Karolo ea makenete ea leseli e hlalosa hape phello ea Faraday

Lipatlisiso mabapi le tšebelisano lipakeng tsa leseli le lintho li ekelitse karolo e sa lebelloang: the matla a khoheli a khanya E boetse e kenya letsoho ho phello ea Faraday.eseng feela karolo ea eona ea motlakase, ho latela thuto e saennoe ke sehlopha se tsoang Univesithing ea Seheberu ea Jerusalema.

Liphetho, E phatlalalitsoe ka la 20 Pulungoana 2025 ka har'a makasine Litlaleho tsa SaenseBa tšehetsa sena ka mohlala oa theoretical hore Leseli le ka hlahisa torque ea makenete ka thepaho lekanya karolo ea eona ka lipalo tsa bohlokoa: hoo e ka bang 17% ea ho potoloha sebakeng se bonahalang y ho fihla ho 70% ho infrared.

Ke liphetoho life ponong ea rōna ka phello ea Faraday?

Nakong ea lilemo tse ka bang makholo a mabeli Ho ne ho nahanoa hore ho potoloha ha sefofane sa polarization ha ho feta har'a mochine o nang le makenete ho tsoaHa e le hantle, ho tloha tšebelisanong pakeng tsa sebaka sa motlakase sa khanya le litefiso tsa thepa.

El Mosebetsi o mocha o pheha khang ea hore karolo ea makenete ea lebala la motlakase ha e etse letho:e susumetsa a ka hare makenete torque mahareng, ka mokhoa o ts'oanang le matla a khoheli a kantle a kamehla, le phello ea eona ha se mesaletsa tlasa maemo a itseng a spectral.

Methodology le mohlala oa theory

Sehlopha, se etelletsoeng pele ke Amir Capua le Benjamin Assouline, se sebelisa sehlopha sa Landau-Lifshitz-Gilbert equation ho hlalosa matla a li-spins tsa elektronike ka thepa ea makenete e tlas'a ketso ea matla a khoheli a khanya.

Tlhahiso e bontša kamoo The oscillating magnetic component e kopanya ho spins mme e fana ka torque e lekanyangHa ba netefatsa, bangoli ba khethile kristale ea referense ho magneto-optics: the gallium-terbium garnet (TGG), e sebelisoang haholo ho ithuta le ho lekanya phello ea Faraday.

Liphetho tse ngata ho TGG

Ho sebelisa mohlala ho TGG, monehelo oa makenete oa leseli o hlalosa ka e le 'ngoe 17% ea potoloho ea polarization ka ponahalo e bonahalang 'me e ka nyolohela ho 70% ho infrared, boholo bo qobellang ho hlahlojoa ha litlhaloso tse tloaelehileng.

Boima bo lekanyelitsoeng ba monehelo ka mong bo itšetlehile ka boka ba bokahohle le thepa ea optical le makenete ea thepa, e fana ka maikutlo a boholo ba moralo bakeng sa ntlafatso lisebelisoa tsa magneto-optical ka lihlopha tse fapaneng.

Litlamorao ho theknoloji ea optics, spintronics le quantum Europe

Ho optics e sebelisitsoeng, taolo ea ka boomo ea makenete e bakoang ke khanya E ne e tla lumella phetoho ea li-isolators tsa optical, li-modulators tsa Faraday, le li-sensor tsa masimong tse nang le maano a macha a ipapisitseng le boenjiniere ba pono.

Ho li-spintronics, ho sebelisa karolo ea khoheli ho tsamaisa ts'ebetso ea tlhahisoleseling ea spin E ka nolofatsa mehopolo e sebetsang haholoanyane le maano a ho switjha ka potlako ntle le ho kopana le motlakase.

Bakeng sa mahlale a quantum, khokahano ea mabone-magnetism e supa litsela tsa ho qhekella spin-based qubits, ka thahasello bakeng sa tikoloho ea Europe e tsepamisitseng maikutlo ho li-photonics tse kopantsoeng le taolo e tsitsitseng ea linaha tsa makenete.

Se setseng se tlameha ho netefatsoa

Le hoja bopaki bo hlahisitsoeng e le ba khopolo-taba, mosebetsi ona o fana ka moralo o utloahalang oa liteko: metrology ea magneto-optical e hlokolosi haholo, tekano e matla ea spectral calibration, le tšebeliso ea mehloli ea khanya e tsitsitseng haholo ho arola ka mokhoa o sa tsitsang monehelo oa makenete ho tsoa ho motlakase.

Meaho ea mahlale a Europe le lilaboratori tsa univesithi li ka sebetsana le sena netefatso ya ditekoHo eketsa tlhahlobo ho lisebelisoa tse ling tsa magneto-optical, ho kenyelletsa le li-waveguide tse kopaneng le li-resonator.

Lipotso tsa bohlokoa thutong

Ke mang ea saenang mosebetsi oo? Sehlopha se tsoang ho Univesithi ea Seheberu ea Jerusalema, Amir Capua le Benjamin Assouline ba etella pele.

E hatisoa hokae? Ka har'a koranta ea phihlello e bulehileng Litlaleho tsa Saensee leng se thusang ho tekolo le botjha ka lihlopha tse ling.

Ke boitsebiso bofe bo hlahlobiloeng? TGG kristale, sesupo lithutong tsa phello ea Faraday ka lebaka la eona karabo e phahameng ea magneto-optical.

Ke hobane'ng ha e le taba? Hobane e bontša hore leseli, ntle le ts'ebetso ea motlakase, le na le tšusumetso e tobileng ea makenete le quantifiable mabapi le taba, e nang le tšusumetso moralong oa sesebelisoa.

Tlhahiso e eketsa lera la ho nepahala kutloisisong ea Phello ea FaradayE kopanya karolo ea matla a khoheli a khanya le lipalo le moralo o tiileng oa theory, mme e bula mokhoa o sebetsang oa ho sebelisa tlatsetso ena lits'ebetsong tsa photonic le quantum tse khahlang haholo lipatlisiso tsa Europe le lesela la indasteri.
