Kev kawm tshiab los ntawm University of Chicago thiab Shanxi University tau nrhiav ib txoj hauv kev los simulate superconductivity siv laser lub teeb. Superconductivity tshwm sim thaum ob daim duab ntawm graphene yog me ntsis ntswj raws li lawv tau rho tawm ua ke. Lawv cov txheej txheem tshiab yuav siv tau kom nkag siab zoo dua cov cwj pwm ntawm cov ntaub ntawv thiab tuaj yeem qhib txoj kev rau kev ua kom zoo rau yav tom ntej lossis hluav taws xob. Cov kev tshawb fawb txog kev tshawb fawb tau nyuam qhuav luam tawm hauv phau ntawv sau zaj nkauj.

Plaub xyoos dhau los, cov kws tshawb nrhiav ntawm cov kws tshawb fawb tau pom tias muaj cov qauv ntawm cov roj ntsha li qub Cov ntaub ntawv tsis tshua muaj xws li "superconductors" muaj lub peev xwm tshwj xeeb los hloov lub zog flawlessly. Superconductors kuj yog lub hauv paus ntawm kev ua lag luam tam sim no, yog li cov kws tshawb fawb thiab engineers tuaj yeem pom ntau yam siv rau lawv. Txawm li cas los xij, lawv muaj ntau yam tsis zoo, xws li xav kom txias hauv qab no kom yog. Cov kws tshawb nrhiav ntseeg tias yog lawv nkag siab txog lub cev thiab kev cuam tshuam, lawv tuaj yeem tsim kho cov superconductors thiab qhib ntau yam kev ua haujlwm. Chin lub lab thiab cov pab pawg Shanxi University tau tsim cov khoom uas siv cov khoom siv txias atoms thiab lasers kom lawv yooj yim los soj ntsuam. Nyob rau hauv lub sijhawm, lawv vam tias yuav ua tib yam nrog lub kaw lus bilayer. Yog li, pab pawg tshawb fawb thiab cov kws tshawb fawb los ntawm Shanxi University tau tsim txoj kev tshiab rau "simulate" no cov kev ntsuas lattices. Tom qab txias lub atoms, lawv tau siv ib laser los npaj lub chewidium atoms ua ob yam lattices, stacked rau saum ib leeg. Cov kws tshawb fawb cov kws tshawb fawb ces siv microwaves los pab txhawb kev sib cuam tshuam ntawm ob txoj kev ntsuas. Nws hloov tawm tias ob txoj haujlwm ua ke. Hais kom txav mus los ntawm cov khoom uas tsis tau qeeb los ntawm kev sib txhuam, ua tsaug rau qhov tshwm sim, "uas yog zoo ib yam li superconductivity. Lub kaw lus lub peev xwm los hloov lub ntsej muag sib tw ntawm ob txoj lattices tso cai cov kws tshawb nrhiav kom paub txog kev hloov tshiab superfluid hauv atoms. Cov kws tshawb nrhiav pom tias lawv muaj peev xwm kho lub zog ntawm ob txoj kev sib txuam nrog lub microwaves nrog laser tsis muaj kev siv nyiaj ntau dua - ua rau nws lub siab hloov kho. Piv txwv li, yog tus kws tshawb fawb xav tshawb txog ntawm ob mus rau peb lossis txawm tias plaub txheej, teeb tsa piav saum toj no ua rau nws yooj yim ua. Txhua zaus ib tug neeg tshawb pom tus tshiab superconductor, lub cev ntiaj teb ntsia zoo li kev qhuas. Tab sis lub sijhawm no qhov tshwm sim yog txaus siab tshwj xeeb vim tias nws yog raws li cov khoom siv uas yooj yim thiab nquag ua graphene.
