SUMMARY:HZDR Data Management Days 2025 - Shaping Research Data Practices with Lasers4EU
DESCRIPTION:This year’s HZDR Data Management Days will take place from Tuesday\, 11 November (1 p.m.) to Wednesday\, 12 November (3 p.m.)\, featuring a mix of lectures and interactive workshops.The programme on 12 November is only for internal participants. \nIn the context of advancing digitalisation and an ever-increasing need for reproducibility\,  this year’s event will focus on the data and software management landscape in general and at HZDR in particular. \nHZDR colleagues will share insights into typical challenges in data and software management and present practical solutions developed in their daily work. \nOn 11 November\, the lectures will be held in a hybrid format and are open to external participants. Lasers4EU partners are warmly invited to join the online sessions. \nA session of particular relevance for the Lasers4EU community will address data management planning using RDMO (Research Data Management Organiser). As funding agencies increasingly require Data Management Plans (DMPs) defining how data and metadata are handled during and after projects\, the HZDR instance of RDMO\, accessible via Helmholtz ID\, supports collaborative preparation of DMPs\, even with external partners. \nWithin this context\, the Lasers4EU project serves as a potential use case for tailoring generic DMP questionnaires to specific needs\, distinguishing between questions for proposing scientists\, access-providing facilities\, and repository providers. The session will therefore be of direct interest to Lasers4EU partners involved in data management\, access coordination\, and research infrastructure development. \nFor more information and the full programme\, please visit HZDR Data Management Days 2025 \n			\n				Register here

SUMMARY:Laserlab-Europe Talk: Nonlinear optical diode effect in a magnetic Weyl semimetal\, 26 Nov 2025
DESCRIPTION:Speaker: Christian Tzschaschel (University of Zurich) \nWeyl semimetals have emerged as a promising quantum material system to discover novel electrical and optical phenomena\, due to their combination of nontrivial quantum geometry and strong symmetry breaking. Here\, I will present the observation of the nonlinear optical diode effect (NODE) in the magnetic Weyl semimetal CeAlSi\, where the magnetic state of CeAlSi introduces a pronounced directionality in the nonlinear optical second-harmonic generation (SHG). By physically reversing the beam path\, we show that the measured SHG intensity can change by at least a factor of six between forward and backward propagation over a wide bandwidth exceeding 250 meV. Supported by density-functional theory calculations\, we establish the linearly dispersive bands emerging from Weyl nodes as the origin of the extreme bandwidth. By utilizing the electronically conductive semimetallic nature of CeAlSi\, we demonstrate current-induced magnetization switching and thus electrical control of the NODE in a mesoscopic spintronic device structure. Our results advance ongoing research to identify novel nonlinear optical/transport phenomena in magnetic topological materials. The NODE further opens new pathways for the unidirectional manipulation of light such as electrically controlled optical isolators [1]. \n[1] CT et al.\, Nature Communications 15\, 3017 (2024) \n			\n				Watch the Talk
