SUMMARY:Prof. Dr. Maria Chekhova: Generation of entangled photons in ‘flat’ optics
DESCRIPTION:Bright squeezed vacuum and its applicationsin strong-field physics \n\n\n\n\n\n\n\n \n\n\n\n\n\nMax-Planck-Institut für die Physik des Lichts\, ErlangenStrongly pumped parametric down-conversion produces a state of light that\, on the one hand\, is as intense as laser light\, and on the other hand\, has pronounced quantum features. This state\, known as bright squeezed vacuum\, has zero mean electric field and consists only of quantum fluctuations\, enhanced or suppressed on a subcycle scale. Recently\, we have used this state to drastically modify the dynamics of strong-field effects\, such as non-perturbative harmonics generation and electron ejection from needle tips. \n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\nVenue: RUN auditorium \n\n\n\nHost: GRK 2905\, Rupert Huber

SUMMARY:Dr. Francesco Intravaia: Unpacking Electromagnetic Quantum Fluctuation-Induced Interactions
DESCRIPTION:Humboldt Universität zu BerlinFluctuations are ubiquitous in both classical and quantum realms\, underpinning a wide range of phenomena across physics\, from biophysics and chemistry to gravity and cosmology. In the ongoing race toward miniaturization\, interest in electromagnetic quantum fluctuation-induced interactions has surged—not only for foundational insights but also for technological applications. While many of these interactions are negligible at macroscopic scales\, they become crucial at microscopic scales\, posing both challenges and opportunities for modern quantum technologies. Paradigmatic examples include van der Waals and Casimir interactions\, which can be either advantageous or disruptive in the design of microscopicdevices.The study of these phenomena draws on a highly interdisciplinary background\, merging advances in nonequilibrium physics\, quantum electrodynamics\, atomic physics\, and condensed matter physics. Unpacking electromagnetic quantum fluctuation-induced interactions opens up new perspectives\, deepening our understanding of the underlying physics and paving the way for future advancements in the field. \n\n\n\n \n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\nVenue: RUN auditorium \n\n\n\nHost: GRK 2905\, Rupert Huber
