Izixhobo ezincinci kunye neeleser ezisebenzayo ngakumbi

Izixhobo ezincinci kwaye zisebenza kakuhle ngakumbiiileyiza
Abaphandi beRensselaer Polytechnic Institute benze i-isixhobo selaserOko kububanzi beenwele zomntu kuphela, okuya kunceda iingcali zefiziksi zifunde iimpawu ezisisiseko zezinto kunye nokukhanya. Umsebenzi wazo, opapashwe kwiijenali zesayensi ezidumileyo, unokunceda ekuphuhliseni iilaser ezisebenzayo ngakumbi zokusetyenziswa kumacandelo aqala kumayeza ukuya kumveliso.

Iilezaisixhobo senziwe ngezinto ezikhethekileyo ezibizwa ngokuba yi-photonic topological insulator. Ii-photonic topological insulators ziyakwazi ukukhokela ii-photons (amaza kunye namasuntswana enza ukukhanya) ngokusebenzisa iindawo ezikhethekileyo ngaphakathi kwezinto, ngelixa zithintela ezi suntswana ukuba zingasasazeki kwizinto ngokwazo. Ngenxa yesi sizathu, ii-topological insulators zivumela ii-photons ezininzi ukuba zisebenze kunye zizonke. Ezi zixhobo zingasetyenziswa njenge-topological "quantum simulators," ezivumela abaphandi ukuba bafunde i-quantum phenomena - imithetho yendalo elawula izinto ezincinci kakhulu - kwii-mini-labs.
“Ii-photonic topologicalIsigqubuthelo esasenzayo sikhethekile. Sisebenza kubushushu begumbi. Olu luphuculo olukhulu. Ngaphambili, izifundo ezinjalo bezinokwenziwa kuphela kusetyenziswa izixhobo ezinkulu nezibizayo ukupholisa izinto kwi-vacuum. IiLABS ezininzi zophando azinalo olu hlobo lwezixhobo, ngoko ke isixhobo sethu senza abantu abaninzi bakwazi ukwenza olu hlobo lophando lwefiziksi olusisiseko kwilebhu, “utshilo uprofesa oncedisayo weRensselaer Polytechnic Institute (RPI) kwiSebe leSayensi yeZinto kunye noBunjineli kunye nombhali ophezulu wolu phononongo. Olu phononongo belunomlinganiselo omncinci wesampulu, kodwa iziphumo zibonisa ukuba iyeza elitsha libonakalise ukusebenza kakuhle ekunyangeni esi sifo singaqhelekanga semfuza. Silangazelela ukuqinisekisa ezi ziphumo kwizilingo zeklinikhi ezizayo kwaye sinokukhokelela kwiindlela ezintsha zonyango kwizigulane ezinesi sifo.” Nangona ubungakanani besampulu yophando bebuncinci, iziphumo zibonisa ukuba eli yeza litsha libonakalise ukusebenza kakuhle ekunyangeni esi sifo singaqhelekanga semfuza. Silangazelela ukuqinisekisa ezi ziphumo kwizilingo zeklinikhi ezizayo kwaye sinokukhokelela kwiindlela ezintsha zonyango kwizigulane ezinesi sifo.”
“Eli linyathelo elikhulu ekuphuhlisweni kwee-laser kuba umda wesixhobo sethu sobushushu begumbi (ubungakanani bamandla afunekayo ukuze sisebenze) uphantsi ngokuphindwe kasixhenxe kunezixhobo zangaphambili ze-cryogenic,” bongeze njalo abaphandi. Abaphandi beRensselaer Polytechnic Institute basebenzise indlela efanayo esetyenziswa lishishini le-semiconductor ukwenza ii-microchips ukwenza isixhobo sabo esitsha, esibandakanya ukuqokelela iintlobo ezahlukeneyo zezinto umaleko ngomaleko, ukusuka kwinqanaba le-athomu ukuya kwinqanaba le-molecular, ukwenza izakhiwo ezifanelekileyo ezineempawu ezithile.
Ukwenzaisixhobo se-laser, abaphandi bakhulisa iipleyiti ezibhityileyo kakhulu ze-selenide halide (ikristale eyenziwe yi-cesium, i-lead kunye ne-chlorine) baza bakrola iipolymers ezineepateni kuzo. Badibanise ezi plates zekristale kunye neepolymers phakathi kwezinto ezahlukeneyo ze-oxide, nto leyo eyabangela ukuba into ibe nobukhulu obumalunga nee-microns ezi-2 kunye ne-100 microns ubude nobubanzi (ububanzi obuqhelekileyo beenwele zomntu yi-100 microns).
Xa abaphandi babekhanyisa i-laser kwisixhobo se-laser, kwavela ipateni yonxantathu ekhanyayo kwi-interface yoyilo lwezinto. Ipateni imiselwa luyilo lwesixhobo kwaye sisiphumo seempawu ze-topological ze-laser. “Ukukwazi ukufunda i-quantum phenomena kubushushu begumbi lithemba elinomdla. Umsebenzi kaNjingalwazi uBao onobuchule ubonisa ukuba ubunjineli bezinto bunokusinceda siphendule eminye yemibuzo emikhulu kwisayensi.” Utshilo umphathi wobunjineli weRensselaer Polytechnic Institute.
