- Hōʻike ke kumu hoʻohālike e pili pono ana ke kahua magnetic o ka mālamalama i ka hopena Faraday.
- ʻO ka hāʻawi helu ʻia a hiki i ~17% i ka mālamalama ʻike ʻia a hiki i 70% i ka infrared no TGG.
- Hoʻokumu ʻia ka haʻawina ma ka Landau-Lifshitz-Gilbert equation a paʻi ʻia ma Hōʻike Pūnaewele.
- Hiki i nā noi: nā optics kiʻekiʻe, spintronics a me nā ʻenehana quantum ma ʻEulopa.
ʻO ka noiʻi ʻana i ka pilina ma waena o ka mālamalama a me ka mea i hoʻohui ʻia i kahi ʻāpana i manaʻo ʻole ʻia: ka mānoanoa o ka mālamalama Hāʻawi pū ia i ka hopena Faraday.ʻaʻole wale kāna mea uila, e like me kahi noiʻi i pūlima ʻia e kahi hui mai ke Kulanui Hebera o Ierusalema.
Nā hopena, Paʻi ʻia ma Nowemapa 20, 2025 i ka kope Hōʻike PūnaeweleKākoʻo lākou i kēia me kahi kumu hoʻohālike theoretical kēlā Hiki i ka māmā ke hoʻohua i ka torque magnetic i nā meaka helu ʻana i kāna kuleana me nā helu koʻikoʻi: ma kahi o 17% o ka hoʻololi ʻana i ka laulā ʻike ʻia y a hiki i 70% i ka infrared.
He aha nā loli i kā mākou ʻike i ka hopena Faraday?
Durante aneane elua keneturi Ua manaʻo ʻia ʻo ka hoʻololi ʻana o ka mokulele o ka polarization i ka wā e hele ai i kahi mea magnetized i hele maiʻO ka mea nui, mai ka pilina ma waena o ke kahua uila o ka malamalama a me nā uku o ka mea.
El Hoʻopaʻapaʻa ka hana hou ʻaʻole passive ka ʻāpana magnetic o ke kahua electromagnetic: hoʻoulu a ʻūhā māneki kūloko i waena, e like me ke kahua hoʻopalekana waho mau, a ʻAʻole i koe kona hopena ma lalo o kekahi mau kūlana spectral.
ʻO ke ʻano hana a me ke kumu hoʻohālike
ʻO ka hui, alakaʻi ʻia e Amir Capua a me Benjamin Assouline, hoʻohana i ka Landau-Lifshitz-Gilbert equation e wehewehe i ka dynamics o nā wili electron i loko o nā mea magnetic i hoʻopaʻa ʻia i ka hana a ke kahua magnetic o ka mālamalama.
Hōʻike ka papa hana pehea Hoʻopili ka ʻāpana magnetic oscillating i nā wili a hoʻohana i kahi torque hiki ke anaI kā lākou hōʻoia ʻana, ua koho nā mea kākau i kahi aniani kuhikuhi i ka magneto-optics: ka gallium-terbium garnet (TGG), hoʻohana nui ʻia e aʻo a calibrate i ka hopena Faraday.
Nā hualoaʻa nui ma TGG
Ke hoʻohana nei i ke kumu hoʻohālike i ka TGG, ʻo ka haʻawina magnetic o ka mālamalama e wehewehe e pili ana i hoʻokahi 17% o ka hoʻololi polarization i ka spectrum i ʻike ʻia a hiki ke piʻi i ka 70% i ka infrared, ka nui e koi ai i ka loiloi o nā wehewehe maʻamau.
ʻO ke kaumaha pili o kēlā me kēia haʻawina e pili ana i ka kōā nalu a me nā waiwai optical a me ka magnetic o ka mea, e hōʻike ana i ka laulā hoʻolālā no ka hoʻonui ʻana nā mea hana magneto-optical i nā pūʻulu like ʻole.
Nā hopena no nā optics, spintronics a me nā ʻenehana quantum ma ʻEulopa
Ma nā optics i noi ʻia, kahi mana manaʻo o hoʻomāmā māmā E ʻae ia i ka hoʻoponopono ʻana o nā mea hoʻokaʻawale optical, nā modulators Faraday, a me nā mea ʻike kahua me nā hoʻolālā hou e pili ana i ka spectral engineering.
