Qhov kev ua xyem xyav ntawm chav-kub superconductivity uas tau ua rau muaj kev xav hauv lub ntiaj teb kev tshawb fawb hauv zej zog tej zaum yuav yog lwm zaj dab neeg "hma tuaj".
Tom qab ntau lub koom haum tshawb fawb thoob ntiaj teb ua tsis tau rov tsim dua qhov hu ua chav kub kub superconductor LK-99 ua los ntawm cov kws tshawb fawb Kauslim, South Kauslim cov chaw tshawb fawb hauv cheeb tsam tau tshuaj xyuas qhov project thiab thaum kawg xaus lus tias, raws li cov pov thawj uas twb muaj lawm, nws Nws tsis tuaj yeem ua pov thawj tias LK-99 yog chav tsev kub superconductor.
Raws li Yonhap News Agency, "LK-99 Pawg Neeg Tshawb Fawb" tsim los ntawm Kaus Lim Kauslim Lub Koom Haum Saib Xyuas Kev Ncaj Ncees tau hais tias tsis muaj "Meissner effect" raug soj ntsuam hauv cov yeeb yaj kiab thiab cov ntaub ntawv ntsig txog LK-99.
Lub npe hu ua Meissner effect, uas yog, qhov tshwj xeeb "ua tiav diamagnetism" ntawm superconductors. Cov ntaub ntawv zoo ib yam yog nyob rau hauv ib qho chaw sib nqus, thiab cov kab hlau nplaum feem ntau dhau los ntawm lawv, tab sis cov hlau nplaum hauv lub superconductor yeej ib txwm sib npaug rau 0, uas tuaj yeem thaws cov kab sib nqus quab yuam tawm thiab tshem tawm hauv huab cua.

(Yog tias koj tsis nkag siab txog cov nyhuv Meissner, koj tuaj yeem saib qhov kev sim ua haujlwm Meissner los ntawm Mr. Gu Chen, Department of Physics, Tsinghua University hnub no, uas yog qhov xav tau heev)
Pawg neeg pov thawj tau hais rau Yonhap News Agency tias ntxiv rau cov nyhuv Meissner, superconductors tseem yuav nthuav tawm "flux pinning" cov nyhuv thaum hnov mob nrog cov hlau nplaum, uas yog, tus superconductor yuav raug kho ntawm ib qho chaw tshwj xeeb saum cov hlau nplaum.
Cov yeeb yaj kiab levitation ntawm LK-99 nyob deb ntawm qhov sib nqus flux pinning nyhuv. Cov vis dis aus qhia tau tias LK-99 tsis ruaj khov thaum levitating thiab yuav ua rau hauv huab cua. Tsis tas li ntawd, pab pawg tshawb fawb LK-99 kuj tau lees paub hauv ib daim ntawv xa mus rau arXiv tias thaum hnov mob nrog cov hlau nplaum, tsuas yog ib feem ntawm cov qauv tuaj yeem raug tshem tawm hauv huab cua, tsis yog cov qauv ua tiav. Pawg neeg pov thawj ntseeg tau hais tias cov qauv no tsuas yog txav mus deb ntawm cov hlau nplaum vim yog diamagnetism, es tsis ua rau pom cov nyhuv Meissner.
Tsis tas li ntawd, pawg neeg pov thawj tau sau tseg tias cov ntaub ntawv hauv daim ntawv kuj txawv ntawm cov kab hluav taws xob superconductor. Rau cov superconductors, qhov sib nqus susceptibility rov mus rau xoom ntawm qhov kub thiab txias, tab sis LK-99 qhia qhov tsis zoo.
Pawg neeg pov thawj ntseeg tau hais tias daim duab sib nqus hloov pauv hloov pauv ntawm LK-99 tsuas yog qhia cov diamagnetism, thiab ntau cov ntaub ntawv uas tsis yog superconductors kuj muaj diamagnetism.
Cov tswv cuab ntawm pawg neeg pov thawj tau xam phaj hais rau Yonhap Xov Xwm:
"Peb txoj haujlwm tsis tau hloov pauv thiab cov ntaub ntawv tam sim no tsis txaus los ua pov thawj tias LK-99 yog chav tsev kub superconductor."
Nws tsim nyog taw qhia tias qhov kev txheeb xyuas saum toj no tau ua tiav yam tsis muaj kev sib cuag nrog LK-99 cov qauv.
Pawg Neeg Saib Xyuas tau thov kom pab pawg Kaus Lim Kauslim Lub Tsev Haujlwm ntawm Quantum Energy Research muab LK-99 cov qauv, tab sis pab pawg tau hais tias vim tias cov ntaub ntawv xa mus raug tshuaj xyuas, cov qauv tsis tuaj yeem muab rau lub sijhawm, thiab lawv yuav tsum tau tos kom txog thaum kev tshuaj xyuas tiav, uas yuav siv sijhawm 2-4 lub lis piam.
Cov tswv cuab ntawm pawg neeg pov thawj tau xam phaj tau hais tias thaum lawv tuaj yeem kov cov qauv, lawv tsuas yog yuav tsum ntsuas nws qhov kev cuam tshuam sib nqus thiab kev tiv thaiv kom pom tias LK-99 puas muaj cov diamagnetism tiav thiab xoom tsis kam ntawm lub superconductor, thiab qhov tseeb yuav sai sai no yuav tshwm sim.
