Ngā pātere attosecondhurahia ngā mea ngaro o te whakaroa i te wā
Kua whakakitea e ngā kaipūtaiao i te Hononga o Amerika, me te āwhina o ngā pāoro attosecond, ngā kōrero hou mō tepānga hiko-whakaahuatetukunga hiko-whakaahuaKo te roa o te whakaroa he 700 attoseconds, he roa ake i te mea i whakaarohia i mua. E wero ana tēnei rangahau hou i ngā tauira ariā o nāianei, ā, e whai wāhi ana ki te māramatanga hohonu ake o ngā taunekeneke i waenga i ngā irahiko, e ārahi ana ki te whanaketanga o ngā hangarau pēnei i ngā semiconductors me ngā pūtau solar.
Ko te pānga whakaahua-hiko e pā ana ki te āhuatanga e pā ana ki te whitinga o te mārama ki runga i tētahi ngota, i tētahi ngota rānei i runga i tētahi mata whakarewa, ka taunekeneke te photon ki te ngota, ki te ngota rānei, ka tukuna ngā irahiko. Ehara i te mea ko tētahi o ngā tūāpapa nui o te miihini irahiko anake tēnei pānga, engari he pānga nui anō hoki ki te ahupūngao hou, te matū me te pūtaiao rauemi. Heoi, i roto i tēnei mara, ko te mea e kiia nei ko te wā whakaroa tukunga whakaahua he kaupapa tautohetohe, ā, kua whakamāramahia e ngā tauira ariā maha ki ngā taumata rerekē, engari kāore anō kia kotahi te whakaae.
I te mea kua tino piki ake te ao o te pūtaiao attosecond i ngā tau tata nei, ka tukuna e tēnei taputapu hou tētahi huarahi hou ki te tūhura i te ao moroiti. Mā te ine tika i ngā kaupapa e puta ana i ngā tauine wā poto rawa, ka taea e ngā kairangahau te whiwhi atu i ngā mōhiohio e pā ana ki te whanonga hihiri o ngā matūriki. I roto i te rangahau hou, i whakamahia e rātou he raupapa o ngā pāorooro X-ray kaha-teitei i hangaia e te pūtake mārama honohono i te Stanford Linac Center (SLAC), i roa noa iho i te piriona o te hēkona (attosecond), hei whakakorikori i ngā irahiko matua me te "whana" i waho o te ngota ngota whakahihiri.
Hei tātari atu i ngā ara o ēnei irahiko kua tukuna, i whakamahia e rātou te whakahihiri takitahingā pāorooro taiahohei ine i ngā wā tukunga o ngā irahiko i ngā ahunga rerekē. Nā tēnei tikanga i taea ai e rātou te tatau tika i ngā rerekētanga nui i waenga i ngā wā rerekē i puta mai i te taunekeneke i waenga i ngā irahiko, me te whakaū ka taea e te whakaroa te eke ki te 700 attoseconds. He mea tika kia mōhiotia kāore tēnei kitenga i te whakamana noa i ētahi whakapae o mua, engari ka ara ake anō hoki he pātai hou, me te hiahia kia arotakehia anōtia ngā ariā e tika ana, kia whakahoutia hoki.
Hei tāpiritanga, e whakaatu ana te rangahau i te hiranga o te ine me te whakamārama i ēnei whakaroa wā, he mea nui ki te mārama ki ngā hua o ngā whakamātautau. I roto i te karaihe pūmua, te whakaahua hauora, me ētahi atu tono nui e pā ana ki te taunekeneke o ngā hihi-X me te matū, ka waiho ēnei raraunga hei pūtake nui mō te arotau i ngā tikanga hangarau me te whakapai ake i te kounga whakaahua. Nō reira, kei te whakamahere te tīma ki te haere tonu ki te tūhura i ngā hihiri hiko o ngā momo ngota rerekē kia kitea ai he mōhiohio hou mō te whanonga hiko i roto i ngā pūnaha uaua ake me tō rātou whanaungatanga ki te hanganga ngota, me te whakatakoto i tētahi turanga raraunga pakari ake mō te whanaketanga o ngā hangarau e pā ana i te heke mai.
