Einige Neuerungen vorab: Die Kolloquien des Instituts für Angewandte Physik finden ab diesem Semester dienstags von 16:00 bis 17:00 Uhr statt (statt wie bisher um 17:15 Uhr). Veranstaltungsort ist nun die Handbibliothek (S217, Raum 134) – ein Raum, der nicht nur zentral liegt, sondern hoffentlich auch zu angeregtem wissenschaftlichen Austausch beiträgt. Wie im vergangenen Semester wird es wieder zwei Reihen geben: * das Kolloquium für Angewandte Physik * das Kolloquium Quantentechnologien Welches Kolloquium jeweils stattfindet, ergibt sich wie gehabt aus der eingeladenen Person bzw. dem Thema. Für Ihre Planung: Wenn Sie einen Termin reservieren möchten, schreiben Sie mir bitte eine kurze Nachricht – idealerweise mit dem Titel des Vortrags und der entsprechenden Kolloquiumsreihe. Ich wünsche Ihnen schöne Beiträge und ein anregendes Programm. Für internationale Kolleg:innen: Please find the updated colloquium schedule for the summer semester.

So far these gases have been produced using time-sequential cooling stages and after creation they unfortunately decay through unavoidable loss processes. This limits what can be done with them. For example it becomes impossible to extract a continuous-wave atom laser, which has promising applications for precision measurement through atom interferometry [1]. I will present how we achieve continuous Bose-Einstein condensation and create condensates (BECs) that persist in a steady-state for as long as we desire. Atom loss is compensated by feeding fresh atoms from a continuously replenished thermal source into the BEC by Bose-stimulated gain [2]. We are now using our new techniques also to tackle another challenge: the creation of continuously operating optical atomic clocks, which promise higher measurement bandwidth and better short term stability than traditional optical clocks that operate in a pulsed manner [3,4,5,6]. I will present our progress in building superradiant and zero-deadtime clocks. *References* 1. N. P. Robins, P. A. Altin, J. E. Debs, and J. D.

April 2025_*_ __LUH__, Building 3406, Room 317, Callinstr. 36, 30167 Hannover _ *_15:30-17:00_*Colloquium by *Baptist Piest *SYRTE, Observatoire de Paris, France Title: *Implementation of Delta-Kick squeezing in an atom interferometer* Abstract: Atom interferometers are versatile devices to detect accelerations or rotations with high sensitivity and accuracy with important applications in geodesy, navigation and fundamental physics. The phase readout of light-pulse atom interferometers with classical input states is naturally limited by the quantum projection noise leading to the standard quantum limit. In this case, the sensitivity to accelerations is given by 1/(kT²Sqrt(N)) with the scale factor kT² and the atom number N. Increasing the sensitivity of atom interferometers is one of the main challenges in the field. Conducting experiments in long baseline facilities or microgravity can considerably increase the sensitivity. A different approach to further improve the performance of atom interferometers is given by circumventing the standard quantum limit using entangled states. This has successfully been demonstrated in recent experiments by the groups of J. Thomson [1] and C. Klempt [2]. These experiments made use of strong cavity-atom coupling in a high-finesse cavity and spin-collisions in a dipole trap, respectively. In our experiment we strive to implement and analyze the recently proposed technique of Delta-Kick squeezing [3] and demonstrate an entanglement-enhanced gravimeter operating below shot noise. The entanglement is generated by the non-linear interatomic interactions of a focused Bose-Einstein condensate (BEC) of Rb-87 atoms which leads to momentum squeezing. The experiment is operated at LTE and has previously been used to investigate Casimir-Polder forces between Rb-87 atoms and a polished surface [4]. Since then, it is being prepared for the implementation of Delta-Kick squeezing. In this talk, I will discuss the experimental setup, the planned implementation of the entanglement-enhanced interferometer and show our recent progress. [1] G. Greve et al.

