Ho sibolloa ha likristale tsa nako e ncha
Mofuta o makatsang oa taba o bitsoang kristale ea nako o sa tsoa hlaha libakeng tse peli tse ncha. Bo-rasaense ba thehile kristale e joalo ka monoammonium phosphate, joalokaha ho tlalehiloe khatisong ea May ea Physical Review Letters, 'me sehlopha se seng se e bōpile ka mokhoa oa mokelikeli o nang le likaroloana tse bōpehileng joaloka linaleli, khatiso ena e hlahile ho Physical Review.
Ho fapana le mehlala e meng e tsebahalang, kristale ea nako ho tloha monoammonium phosphate, e ne e entsoe ka thepa e tiileng e nang le sebopeho sa 'mele se laetsoeng, i.e. kristale ea setso. Lisebelisoa tse ling tseo ho tloha ka nako eo likristale li entsoeng ho fihlela joale li se li sa sebetse. Bo-rasaense ba qalile ho theha likristale tsa nako ka 2016. E 'ngoe ea tsona e ne e entsoe ka daemane e nang le likoli, e' ngoe e entsoe ka ketane ea li-ion tsa ytterbium.
Likristale tse tloaelehileng tse kang letsoai le quartz ke mehlala ea likristale tse tharo-dimensional, tse laetsoeng tsa sebaka. Liathomo tsa tsona li etsa mokhoa o ipheta-phetang o tsejoang ke bo-rasaense ka lilemo tse mashome. Likristale tsa nako li fapane. Nako le nako liathomo tsa tsona li thothomela pele ka nģa e ’ngoe ebe ka lehlakoreng le leng, li hlasimoloha ke matla a khoheli a phophomang (resonance). E bitsoa "letshwao".
Ho ts'oara ka nako ea kristale e fumaneha ka har'a maqhubu a itseng, le hoja maqhubu a sebelisanang a na le li-resonances tse fapaneng. Ka mohlala, liathomo nakong ea likristale tse ithutoang ho e 'ngoe ea liteko tsa selemo se fetileng li ile tsa potoloha ka lebelo la halofo ea maqhubu a matla a khoheli a sebetsang ho tsona.
Bo-rasaense ba re ho utloisisa likristale tsa nako ho ka lebisa ntlafatsong ea lioache tsa athomo, li-gyroscopes le magnetometers, le ho thusa ho theha theknoloji ea quantum. US Defense Advanced Research Projects Agency (DARPA) e phatlalalitse chelete bakeng sa lipatlisiso ho e 'ngoe ea litšibollo tse makatsang tsa mahlale lilemong tsa morao tjena.
- hlooho ea lenaneo la DARPA e bolelletse Gizmodo, Ngaka Roza Alehanda Lukashev. O boletse hore lintlha tsa lithuto tsena ke lekunutu. Motho a ka etsa qeto ea hore ona ke moloko o mocha oa lioache tsa liathomo, tse loketseng haholoanyane le tse tsitsitseng ho feta mehaho e rarahaneng ea laboratori e sebelisoang hona joale. Joalokaha u tseba, li-timers tse joalo li sebelisoa lits'ebetsong tse ngata tsa bohlokoa tsa sesole, ho kenyelletsa, mohlala, GPS.
Mohapi oa Khau ea Nobel Frank Wilczek
Pele likristale tsa nako li fumanoa, li ile tsa emoloa ka khopolo. E qapiloe lilemo tse 'maloa tse fetileng ke Moamerika, mohapi oa Khau ea Nobel. Frank Wilczek. Ka bokhutšoanyane, maikutlo a hae ke ho senya symmetry, joalo ka ha ho le joalo ka liphetoho tsa mekhahlelo. Leha ho le joalo, ka nako ea theory crystals, symmetry e ne e tla robeha eseng feela ka litekanyo tse tharo tsa sebaka, empa hape le ea bone - ka nako. Ho latela khopolo ea Wilczek, likristale tsa nakoana li na le sebopeho se pheta-phetoang eseng sebakeng feela empa le ka nako. Bothata ke hore sena se bolela ho sisinyeha ha liathomo ka lesela la kristale, i.e. motsamao ntle le phepelo ya motlakasese neng se nkoa ke litsebi tsa fisiks e le ntho e ke keng ea etsahala ebile e ke ke ea etsahala.
Le hoja re ntse re e-s'o tsebe likristale tseo setsebi se tummeng se neng se li batla 'me mohlomong ha ho mohla li tla ke li tsebe, ka 2016 litsebi tsa fisiks tsa Univesithi ea Maryland le Univesithi ea Harvard li ile tsa haha likristale tsa nako tse "discontinuous" (kapa discrete). Tsena ke litsamaiso tsa liathomo kapa li-ion tse bonts'ang motsamao o kopaneng le oa cyclic, o itšoere joalo ka boemo bo bocha bo neng bo sa tsejoe, bo hanyetsanang le likhohlano tse nyane.
Le hoja e se ntho e sa tloaelehang joaloka Prof. Wilczek, likristale tse sa tsoa sibolloa tsa nako li khahla ho lekana ho hohela thahasello ea sesole. 'Me e bonahala e le ea bohlokoa ka ho lekaneng.
