional input-output model in order to estimate the size of spillover effects of Germany's final demand on GDP, employment and the trade balance in Southern European countries. We find that spillover effects are rather small. Germany alone will hardly make a significant...journal article 2018

Schröder, E. (author)The article uses a demand-constrained small-open-economy model in the tradition of Keynes and Kalecki to study the effects of offshoring on aggregate demand and domestic employment. Offshoring is represented as labor-saving import-using technical change. The results depend on the behavior of the markup on unit costs. If higher markups absorb...journal article 2018

Jayadev, Arjun (author), Mason, J. W. (author), Schröder, E. (author)The quantitative growth and increased social prominence of financial institutions and markets can be usefully seen in terms of the constraints or 'discipline' they impose on other private and public decision makers. The role of finance in allocating real resources may be less important than its role in supporting the claims and authority of...journal article 2018

(author), Weinans, Harrie (author), Jahr, H. (author), Zadpoor, A.A. (author)An ideal bone substituting material should be bone-mimicking in terms of mechanical properties, present a precisely controlled and fully interconnected porous structure, and degrade in the human body to allow for full regeneration of large bony defects. However, simultaneously satisfying all these three requirements has so far been highly...journal article 2017

Schanz, Daniel (author), Huhn, Florian (author), Gesemann, Sebastian (author), Dierksheide, Uwe (author), van de Meerendonk, R. (author), Manovski, P. (author), Schröder, A. (author)We present results from two large-volume volumetric flow experiments. The first of these, investigating a thermal plume at low velocities (up to 0.35 m/s) demonstrates the abilities and requirements to reach volume sizes up to and probably beyond one cubic meter. It is shown that the use of Helium filled soap bubbles (HFSBs) as tracers, combined...conference paper 2016

Collisions of small and heavy non-spherical particles settling in turbulence are very important for systems such as ice clouds and proto-planetary disks where the particle spectra evolution is strongly dependent on the collision induced growth rate. Still, the influence of the particle shape on the collision probability is virtually unknown....conference paper 2015

The drag reduction effect of a semi-circular riblet-structured surface in a turbulent boundary layer is experimentally investigated using the micro-pillar shear stress sensor MPS3. The MPS3 sensor is a novel tool for the quantitative measurement of the wall-shear stress distribution and possesses a high spatial and temporal resolution. The...conference paper 2015

To investigate small scale turbulent structures and their statistical properties in non-isotropic turbulent flow subjected to favorable and adverse pressure gradients, a novel method to divide the instantaneous flow field into strictly monotonic elements is applied to tomographic particle-image velocimetry data.Especially the scaling regimes of...conference paper 2015

(author)Multiple optical measurement techniques have been applied for the investigation of a propeller-wing wind tunnel model. The (half) wind tunnel model is equipped with a nine bladed propeller and its wing has active Coanda blowing over the whole span of the wing. The aim of the investigation is to gain understanding of the flow phenomena,...conference paper 2013
