Through carrier recombination, the angular momentum of the spin-polarized carriers is transferred to photons, thus leading to the circularly polarized emitted light. The intuition for the operation of such spin-lasers can be obtained from simple bucket and harmonic oscillator models, elucidating their steady-state and dynamic response, respectively. These lasers extend the functionalities of spintronic devices and exceed the performance of conventional (spin-unpolarized) lasers, including an order of magnitude faster modulation frequency. Surprisingly, this ultrafast operation relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both viewed as detrimental in spintronics and conventional lasers. Spin-lasers provide a platform to test novel concepts in spin devices and offer progress connected to the advances in more traditional areas of spintronics."}],"status":"public","publisher":"Elsevier BV","date_updated":"2025-04-25T07:28:46Z","volume":"316-317","date_created":"2025-04-25T07:11:46Z","author":[{"first_name":"Igor","full_name":"Žutić, Igor","last_name":"Žutić"},{"full_name":"Xu, Gaofeng","last_name":"Xu","first_name":"Gaofeng"},{"last_name":"Lindemann","full_name":"Lindemann, Markus","first_name":"Markus"},{"first_name":"Paulo E.","full_name":"Faria Junior, Paulo E.","last_name":"Faria Junior"},{"first_name":"Jeongsu","full_name":"Lee, Jeongsu","last_name":"Lee"},{"full_name":"Labinac, Velimir","last_name":"Labinac","first_name":"Velimir"},{"full_name":"Stojšić, Kristian","last_name":"Stojšić","first_name":"Kristian"},{"last_name":"Sipahi","full_name":"Sipahi, Guilherme M.","first_name":"Guilherme M."},{"first_name":"Martin R.","full_name":"Hofmann, Martin R.","last_name":"Hofmann"},{"orcid":"0009-0002-5538-231X","last_name":"Gerhardt","id":"115298","full_name":"Gerhardt, Nils Christopher","first_name":"Nils Christopher"}],"title":"Spin-lasers: spintronics beyond magnetoresistance","doi":"10.1016/j.ssc.2020.113949","publication_identifier":{"issn":["0038-1098"]},"publication_status":"published","year":"2020","citation":{"apa":"Žutić, I., Xu, G., Lindemann, M., Faria Junior, P.

If firms use team tournaments to increase energy-efficient behavior and thus employee performance, they may face unintended consequences, like a bifurcation effect: Individuals drop out if they believe that they cannot win the contest. By contrast, high-performing employees may overexert themselves. Additionally, some individuals might be tempted to free-ride. In a field experiment with truck drivers, we analyze whether proportional sharing of the bonus within teams based on individual effort instead of egalitarian sharing reduces both bifurcation and free-riding during team tournaments. Our results reveal that (1) the team contest improves performance; (2) this increase in performance is overall slightly stronger under the proportional than under the egalitarian sharing rule, using ceteris paribus comparisons; and (3) the performance increase is mainly driven by the team member performing worse. </jats:p>","lang":"eng"}],"status":"public","publication":"Organization &amp; Environment","type":"journal_article","language":[{"iso":"eng"}],"_id":"63781","department":[{"_id":"178"},{"_id":"184"}],"user_id":"72497"},{"_id":"64276","user_id":"52730","language":[{"iso":"eng"}],"publication":"Geometric and Functional Analysis","type":"journal_article","status":"public","date_updated":"2026-02-19T13:28:26Z","publisher":"Springer Science and Business Media LLC","volume":30,"author":[{"first_name":"Bernhard","last_name":"Krötz","full_name":"Krötz, Bernhard"},{"last_name":"Kuit","full_name":"Kuit, Job J.","first_name":"Job J."},{"first_name":"Eric M.","last_name":"Opdam","full_name":"Opdam, Eric M."},{"last_name":"Schlichtkrull","full_name":"Schlichtkrull, Henrik","first_name":"Henrik"}],"date_created":"2026-02-19T13:28:12Z","title":"The Infinitesimal Characters of Discrete Series for Real Spherical Spaces","doi":"10.1007/s00039-020-00540-6","publication_identifier":{"issn":["1016-443X","1420-8970"]},"publication_status":"published","issue":"3","year":"2020","intvolume":"        30","page":"804-857","citation":{"ieee":"B.

In the proposed concept, a modular multi-level converter (MMC) is used to step-down the three-phase medium voltage of 10 kV, and provide up to 1 MW of pure DC power to the load consisting of electrolyzers for hydrogen generation. Therefore, each module is extended by an LLC resonant converter to adapt to the specific electrolyzers DC voltage range of 142...220 V and to provide galvanic isolation. In order to achieve a high efficiency for a wide range of load conditions, the input voltage of the LLC converter is adjusted between 600 V and 770 V while operating at resonance or close to resonance. The parameters of the 11kW LLC resonant converter with an integrated leakage inductance are systematically optimized to maximize the efficiency for all loads while achieving zero-voltage switching. For a fast estimation of eddy current losses, a new method is proposed, which uses a single FEM simulation to fit newly developed loss equations. The calculated average efficiency is 97.8%. The prototype of the LLC converter reaches a peak efficiency of over 98% at resonance at half load which is similar to the precalculated value.","lang":"eng"}],"department":[{"_id":"52"}],"user_id":"34289","_id":"29880","language":[{"iso":"eng"}],"keyword":["Full-bridge","High voltage power converters","LLC resonant converter","Multilevel converters","ZVS Converters"],"publication_identifier":{"unknown":["978-1-7281-7160-9"]},"quality_controlled":"1","publication_status":"published","citation":{"short":"R.
