Railway infrastructure depreciates over multiple decades (UK transport being still heavily reliant on Victorian decisions). GPUs obsolete in a year or two at best (though I suppose applying pressure to get local power reliability improved for data centers might stick a bit longer in places like the US). 2025-12-31T06:32:33Z https://yabu.me/nevent1qqsdxu9xfqfl7etu8vzjrsf7rn30q6wdldu4cj84wynma7shuplnaggzyqej7gskantcksj2q4dmc6ft2kxfrp9qk52c0xr5dytch38mvlhyqsj5xme In reply to <a href='/nevent1qqsrl3y689pfmq2p3hxewpkqy9ujcch7acmhas3rvud66ce506m35tgd74jav'>nevent1q…4jav</a><br/>_________________________<br/><br/>The&#39;re named after  E.E. Jelley, the original version (1930s) is for dye molecules, when they clump together their light absorption shifts and gets much sharper. The more modern version is more general long range coupling between excited states (giving things like enhanced exciton migration with lower loss, but also possible collective enhancements for processes like fluorescence). 2025-05-10T14:55:57Z https://yabu.me/nevent1qqsvk4gm426zurlsfakldcvzqnynnzfgs90pvwga3nqplzhkelz829czyqej7gskantcksj2q4dmc6ft2kxfrp9qk52c0xr5dytch38mvlhyq7z6jz9 In reply to <a href='/nevent1qqsvn6vn8hfzvlc2hs3vskvx7ykt28axf4faqn6am9v5q7ck28rjv4s5adqeh'>nevent1q…dqeh</a><br/>_________________________<br/><br/>If the coupling is strong enough, this happens at room temperature (cf the exciton-polariton condensates in some wide-gap semiconductors). In terms of applications, anything where you need a quantum enhancement, so some literature speculations about changing reaction yields and branching ratios. But would probably be useful for quantum batteries and sensors, J-aggregate type antics, plus amping up whatever level of quantum-ish behaviour there is in photosynthesis for artificial analogues. 2025-05-10T13:10:03Z
