Abacwaningi e-CRANN (Isikhungo Sokucwaninga ng -自适应纳米结构和纳米器件)，kanye neSikole Se-Physics e-都柏林三一学院，namuhla bamemezele ukuthi izinto kazibuthe ezakhiwe eSikhungweni zibonisa ukushintsha okushesha kakhulu kazibuthe okwake kwaqoshwa。
Ithimba lisebenzise amasistimu e-飞秒eLabhorethri Yocwaningo Lwezithombe e-CRANN ukuze lishintshe bese lishintsha kabusha ukuqondiswa kazibuthe kwempahla yalo ngo-trillionths wesekhondi, ngokushesha okuphindwe kasithupha kunerekhodi langaphambilini, kanye nesivinini esiphindwe kayikhulu kunejubane lewashi ikhompuyutha yomuntu siqu。
Lokhu kutholwa kubonisa amandla ezinto ezibonakalayo esizukulwaneni esisha samakhompyutha asebenzisa amandla ashesha kakhulu namasistimu okugcina idatha。
Abacwaningi bathole isivinini sabo sokushintsha esingakaze sibe khona ku-合金ebizwa nge-MRG, eyaqala ukuhlanganiswa yiqembu ngo-2014 isuka ku-锰，i-钌ne-镓。Ocwaningweni, ithimba lishaye amafilimu amancanyana e-MRG ngokuqhuma kwesibani se-laser ebomvu, eletha ama-megawatts wamandla ngaphansi kwengxenye yesigidi sesekhondi。
Ukudlulisa ukushisa kushintsha umumo kazibuthe we-MRG。Kuthatha ingxenye yeshumi eshesha ngendlela emangalisayo ye-piccosecond ukufeza lolu shintsho lokuqala (1 ps = ingxenye yesigidintathu somzuzwana)。Kodwa, okubaluleke nakakulu, iqembu lithole ukuthi lingashintsha ukuma libuyele emuva ngo-10万亿分wesekhondi kamuva。Lokhu ukushintsha kabusha okusheshayo kokuma kuzibuthe okwake kwabonwa。
Imiphumela yabo ishicilelwe kuleli sonto kujenali ehamba phambili ye-physics, Physical Review Letters。
Ukutholwa kungavula izindlela ezintsha zekhompiyutha entsha kanye nobuchwepheshe bolwazi, uma kubhekwa ukubaluleka kwezinto zikazibuthe kulo mkhakha。Kufihlwe kumishini yethu eminingi kagesi, kanye nasezikhungweni zedatha ezinkulu ezisenhliziyweni ye-inthanethi, izinto ezisetshenziswa kazibuthe ziyafunda futhi zigcine idatha。Ukuqhuma kolwazi lwamanje kukhiqiza idatha eyengeziwe futhi kudla amandla amaningi kunangaphambili。Ukuthola izindlela ezintsha ezonga amandla zokukhohlisa idatha, nezinto ezizohambisana nayo, kuwumsebenzi wocwaningo lomhlaba wonke。
Isihluthulelo sempumelelo yamaqembu kaZiqu-zintathu kwaba yikhono lawo lokufinyelela ukushintsha okushesha kakulu ngaphandle kwanoma iyiphi inkambu kazibuthe。Ukushintshwa kwendabuko kukazibuthe kusebenzisa omunye uzibuthe, oza ngezindleko zakho kokubili amandla nesikhathi。Nge-MRG ukushintsha kwafinyelelwa ngokushaya kokushisa, kusetshenziswa ukusebenzelana okuyingqayizivele kwezinto ezibonakalayo nokukhanya。
Abacwaningi bakazique -zintathu uJean Besbas noKarsten Rode baxoxa ngendlela eyodwa yocwaningo:
" Izinto zikammagnetic ngokwemvelo zinenkumbulo ezingase zisetshenziselwe ukuqonda。Kuze kube manje, ukushintsha usuka kwesinye isimo kazibuthe 'okunengqondo 0，' uye kwesinye 'okunengqondo 1，' bekulambele kakhulu amandla futhi kuhamba kancane。Ucwaningo lwethu lukhuluma ngesivinini ngokubonisa ukuthi singashintsha i-MRG sisuke kwesinye isifunda siye kwesinye ngama-picoseconds angu-0.1 futhi ngokubalulekile ukuthi iswishi yesibili ingalandela kuphela ama-piccoseconds ayi-10 kamuva, ehambisana nemvamisa yokusebenza engu-~ 100 gigaherts - ngokushesha kunanoma yini eke yabonwa ngaphambili。
"Lokhu okutholakele kugqamisa ikhono elikhethekile le-MRG yethu lokuhlanganisa ngempumelelo ukukhanya nokuphotha ukuze sikwazi ukulawula uzibuthe ngokukhhan anya nokukhanya ngozibuthe kuma-timescale angafinyeleleki kuze kube manje "
Ephawula ngomsebenzi wethimba lakhe, uSolwazi Michael Coey，三一物理学院和CRANN，“Ngo-2014 ngesikhathi mina nethimba lami simemezela okokuqala ukuthi sesisungule ingxube entsha ye-锰，i-ruthenium ne-镓，eyaziwa nge-MRG, asikaze basola ukuthi izinto zinalawa mandla amangalisayo we-磁光。
" Lokhu kuboniswa kuzoholela emibonweni emisha yedivayisi esekelwe ekukhanyeni nakukazibuthe okungase kuzuze ekukhuleni kwesivinini esikhulu nokusebenza kahle kwamandla, mhlawumbe ekugcineni kuqaphele idivayisi eyodwa yendawo yonke enenkumbulo ehlanganisiwe nokusebenza okunengqondo。Kuyinselele enkulu, kodwa sibonise ukwaziswa okungenza kwenzeke。Sithemba ukuthi sizothola uxhaso kanye nokusebenzisana kwezimboni ukuze siphishekele umsebenzi wethu "
