Quantum Electrodynamics Kev qhuab qhia lub ntsej muag
Quantum electrodynamics yog cov ceg ntev tshaj thiab tshaj plaws hauv kev txhim kho ntawm qhov kev tshawb nrhiav quantum teb, luv li QED. Nws feem ntau yog kawm cov txheej txheem yooj yim ntawm kev sib cuam tshuam ntawm hluav taws xob teb thiab kev hais plaub. Hauv paus ntsiab lus, nws cov ntsiab lus sau luv luv ntawm cov hluav taws xob sib xyaw cov txheej txheem hauv ntau hom teb ntawm atomic physics, molecular physics, solid physics, nuclear physics, thiab particle physics. Nws kawm txog cov khoom ntawm cov xov hluav taws xob ntawm kev sib txuas ntawm electromagnetic (piv txwv li, kev tshaj tawm thiab nqus cov duab ntawm photons), tiam thiab kev rhuav tshem ntawm cov khoom ntim (xws li qhov zoo thiab tsis zoo ntawm cov hluav taws xob), thiab cov tawg ntawm cov ntawv foob, thiab cov tawg ntawm cov pov thawj thiab cov duab. Cov. Los ntawm cov kev xam pom ntawm ntau daim ntawv thov ntau yam, yooj yim thiab meej cov kev xav ua tiav, thiab qhov tseeb siab nyob rau hauv kev ua raws nrog kev sim, nws yog qhov muaj txiaj ntsig hauv kev niaj hnub physics.
