Nkhani yofotokoza zotsatira za phunziroli linafalitsidwa m'magazini yamagazini. Polaton ndi tinthu tating'onoting'ono kopangidwa ndi Photon ndi Pretuton. Chifukwa cha nyumba zapadera za kuwala ndi nkhani, polaton imatsegulira chiyembekezo chodzapanga m'badwo watsopano wa zida za Polariton.
Ofufuzawo a luso la masamu ndi ziphunzitso za yunivesite ya Cambridge Abston ndi Pures Kalinin ndi Pulofesa wa Polalten ndi zida za Semiton zomwe zimapezeka mu semitoctor sinthani mamolekyulu okhala ndi zida zosiyanasiyana.
Molekyu mwachizolowezi ndi ma atomu omwe amakhudzana ndi dongosolo linalake. Malinga ndi mawonekedwe ake mwamwano, mwachitsanzo, molekyulu yamadzi ya H2o, imasiyana kwambiri kuchokera ku maatomu omwe akuphatikizidwa, pamenepa, ma atomu a haidrogen ndi okosijeni. "Timalangizo athu, timawonetsa kuti madera olumikizana polaton ndi zithunzi za protonct zitha kupanga zinthu zobisika komanso zosiyana kwathunthu -" mamolekyulu ", kuti mudzipatse zomwe mungachite. "Mamolekyulu oyenda" ndi zogwirizana ndi zomwe zimaphatikizidwa m'mayiko awo zimakhala ndi zigawo zosiyanasiyana, zowoneka bwino ndi zotupa za mawu osston.
Mukukonzekera kuchuluka kwa polaton ya polaton yolumikizirana, ofufuza amafotokoza za kukhalapo kwa mayiko achilendo a asymmetric. Nthawi yomweyo, ena mwa omwe amagwirizana anali ndi vuto lofanana ndi lalikulu. "Popita patsogolo kwambiri, tinapeza kuti mayiko otere amatha kupanga mitundu yosiyanasiyana yomwe imatha kulamulidwa ndi kusintha magawo a dongosolo. Kutengera ndi zomwe adawona, adadzifunsa za mamolekyu a "mamolekyu a Polariton" ndikudzipereka kuti afufuze zomwe amagwiritsa ntchito.
Makamaka, ofufuzawo adawona kuti "asymmetric muakaya" wopangidwa ndi mabatani awiri omwe amalumikizana ndi zigawo zambiri, ngakhale kuti amaziwalitsa kuchuluka komweko. Pophatikiza awiri amwalira, kapangidwe kake kabuokbook kumapangidwa, kofanana ndi molekyu ya Homo-tenor, mwachitsanzo, hydrogen Moleky H2. Kuphatikiza apo, mamolekyu a Polariton amatha kukhala ndi zida zovuta kwambiri zomwe zitha kuonedwa ngati "mankhwala opanga polariton".
"Sitikuwona zopinga zilizonse kuti tilenge zomangira zovuta. Chifukwa chake, kuphunzira kwathu kudapangitsa kuti pakhale kupezeka kwa mitundu yosiyanasiyana ya asymmetric kumayiko osokoneza bongo, ndipo m'magulu ena, zomwe zimapangitsa kuti zikhale ndi mphamvu zosiyanasiyana), zomwe zimapangitsa kuti zitheke onjezerani fanizo ndi mankhwala a Alexander Johston.
Ngati, mu kalembedwe kake kabuku, kalembedwe kake konse kamaganiziridwa ngati kosiyana, ndikutanthauza kusintha kwa kachulukidwe kake ka madigiri Kuyamwa "kumbuyo" kumawonekera chifukwa cha kupezeka kwa "spins" ufulu kuwonjezera pa madigiri opitilira muyeso, omwe amatsimikiziridwa ndi magawo a Conceate.
Mutha kuwongolera kufikiridwa kwa maaaadi aliyense mwa mitundu yosiyanasiyana ya ubale pakati pawo. Popeza kugwiritsa ntchito njira yothandizana ndi kosakanikirana kopitilira muyeso kumatha kukonza zolondola ndi momwe ofufuzawo amafunira kuti agwiritse ntchito zolemba za hybrid monga maziko.
"Kuphatikiza apo, tinapeza mitundu yosiyanasiyana ya asymmetric m'magawo a Triad ndi Mabuku. Kuonetsetsa kusintha kosalala kuchokera ku boma lina kupita kwina, ndikokwanira kungosintha mphamvu ya laser mukamagwirizana.
Popeza analipo kukhalapo kwa malo oterewa, kumatha kuganiza kuti mayiko awa akhoza kukhala maziko a chomveka polariton omwe samagwiritsa ntchito zero ndi amodzi monga momwe mungawerengere. Mothandizidwa ndi mfundo zomveka zoterezi, polariton zitha kupangidwa ndi kuchuluka kwamphamvu kwamphamvu poyerekeza ndi njira zachikhalidwe, ndikugwira ntchito zingapo za kukula mwachangu, "adatero Pulofesa Natalia Berloff.
