The proposed error indicator bounds the error quantities globally in space from above and below, and globally in time from above and locally from below. A space--time adaptive algorithm is proposed using the derived error indicator. Numerical experiments illustrate and complement the theory.}}, author = {{Kovács, Balázs and Lantelme, Michael Frederik Raúl}}, booktitle = {{arXiv:2407.02101}}, title = {{{A posteriori error estimates for parabolic partial differential equations on stationary surfaces}}}, year = {{2024}}, } @article{64270, author = {{Ganguly, Pritam and Krötz, Bernhard and Kuit, Job J.}}, issn = {{0019-3577}}, journal = {{Indagationes Mathematicae}}, number = {{2}}, pages = {{482--496}}, publisher = {{Elsevier BV}}, title = {{{A note on Lp-factorizations of representations}}}, doi = {{10.1016/j.indag.2024.07.002}}, volume = {{36}}, year = {{2024}}, } @article{64550, author = {{Zens, Leon and Besaga, Vira and Möller, Jens and Gerhardt, Nils Christopher and Hofmann, Martin}}, issn = {{1094-4087}}, journal = {{Optics Express}}, publisher = {{Optica Publishing Group}}, title = {{{Holographic measurement of gain and linewidth enhancement factor in semiconductor waveguides}}}, doi = {{10.1364/oe.538741}}, year = {{2024}}, } @article{64585, author = {{Lindemann, Markus and Gerhardt, Nils Christopher and Dainone, Pambiang Abel and Renucci, Pierre and Bouché, Alexandre and Morassi, Martina and Devaux, Xavier and George, Jean-Marie and Jaffrès, Henri and Lemaitre, Aristide and Xu, Bo and Stoffel, Mathieu and Chen, Tongxin and Lombez, Laurent and Lagarde, Delphine and Cong, Guangwei and Ma, Tianyi and Pigeat, Philippe and Vergnat, Michel and Rinnert, Hervé and Marie, Xavier and Han, Xiufeng and Mangin, Stephane and Rojas-Sánchez, Juan-Carlos and Wang, Jian-Ping and Beard, Matthew C. and Žutić, Igor and Figueiredo Prestes, Nicholas and Lu, Yuan}}, journal = {{Nature}}, number = {{8005}}, pages = {{783 -- 788}}, title = {{{Controlling the helicity of light by electrical magnetization switching}}}, doi = {{10.1038/s41586-024-07125-5}}, volume = {{627}}, year = {{2024}}, } @article{64549, author = {{Zens, Leon and Besaga, Vira and Möller, Jens and Gerhardt, Nils Christopher and Hofmann, Martin}}, issn = {{1094-4087}}, journal = {{Optics Express}}, publisher = {{Optica Publishing Group}}, title = {{{Holographic measurement of gain and linewidth enhancement factor in semiconductor waveguides}}}, doi = {{10.1364/oe.538741}}, year = {{2024}}, } @inproceedings{59704, author = {{Kagarura, Geoffrey Mark and Hilleringmann, Ulrich and Petrov, Dmitry}}, booktitle = {{2023 IEEE International Conferences on Internet of Things (iThings) and IEEE Green Computing & Communications (GreenCom) and IEEE Cyber, Physical & Social Computing (CPSCom) and IEEE Smart Data (SmartData) and IEEE Congress on Cybermatics (Cybermatics)}}, publisher = {{IEEE}}, title = {{{A low cost weather monitoring, PV and prediction system in East Africa}}}, doi = {{10.1109/ithings-greencom-cpscom-smartdata-cybermatics60724.2023.00130}}, year = {{2024}}, } @inproceedings{64296, author = {{Lindemann, Markus and Gerhardt, Nils Christopher and Hofmann, Martin R. and Ledentsov, N.

By contrast, robust information storage and magnetic random-access memories are implemented using the spin of the carrier and the associated magnetization in ferromagnets2. The missing link between the respective disciplines of photonics, electronics and spintronics is to modulate the circular polarization of the emitted light, rather than its intensity, by electrically controlled magnetization. Here we demonstrate that this missing link is established at room temperature and zero applied magnetic field in light-emitting diodes2,3,4,5,6,7, through the transfer of angular momentum between photons, electrons and ferromagnets. With spin–orbit torque8,9,10,11, a charge current generates also a spin current to electrically switch the magnetization. This switching determines the spin orientation of injected carriers into semiconductors, in which the transfer of angular momentum from the electron spin to photon controls the circular polarization of the emitted light2. The spin–photon conversion with the nonvolatile control of magnetization opens paths to seamlessly integrate information transfer, processing and storage. Our results provide substantial advances towards electrically controlled ultrafast modulation of circular polarization and spin injection with magnetization dynamics for the next-generation information and communication technology12, including space–light data transfer. The same operating principle in scaled-down structures or using two-dimensional materials will enable transformative opportunities for quantum information processing with spin-controlled single-photon sources, as well as for implementing spin-dependent time-resolved spectroscopies.}}, author = {{Dainone, Pambiang Abel and Prestes, Nicholas Figueiredo and Renucci, Pierre and Bouché, Alexandre and Morassi, Martina and Devaux, Xavier and Lindemann, Markus and George, Jean-Marie and Jaffrès, Henri and Lemaitre, Aristide and Xu, Bo and Stoffel, Mathieu and Chen, Tongxin and Lombez, Laurent and Lagarde, Delphine and Cong, Guangwei and Ma, Tianyi and Pigeat, Philippe and Vergnat, Michel and Rinnert, Hervé and Marie, Xavier and Han, Xiufeng and Mangin, Stephane and Rojas-Sánchez, Juan-Carlos and Wang, Jian-Ping and Beard, Matthew C. and Gerhardt, Nils Christopher and Žutić, Igor and Lu, Yuan}}, issn = {{0028-0836}}, journal = {{Nature}}, keywords = {{Lasers, LEDs and light sources, Spintronics}}, number = {{8005}}, pages = {{783--788}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Controlling the helicity of light by electrical magnetization switching}}}, doi = {{10.1038/s41586-024-07125-5}}, volume = {{627}}, year = {{2024}}, } @inproceedings{64298, author = {{Lindemann, Markus and Gerhardt, Nils Christopher and Hofmann, Martin R. and Ledentsov, N. and Ledentsov, N.