I ka spintronics, e hoʻohana ana i ka ʻāpana magnetic o ke kukui e hoʻokele i ka wili ʻike hana Hiki iā ia ke hoʻomaʻamaʻa i nā hoʻomanaʻo ʻoi aku ka maikaʻi a me nā ʻōnaehana hoʻololi ultra-wikiwiki me ka ʻole o ka hoʻopili uila.
No nā ʻenehana quantum, ʻo ka hoʻohui ʻana o ka māmā-magnetism e kuhikuhi i nā ala no ka hoʻopunipuni qubits pili wili, me ka hoihoi no nā kaiaola ʻEulopa e kālele ana i nā photonics i hoʻohui ʻia a me ka hoʻomalu like ʻana o nā mokuʻāina magnetic.
ʻO nā mea i koe e hōʻoiaʻiʻoʻia
ʻOiai ʻo ka hōʻike i hōʻike ʻia he theoretical, hōʻike ka hana i kahi hoʻolālā hoʻokolohua plausible: kiʻekiʻe sensitive magneto-optical metrology, rigorous spectral calibration, a me ka hoʻohana nā kumu kukui paʻa loa e hoʻokaʻawale maopopo i ka hāʻawi magnetic mai ka uila.
Hiki i nā ʻōnaehana photonics ʻEulopa a me nā hale hana kulanui ke hoʻoponopono i kēia hōʻoia hoʻokolohuae hoʻonui ana i ka nānā ʻana i nā mea magneto-optical ʻē aʻe, me nā alakaʻi nalu a me nā resonator.
Nā nīnau nui o ka haʻawina
ʻO wai ka mea hōʻailona ma ka hana? He hui mai ka Ke Kulanui Hebera o Ierusalema, me Amir Capua a me Benjamin Assouline ma ke alakai.
Ma hea i hoʻolaha ʻia ai? I loko o ka puke puke puka wehe Hōʻike Pūnaewele, ka mea e maʻalahi ai ka ka nānā ʻana a me ka hana hou ʻana e nā hui ʻē aʻe.
He aha ka mea i kālailai ʻia? ʻO ke aniani TGG, kahi kuhikuhi i nā haʻawina o ka hopena Faraday ma muli o kāna pane magneto-optical kiʻekiʻe.
No ke aha ia mea? No ka mea, hōʻike ʻo ia i ka mālamalama, ma waho aʻe o kāna hana uila, he a hoʻopā pololei a hiki ke helu ʻia ma ke kumuhana, me ka hopena i ka hoʻolālā ʻana o ka mea hana.
Hoʻohui ka manaʻo i kahi papa o ka pololei i ka hoʻomaopopo ʻana o hopena FaradayHoʻohui ia i ke kuleana o ke kahua magnetic o ka mālamalama me nā helu a me kahi ʻano kumu kumu paʻa, a wehe i kahi ala kūpono e hoʻohana ai i kēia hāʻawi i nā noi photonic a me quantum i makemake nui i ka noiʻi ʻEulopa a me ka lole ʻenehana.
He kanaka ʻenehana wau i hoʻololi i kāna mau makemake "geek" i ʻoihana. Ua hoʻohana au ma mua o 10 mau makahiki o koʻu ola me ka hoʻohana ʻana i ka ʻenehana ʻokiʻoki a me ka hoʻomaʻamaʻa ʻana i nā ʻano papahana āpau ma muli o ka ʻike maʻemaʻe. I kēia manawa ua loea wau i ka ʻenehana kamepiula a me nā pāʻani wikiō. ʻO kēia no ka mea ʻoi aku ma mua o 5 mau makahiki aʻu i kākau ai no nā pūnaewele like ʻole e pili ana i ka ʻenehana a me nā pāʻani wikiō, e hana ana i nā ʻatikala e ʻimi nei e hāʻawi iā ʻoe i ka ʻike āu e pono ai ma kahi ʻōlelo i hoʻomaopopo ʻia e nā mea a pau.
Inā he mau nīnau kāu, pili koʻu ʻike mai nā mea a pau e pili ana i ka ʻōnaehana hana Windows a me Android no nā kelepona paʻalima. A ʻo kaʻu hoʻohiki ʻana iā ʻoe, makemake mau wau e hoʻolilo i mau minuke a kōkua iā ʻoe e hoʻoholo i nā nīnau āu e loaʻa ai ma kēia ao pūnaewele.
