Controlling magnon densities in magnetic materials enables driving spin transport in magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon densities in a thin-film magnetic insulator via microwave excitation of coherent sp

In this paper we model user behaviour in Twitter to capture the emergence of trending topics. For this purpose, we first extensively analyse tweet datasets of several different events. In particular, for these datasets, we construct and investigate t

Optically coherent nitrogen-vacancy centers in ��m-thin etched diamond membranes

Autor: Ruf, Maximilian, IJspeert, Mark, van Dam, Suzanne, de Jong, Nick, Berg, Hans van den, Evers, Guus, Hanson, Ronald

Diamond membrane devices containing optically coherent nitrogen-vacancy (NV) centers are key to enable novel cryogenic experiments such as optical ground-state cooling of hybrid spin-mechanical systems and efficient entanglement distribution in quant
