SUMMARY:Frontiers of Quantum Metrology for New Physics Searches
DESCRIPTION:The Standard Model (SM) of particle physics has demonstrated remarkable predictive and descriptive capabilities across a wide range of phenomena. It has withstood extensive testing through a diverse array of methodologies encompassing various fields within physics. Notwithstanding its impressive track record\, the SM grapples with significant challenges. In fact\, it encounters a fundamental inconsistency with the very existence of our Universe. Specifically\, the Standard Model fails to elucidate the observed disparity between matter and antimatter. Moreover\, all endeavors aimed at unifying gravity with the foundational interactions delineated by the SM have thus far met with limited success. Plentiful observational data on galactic and larger scales cannot be explained based on the observed matter content in the framework of „normal gravity.“ The prevailing view is that invisible „dark matter“ dominates the matter content of the Universe . In addition\, observations indicate that the Universe is expanding at an accelerating rate\, attributing this to „dark energy”. \nThe extraordinary advances in quantum control of matter and light have been transformative for atomic and molecular precision measurements enabling probes of the most basic laws of Nature to gain a fundamental understanding of the physical Universe. Exceptional versatility\, inventiveness\, and rapid development of precision experiments supported by continuous technological advances and improved atomic and molecular theory led to rapid development of many avenues to explore new physics. Precision measurements in atomic\, molecular\, and optical (AMO) physics have lately made significant contributions to the quest for new particles and physics. \nThe main target audience would be composed of students at the master and PhD level. The program entails a series of lectures delivered by renowned experts in the domains of quantum sensors\, quantum optics\, precision metrology\, and fundamental physics. These meticulously crafted lectures are designed to equip the next generation of aspiring researchers with a comprehensive understanding of these dynamic fields. This foundational knowledge will serve as a springboard for their future contributions and accomplishments. This exceptional opportunity empowers emerging scholars to delve deeply into the latest developments and applications within the realm of quantum metrology. It prepares them to take a leading role in shaping the future of quantum research and future theories of physics. \nThe accommodation and all meals during the school will be provided by the Physikzentrum. You will be accommodated directly in the building of the Physikzentrum – the school location. \nConfirmed speakers: \n\nEric Cornell (JILA and University of Colorado)\nElina Fuchs (University of Hannover)\nAndrew Ludlow (University of Colorado and NIST)\nHolger Mueller (UC Berkeley)\nSilke Ospelkaus (University of Hannover)\nIgor Pikovsky (Stockholm University & Stevens Institute of Technology)\nSurjeet Rajendran (Johns Hopkins University)\nPiet Schmidt (PTB Braunschweig)Arne Wickenbrock (University of Mainz)

SUMMARY:Ultimate photonics: one photon\, one molecule - Talk by Prof. Stephan Götzinger from MPI Erlangen
DESCRIPTION:Physikalisches Kolloquium\nSommersemester 2025 \nDienstag 13.05.2025\, 16:45 Uhr \nHörsaal MS 3.1\, Physikzentrum\, Mendelssohnstraße 2/3 \nProf. Dr. Stephan Götzinger\nMax Planck Institute for the Science of Light\, Erlangen\, Germany\nUniversity of Erlangen–Nuremberg\, Erlangen\, Germany \nUltimate photonics:\none photon\, one molecule\nNovel concepts aiming at efficient processing of information require a strong and controlled coupling of single photons with single atomic quantum systems. In this talk\, I will first give an introduction to the efficient generation of single photons using planar dielectric antennas. These antennas allow us to collect the emission from an arbitrarily oriented single quantum emitter with >99% efficiency. By using a planar metallodielectric antenna applied to an organic molecule\, we demonstrate the most regular stream of single photons reported to date. The measured intensity fluctuations were well below the shot-noise limit and amounted to 2.2 dB squeezing. \nIn the second part of the talk\, I will discuss our efforts toward the realization of quantum networks and present experiments where photons and single solid-state emitters strongly interact. A single molecule can amplify a weak laser beam and generate nonlinear effects like three-photon amplification and four-wave mixing. To achieve an even stronger interaction\, we have coupled a single molecule to a tunable Fabry-Perot microcavity. The system is operated in the strong coupling regime of cavity quantum electrodynamics\, where a strong Purcell factor effectively turns the molecule into a twolevel quantum system. We observe 99% extinction of a laser beam\, which means that our molecule in the cavity acts almost as a perfect scatterer of photons. \nCoffee and Cookies before the talk \nInvited by Prof. Dr. Uta Schlickum\, Institut für Angewandte Physik \nTel. 0531 391 8503
