Njira yatsopano yowongolera "quantum light"

  Kafukufuku watsopano wochokera ku yunivesite ya Chicago ndi yunivesite ya Shanxi wapeza njira yotsatsira superconductivity pogwiritsa ntchito kuwala kwa laser. Superconductivity imachitika pamene mapepala awiri a graphene amapindika pang'ono pamene akuphatikizidwa pamodzi. Njira yawo yatsopano ingagwiritsidwe ntchito kumvetsetsa bwino momwe zida zimagwirira ntchito ndipo zitha kutsegulira njira zaukadaulo wamtsogolo kapena zamagetsi. Zotsatira za kafukufuku wofunikira zidasindikizidwa posachedwa m'magazini ya Nature.

Zaka zinayi zapitazo, ofufuza ku MIT adapeza modabwitsa: Ngati mapepala okhazikika a maatomu a kaboni apindika pamene ayikidwa, amatha kusinthidwa kukhala ma superconductors. Zida zosowa monga "superconductors" zili ndi kuthekera kwapadera kopereka mphamvu mosalakwitsa. Ma Superconductors ndiwonso maziko a kujambula kwamakono kwa maginito, kotero asayansi ndi mainjiniya amatha kupeza ntchito zambiri kwa iwo. Komabe, ali ndi zovuta zingapo, monga kufuna kuziziritsa pansi pa ziro kuti agwire bwino ntchito. Ofufuzawo amakhulupirira kuti ngati amvetsetsa bwino za sayansi ndi zotsatira zake, amatha kupanga ma superconductors atsopano ndikutsegula mwayi wosiyanasiyana waukadaulo. Chin's lab ndi gulu lofufuza la yunivesite ya Shanxi m'mbuyomu adapanga njira zotsatsira zida zovuta zachulukidwe pogwiritsa ntchito maatomu oziziritsidwa ndi ma lasers kuti zikhale zosavuta kuzisanthula. Pakalipano, akuyembekeza kuchita chimodzimodzi ndi dongosolo lopotoka la bilayer. Chifukwa chake, gulu lofufuza ndi asayansi ochokera ku yunivesite ya Shanxi adapanga njira yatsopano "yofanizira" ma lattice opotoka awa. Ataziziritsa maatomuwo, ankagwiritsa ntchito laser kukonza maatomu a rubidium m’mabwalo aŵiri, ataunjikidwa pamwamba pake. Kenako asayansi adagwiritsa ntchito ma microwave kuti athandizire kulumikizana pakati pa ma lattice awiriwo. Zikuoneka kuti awiriwa amagwirira ntchito limodzi. Tinthu tating'onoting'ono timatha kudutsa muzinthuzo popanda kuchepetsedwa ndi kukangana, chifukwa cha chodabwitsa chotchedwa "superfluidity," chomwe ndi chofanana ndi superconductivity. Kuthekera kwa dongosololi kusintha kupotoza kwa ma lattice awiri kunapangitsa ofufuzawo kuzindikira mtundu watsopano wamadzi ochulukirapo mu maatomu. Ofufuzawo adapeza kuti amatha kuwongolera mphamvu ya ma latiti awiriwa posintha mphamvu ya ma microwave, ndipo amatha kusinthasintha ma latisi awiriwa ndi laser popanda kuyesetsa kwakukulu - ndikupangitsa kuti ikhale yosinthika modabwitsa. Mwachitsanzo, ngati wofufuza akufuna kufufuza kupitirira zigawo ziwiri kapena zitatu kapena zinayi, khwekhwe lomwe tafotokozali limapangitsa kuti kutero kukhale kosavuta. Nthawi iliyonse munthu akapeza superconductor watsopano, dziko lafizikiki limayang'ana mosirira. Koma nthawi ino zotsatira zake zimakhala zosangalatsa kwambiri chifukwa zimatengera zinthu zosavuta komanso zodziwika bwino monga graphene.
