Abacwaningi base-CRNN (Isikhungo Sokucwaninga Nge-Adaptive Nanostructures and Nanodevices), kanye neSikole SePhysics e-Trinity College Dublin, namuhla bamemezele ukuthiimpahla kazibutheithuthukiswe esikhungweni ibonisa ukushintsha kazibuthe okusheshayo okwake kwarekhodwa.
Ithimba lisebenzise amasistimu e-laser e-femtosecond 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 sibonwe ku-alloy ebizwa nge-MRG, eyaqala ukuhlanganiswa yiqembu ngo-2014 isuka ku-manganese, i-ruthenium ne-gallium.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-picosecond ukuze kuzuzwe lolu shintsho lokuqala (1 ps = ingxenye yesigidintathu sesekhondi).Kodwa, okubaluleke nakakhulu, iqembu lithole ukuthi lingashintsha ukuma libuyele emuva ngo-10 trillionths 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 ukubalulekaimpahla kazibuthekule mboni.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 ikhono lawo lokufinyelela ukushintsha okushesha kakhulu ngaphandle kwenkundla kazibuthe.Ukushintshwa kwendabuko kukazibuthe kusebenzisa omunye uzibuthe, oza ngezindleko ngokwamandla akho nesikhathi.Nge-MRG ukushintsha kwafinyelelwa ngokushaya kokushisa, kusetshenziswa ukusebenzelana okuyingqayizivele kwento nokukhanya.
Abacwaningi bakaZiqu-zintathu uJean Besbas noKarsten Rode baxoxa ngendlela eyodwa yocwaningo:
“Izinto zikaZibuthengokwemvelo unenkumbulo engasetshenziselwa 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 ukushintshwa kwesibili kungalandela kuphela ama-piccoseconds ayi-10 kamuva, okuhambisana nemvamisa yokusebenza engu-~ 100 gigahertz—ngokushesha kunanoma yini eke yabonwa ngaphambili.
"Lokhu okutholakele kugqamisa ikhono elikhethekile le-MRG yethu lokuhlanganisa ngempumelelo ukukhanya nokuphotha ukuze sikwazi ukulawula uzibuthe ngokukhanya nokukhanya ngozibuthe kuma-timescale angafinyeleleki kuze kube manje."
Ephawula ngomsebenzi wethimba lakhe, uSolwazi Michael Coey, weTrinity School of Physics and CRANN, uthe, “Ngo-2014 ngesikhathi mina nethimba lami simemezela okokuqala ukuthi sesenze ingxube entsha ye-manganese, i-ruthenium ne-gallium, eyaziwa nge-MRG, asikaze wasola ukuthi into inalawa mandla amangalisayo we-magneto-optical.
“Lokhu kuboniswa kuzoholela emibonweni emisha yedivayisi esekelwe ekukhanyeni nakukazibuthe okungase kuzuze ekwenyukeni kwesivinini esikhulu nokusebenza kahle kwamandla, mhlawumbe ekugcineni kuqhamuke 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.”
