Ucwaningo olusha oluvela eNyuvesi yaseChicago kanye neNyuvesi yaseShanxi luthole indlela yokulingisa i-superconductivity kusetshenziswa ukukhanya kwe-laser. I-Superconductivity kwenzeka lapho amashidi amabili e-graphene esonteka kancane njengoba egqinsiwe ndawonye. Indlela yabo entsha ingase isetshenziselwe ukuqonda kangcono ukuziphatha kwezinto ezibonakalayo futhi ingase ivule indlela yobuchwepheshe be-quantum noma ugesi wesikhathi esizayo. Imiphumela yocwaningo efanelekile isanda kushicilelwa kujenali Imvelo.
Eminyakeni emine edlule, abacwaningi e-MIT bathola into emangalisayo: Uma amashidi avamile ama-athomu ekhabhoni esonteka njengoba enqwabelene, angaguqulwa abe ama-superconductors. Izinto ezingavamile ezifana "nama-superconductors" zinekhono eliyingqayizivele lokudlulisa amandla ngokungenasici. Ama-Superconductors nawo ayisisekelo sokucabanga kwe-magnetic resonance yamanje, ngakho ososayensi nonjiniyela bangathola izinto eziningi ezisetshenziswa kuzo. Kodwa-ke, banokungalungi okumbalwa, njengokudinga ukupholisa ngaphansi kweziro ngokuphelele ukuze kusebenze kahle. Abacwaningi bakholelwa ukuthi uma beyiqonda ngokugcwele i-physics nemiphumela, bangakha ama-superconductors amasha futhi bavule amathuba ahlukahlukene ezobuchwepheshe. Ilebhu kaChin kanye neqembu labacwaningi baseNyuvesi yaseShanxi ngaphambilini basungule izindlela zokuphindaphinda izinto eziyinkimbinkimbi ze-quantum zisebenzisa ama-athomu apholile namalaser ukuze kube lula ukuzihlaziya. Okwamanje, banethemba lokwenza okufanayo ngohlelo olusontekile lwebilayer. Ngakho-ke, ithimba labacwaningi nososayensi abavela eNyuvesi yaseShanxi bathuthukise indlela entsha "yokulingisa" la ma-lattice asontekile. Ngemva kokupholisa ama-athomu, basebenzisa i-laser ukuze bahlele ama-athomu e-rubidium abe ama-lattice amabili, ahlanganiswe phezu kwelinye. Ososayensi babe sebesebenzisa ama-microwave ukuze kube lula ukuxhumana phakathi kwama-lattice amabili. Kuvele ukuthi bobabili basebenzisana kahle. Izinhlayiya zingahamba kokuqukethwe ngaphandle kokuncishiswa ukungqubuzana, ngenxa yento eyaziwa ngokuthi "i-superfluidity," efana ne-superconductivity. Ikhono lesistimu lokushintsha i-twist orientation yama-lattice amabili avumele abacwaningi ukuthi bathole uhlobo olusha lwe-superfluid kuma-athomu. Abacwaningi bathole ukuthi bangakwazi ukushuna amandla okusebenzelana kwama-lattice amabili ngokushintsha ubukhulu bama-microwaves, futhi bakwazi ukuzungezisa ama-lattice amabili ngelaser ngaphandle komzamo omkhulu -- bawenze uhlelo oluguquguqukayo ngendlela emangalisayo. Isibonelo, uma umcwaningi efuna ukuhlola ngale kwezendlalelo ezimbili kuya kwezintathu noma ezine, ukusetha okuchazwe ngenhla kwenza kube lula ukwenza kanjalo. Ngaso sonke isikhathi lapho othile ethola i-superconductor entsha, umhlaba wefiziksi ubheka phezulu ngokutuswa. Kodwa kulokhu umphumela ujabulisa kakhulu ngoba usekelwe ezintweni ezilula nezivamile njenge-graphene.