April um 16:15 findet ein Sonder-Kolloquiums-Vortrag statt, digital per Zoom. Offizielle Ankündigung, Titel und Abstract, Zoom-Link kommen noch. Sprecherin wird Dr. Tina Ebert (Lawrence Livermore National Laboratory) sein. Wie einige von Euch bereits informiert sind, gibt es Überlegungen, dass Frau Ebert einen Antrag stellt für eine BMBF-Nachwuchsgruppe im Programm "Fusionstalente", siehe https://www.bmbf.de/SharedDocs/Bekanntmachungen/DE/2024/03/2024-03-07-Bekan… Deshalb soll sich Frau Ebert mit Ihrem Vortrag bei uns vorstellen. Ich hänge das CV von Frau Ebert an, Hinweis hierzu: seit März hat sie eine permanente Position am LLNL. Es wäre schön, wenn viele von uns dabei sein können und an der Diskussion teilnehmen. Nach dem Vortrag können wir uns kurz intern über die Eindrücke austauschen. Die Info zum Termin bitte ich auch in den Fachgebieten zu verteilen. Herzlichen Dank, Thomas PS: Ich bitte, die kurzfristige Aktion zu entschuldigen. Dies ist dem engen Zeitplan wg. BMBF-Deadline sowie den sehr aktuellen Entwicklungen zum Thema "Kernfusion" in Hessen geschuldet. -- Prof. Dr. Thomas Halfmann Institut für Angewandte Physik Technische Universität Darmstadt Hochschulstraße 6 64289 Darmstadt (Germany) phone 49-6151-1620740 fax 49-6151-1620327 mobile 49-177-4005810 thomas.halfmann(a)physik.tu-darmstadt.de http://www.iap.tu-darmstadt.de/nlq

In the meantime, you may wish to take a look at the submission to the 2026 update of the European Strategy for Particle Physics, prepared on behalf of the TVLBAI Proto-Collaboration, which appeared on the arXiv this morning: http://arxiv.org/abs/2503.21366 We are looking forward to welcoming you to Hannover soon! Best regards, The Workshop Organisers %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% *Workshop Poster:* ** *https://indico.cern.ch/event/1522217/page/38059-workshop-poster* *Workshop Scope:* The 3rd TVLBAI workshop follows the formation of the TVLBAI Proto-Collaboration and will focus on discussing the technology and physics drivers for large-scale Atom Interferometry as well as establishing a comprehensive roadmap. The primary objectives are to bring together researchers from diverse institutions, foster strategic discussions, and develop a pathway towards funding for Terrestrial Very-Long Baseline Atom Interferometer projects expected to become operational in the mid-2030s. *_International Organisation Committee:_* Gianluigi Arduini, CERN, Geneva, Switzerland Kai Bongs, DLR Institute for Quantum Technologies, Germany Philippe Bouyer, University of Amsterdam, Netherlands Diego Blas, Institut de Física d'Altes Energies, Spain Oliver Buchmueller, Imperial College London, UK Sergio Calatroni, CERN, Geneva, Switzerland Benjamin Canuel, CNRS, Institut d'Optique Graduate School, France Marilù Chiofalo, University of Pisa and INFN Pisa, Italy Fabio Di Pumpo, University of Ulm, Germany Michael Doser, CERN, Geneva, Switzerland John Ellis, King's College London, UK Naceur Gaaloul, Leibniz University Hannover, Germany Jason Hogan, Stanford University, US Peter Knight, Imperial College London, UK Timothy Kovachy, Northwestern University, US Ernst Rasel, Leibniz University Hannover, Germany Ulrich Schneider, University of Cambridge, UK Guglielmo Tino, University of Florence and LENS, Italy Wolf von Klitzing, IESL-FORTH, Greece Mingsheng Zhan, Wuhan Institute of Physics and Mathematics, China *_Local Organisation Committee:_* Elina Fuchs, Leibniz University Hannover, Germany Naceur Gaaloul, Leibniz University Hannover, Germany Klemens Hammerer, Leibniz University Hannover, Germany Michèle Heurs, Leibniz University Hannover, Germany Jürgen Müller, Leibniz University Hannover, Germany Maria Alessandra Papa, Leibniz University Hannover, Germany Ernst Maria Rasel, Leibniz University Hannover, Germany Dennis Schlippert, Leibniz University Hannover, Germany Michael Werner, Leibniz University Hannover, Germany -- ========================= Prof. Oliver Buchmueller Royal Society Leverhulme Trust Senior Research Fellow ------------------------- Imperial College London South Kensington Campus Prince Consort Rd, London SW7 2BW tel: +44 (0)207-594-7792 mobile:+44 (0)7788 526563 fax: +44 (0)207-823-8830 -------------------------- European Organization for Nuclear Research (CERN) CH- 1211 Geneva 23 Switzerland Office: 510-1-017 tele: (+41 22) 767 7520 fax: (+41 22) 766 8759 ==========================
