Abacwaningi e-CRANN (Isikhungo Socwaningo Ngezakhiwo Ze-Nano Eziguquguqukayo kanye Nezisetshenziswa Ze-Nano), kanye neSikole Sefiziksi eTrinity College Dublin, namuhla bamemezele ukuthiizinto ezisebenza ngogesiokwakhiwa eSikhungweni kubonisa ukushintshashintsha okushesha kakhulu kukagesi okuke kwaqoshwa.
Ithimba lisebenzise izinhlelo ze-laser ze-femtosecond e-Photonics Research Laboratory e-CRANN ukushintsha bese kushintsha kabusha ukuqondiswa kukazibuthe kwezinto zabo ngama-trillionths omzuzwana, ngokushesha okuphindwe kasithupha kunerekhodi langaphambilini, kanye ngokushesha okuphindwe kayikhulu kunejubane lewashi lekhompyutha yomuntu siqu.
Lokhu kutholwa kubonisa amandla ale nto esizukulwaneni esisha samakhompyutha ashesha kakhulu kanye nezinhlelo zokugcina idatha ezisebenzisa amandla kahle.
Abacwaningi bafinyelele isivinini sabo sokushintsha esingakaze sibonwe ngaphambili ku-alloy ebizwa ngokuthi i-MRG, eyaqala ukwenziwa yiqembu ngo-2014 kusuka ku-manganese, i-ruthenium kanye ne-gallium. Kulolu cwaningo, ithimba lifinyelele amafilimu amancane e-MRG ngokukhanya okubomvu kwe-laser, okuletha ama-megawatts amandla ngaphansi kwengxenye eyodwa kweziyizigidigidi zomzuzwana.
Ukudluliselwa kokushisa kushintsha ukuma kwe-magnetic kwe-MRG. Kuthatha ishumi le-picosecond elisheshayo ngendlela engenakucatshangwa ukuze kufezwe lolu shintsho lokuqala (1 ps = i-trillionth eyodwa yomzuzwana). Kodwa, okubaluleke kakhulu, ithimba lithole ukuthi lingashintsha ukuma futhi ama-trillionth ayi-10 yomzuzwana kamuva. Lokhu ukushintsha kabusha okusheshayo kakhulu kokuma kwe-magnet okwake kwabonwa.
Imiphumela yabo ishicilelwe kuleli sonto kumagazini ohamba phambili wefiziksi, i-Physical Review Letters.
Lokhu kutholwa kungavula izindlela ezintsha zobuchwepheshe bekhompyutha kanye nolwazi olusha, uma kubhekwa ukubalulekaizinto ezisebenza ngogesis kulo mkhakha. Ezifihliwe kumadivayisi ethu amaningi kagesi, kanye nasezikhungweni zedatha ezinkulu enhliziyweni ye-inthanethi, izinto ezisebenzisa amandla kazibuthe zifunda futhi zigcine idatha. Ukuqhuma kolwazi kwamanje kukhiqiza idatha eningi futhi kudla amandla amaningi kunanini ngaphambili. Ukuthola izindlela ezintsha ezisebenzisa amandla ngendlela eyongayo zokulawula idatha, kanye nezinto ezifanelana, kuyinto ekhathazayo ocwaningweni lomhlaba wonke.
Isihluthulelo sempumelelo yamaqembu eTrinity kwakuwukukwazi kwawo ukufeza ukushintsha okusheshayo ngaphandle kwensimu yamagnetic. Ukushintsha kwendabuko kwamagnet kusebenzisa enye imagnet, ebiza kakhulu ngokwamandla nesikhathi. Nge-MRG ukushintsha kwafezwa ngokushaya kokushisa, kusetshenziswa ukusebenzisana okuyingqayizivele kwezinto nokukhanya.
Abacwaningi beTrinity uJean Besbas noKarsten Rode baxoxa ngenye indlela yocwaningo:
"Izinto ezisebenza ngogesingokwemvelo banememori engasetshenziswa kwi-logic. Kuze kube manje, ukushintsha kusuka kwesinye isimo sikagesi 'u-logical 0,' uye kwesinye 'u-logical 1,' kuye kwaba yinto edla amandla kakhulu futhi ehamba kancane kakhulu. Ucwaningo lwethu lubhekana nesivinini ngokubonisa ukuthi singashintsha i-MRG kusuka kwesinye isimo siye kwesinye kuma-picosecond angu-0.1 futhi okubaluleke kakhulu ukuthi ukushintsha kwesibili kungalandela ama-picosecond ayi-10 kuphela kamuva, okuhambisana nemvamisa yokusebenza engu-~ 100 gigahertz—ngokushesha kunanoma yini ebonwe ngaphambili.
"Lokhu okutholiwe kugqamisa ikhono elikhethekile le-MRG yethu lokuhlanganisa ukukhanya nokujikeleza ngempumelelo ukuze sikwazi ukulawula amandla kazibuthe ngokukhanya kanye nokukhanya okunamandla kazibuthe ezilinganisweni zesikhathi ezingafinyeleleki kuze kube manje."
Ephawula ngomsebenzi weqembu lakhe, uSolwazi uMichael Coey, iSikole seFiziksi sikaTrinity kanye ne-CRANN, uthe, “Ngo-2014 lapho mina nethimba lami simemezela okokuqala ukuthi sesidale i-alloy entsha ngokuphelele ye-manganese, i-ruthenium kanye ne-gallium, eyaziwa ngokuthi i-MRG, asikaze sisole ukuthi le nto inalo leli khono elimangalisayo le-magneto-optical.
"Lo mboniso uzoholela emibonweni emisha yedivayisi esekelwe ekukhanyeni kanye ne-magnetism engazuza ekukhuleni okukhulu kwesivinini kanye nokusebenza kahle kwamandla, mhlawumbe ekugcineni kufezwe idivayisi eyodwa yendawo yonke enenkumbulo ehlanganisiwe kanye nokusebenza kwe-logic. Kuyinselele enkulu, kodwa sibonise izinto ezingenza kube nokwenzeka. Sithemba ukuthola uxhaso kanye nokubambisana kwemboni ukuze siqhubeke nomsebenzi wethu."
