What is a photon, really? 😬 A new study applies first quantization to light and bridges classical optics and quantum mechanics. This framework, published in #AdvancedPhotonics, reveals the "quantum diversity" of photons. 🔗 Read the full story here: https://bit.ly/4plHKBd

When a beer garden visit results in you & your colleagues cutting off branches 🌿 to see esculin #fluorescence … Freshly cut chestnut branches leak a milky substance that contains esculin, a colorless compound that fluoresces under UV light. #physics ⚛️ #chemistry #chemsky #science 🧪 #scicomm

Every day is a good day to make red cabbage rainbows 🌈 (the juice contains the pigment anthocyanine, which is an excellent #pH indicator) #science 🧪 #sciencesky #chemsky #scicomm #physics ⚛️

Finally back at it 😍 Fixed all the instruments and restored the signature vaporwave aesthetic of our lab … #physics ⚛️ #sciencesky 🧪 #science #photonics 💡 #scicomm

🧪 lovely #scicomm article- not that I understand it any more than before but it seems that physicists are also confused 😂 www.nature.com/articles/d41...

Only love 💛 for our hollow core fiber (when it still worked … experimental #physics is 10% cool lab work, 90% fixing the laser) #sciencesky #chemsky #science #scicomm #photonics💡 🧪 ⚛️

Behind the scenes of this year’s @munichsoapbox.bsky.social Kids Corner with @e-keil.bsky.social 🧪🥼⚗️ We had so much fun - nothing beats getting other people excited about science😍 #scicomm What’s you favourite science experiment for outreach activities?🤓 - Mine involves red cabbage juice!🧃😌

Baking but make it science with 3D printed cookie cutters #sciencesky #science 🧪 #physics ⚛️

Call for Volunteers‼️ #SoapboxScience Event in #Munich! 🧬🔬🚀 We're looking for #volunteers to support our speakers, help set up the event, engage the audience, and bring energy to the day! 🙌 There will be a pre-event workshop and you'll receive an event T-shirt as a thank-you! 💚 Sign up now! 🎉

Gotta love #chemistry sometimes 😍 #chemiluminescence #sciencesky #womeninstem #science 🧪 #physics ⚛️ #photonics 💡

Our #spectroscopy lab showing its best side 😍 This is one of our hollow-core fiber pump-probe experiments, specifically tailored for blue light excitation. That’s how we look at #carotenoid and #chlorophyll photophysics 🌱 #optics #science 🧪 #sciencesky #physics ⚛️ #photonics 💡 #photosynthesis

Throwback to a cool double rainbow 🌈 over Garching campus. Sometimes #optics loves you back … #science 🧪 #sciencesky #physics ⚛️ 💡

Check out our new publication on ultrafast energy transfer in chlorophyll! 🧪💡

Chocolate science! Preparing some experiments for my end of the year #ChemSky lecture @hhu.bsky.social by imprinting a diffraction grating on tempered #chocolate. Also a great way to explain polymorphism of cocoabutter crystals 🤓🧪🥽

We had ourselves a merry little Xmas party. With a touch of Neon. And Minigolf.

Another day, another opportunity to accidentally create plasma while aligning our hollow-core fiber … #science 🧪 #physics ⚛️ #optics #photonics #sciencecommunication
