I-athikili echaza imiphumela yocwaningo yanyatheliswa kumagazini Ukubuyekezwa Kwemvelo B Izincwadi. I-Polariton iyizinhlayiyana ze-quantum ezibandakanya i-Photon ne-Exciton. Ngenxa ye-duet eyingqayizivele yokukhanya nendaba, i-polariton ivule amathuba abanzi wokwakha isizukulwane esisha samadivayisi asuselwa ku-polariton.
Abaphenyi be-Faculty of Applematics kanye ne-physics ye-University of Cambridge Alexander Johston kanye Kirill Kalinin kanye noProfesa Wezikhungo zeSyoltech kanye neCambridge of Complariton ehlobene namadivayisi we-semiconductor ayakwazi lingisa ama-molecule anezakhiwo ezahlukahlukene.
I-molecule ejwayelekile iqoqo lama-athomu ahambisana nokuhleleka okuthile. Ngokwezakhiwo zayo ezibonakalayo ze-molecule, ngokwesibonelo, i-H2O yamanzi i-molecule yamanzi, yehluka kakhulu kuma-athomu afakiwe ekwakhiweni kwawo, kulokhu, ama-athomu we-hydrogen nomoya-mpilo. "Emsebenzini wethu, sibonisa ukuthi amaqoqo wokuxhumana polariton kanye ne-condensate ye-Photonic angakha inani lezinhlaka ezihlukile nezihluke ngokuphelele -" ama-molecule ", ukuthonya ongakwenza. Lezi "ama-molecule okufakelwa" futhi ama-condensanes afakiwe ekwakhiweni kwawo anezinto ezihlukile zamandla, izakhiwo ze-optical kanye nezindlela zokubona, "kusho u-Alexander Johnston.
Enqubweni yokumodelwa kwezinombolo kwama-polariton amabili, ama-polariton amathathu none asebenzayo, abacwaningi badonsela ukunaka ekubakhona kwezindawo ezijwayelekile ze-asymmetric. Ngasikhathi sinye, kwabanye kuphela ama-condensanen abenobunzima obufanayo esimweni esiyinhloko. "Ngesikhathi sokucwaninga okwengeziwe, sathola ukuthi izifundazwe ezinjalo zingathatha izindlela ezahlukahlukene ezingalawulwa ngokulungisa amapharamitha ngamunye ngokomzimba wohlelo. Ngokusekelwe kulokhu okubonile, senze umcabango ngokuba khona "kwe-polariton molecule" futhi wacela ukuphenya amathuba okusetshenziswa kwawo ngohlelo lwemininingwane ye-quantum, "kuyaqhubeka u-Alexander Johnston.
Ikakhulu, abacwaningi babheka lokho okubizwa ngokuthi "i-asymmetric diaward" okubandakanya ama-condensanes amabili axhumana nenombolo engalingani kwezinhlayiya, naphezu kweqiniso lokuthi bawela inani elifanayo lokukhanya. Lapho kuhlanganisa okufayo okubili, kwakhiwa incwadi yezincwadi, okufana nomqondo othile nge-molecule ye-homo-tenor, isibonelo, i-hydrogen molecule H2. Ngaphezu kwalokho, ama-molekyuli e-polariton afashini angakha izakhiwo eziyinkimbinkimbi ezingabhekwa njenge- "polariton compounds".
"Asiboni izithiyo ekwakheni izakhiwo eziyinkimbinkimbi. Ngakho-ke, isifundo sethu senze ukuba sikwazi ukubona ukuba khona kobubanzi bezifundazwe ezihlukene ze-asymmetric ekucushweni kwe-airymmetric, kwathi kwezinye izakhiwo, wonke ama-condensates anezinkinga ezihlukile zazo zonke izivumelwano), okwenza kube khona U-anemibono ngamakhemikhali amakhemikhali, "engeza u-Alexander Johnston.
Uma, ekwakhiweni kwezincwadi ezihlukile, i-diay ye-asymmetric ehlukile kubhekwa njenge- "spin" ehlukile, enqunywe ukuqondiswa kwe-asymmetry yenkululeko yenkululeko (kuzofakwa amapharamitha asemzimbeni ezizimele adingekayo ukuthola izifundazwe): I-Discrete "Backs" izovela ngenxa yokutholakala kwe- "SPINS" I-Cound degree ngaphezu kwamazinga aqhubekayo wenkululeko, anqunywe yizigaba ze-condensate.
Ungalawula ukuqondiswa kwesihlobo ngasinye se-diads ngokuhluka ngamandla wobudlelwano phakathi kwabo. Njengoba ukusetshenziswa kohlelo oluthile oluqhubekayo oluqhubekayo - oluqhubekayo lungathuthukisa ukunemba nokusebenza kahle kohlelo lolwazi lwe-quantum, abacwaningi bahlongoza ukusebenzisa isakhiwo se-hybrid patebook njengesisekelo.
"Ngaphezu kwalokho, sathola izifunda ezahlukahlukene ze-asymmetric zisezinhlelo ezinhlelweni zezincwadi. Ukuqinisekisa ukuguqulwa okubushelelezi kusuka kwesinye isimo kuya kwesinye, kwanele ukumane uguqule amandla we-laser lapho uthola ama-condensates.
Njengoba kunikezwe ubukhona bendawo enjalo, kungacatshangelwa ukuthi lezi zinto zingaba yisisekelo sohlelo olunengqondo olungenalo alusebenzi nge-zero futhi linye njengezibalo zakudala, kepha uhla olubanzi lwezifundazwe. Ngosizo lwe-logic enjalo, amadivaysi e-polariton angenziwa ngezinga eliphansi kakhulu lamandla ahlangene ngokuqhathaniswa nezindlela zendabuko, futhi asebenze ama-oda ambalwa ngobukhulu ngokushesha, "kusho uProfesa uNatalia Berloff.
