Nā ʻenehana Quantum: Nā ʻike hou i nā kaʻina hana superconducting

ʻO ka hoʻomohala ʻana i ka lolouila quantum hiki ke hoʻoponopono i nā pilikia, hiki i nā kamepiula kahiko ke hoʻoponopono me ka hoʻoikaika nui a ʻaʻole loa - ʻo ia ka pahuhopu e ʻimi ʻia nei e nā hui noiʻi e ulu mau nei ma ka honua holoʻokoʻa. ʻO ke kumu: Nā hopena quantum, ka mea i hoʻomaka mai ka honua o nā mea liʻiliʻi a me nā hale, hiki ke hoʻohana i nā noi ʻenehana hou. ʻO nā mea i kapa ʻia he superconductors, ka mea e ʻae ai i ka hoʻoponopono ʻana i ka ʻike a me nā hōʻailona e like me nā kānāwai o ka quantum mechanics, i manaʻo ʻia he mau mea hoʻohiki no ka hoʻokō ʻana i nā kamepiula quantum. ʻO kahi kikoʻī o nā nanostructure superconducting, ʻo ia wale nō ka hana ma nā haʻahaʻa haʻahaʻa loa a no laila paʻakikī ke lawe ʻia i nā noi kūpono. googletag.cmd.push(hana() {googletag.display('div-gpt-ad-1449240174198-2′); });

ʻO nā mea noiʻi ma ke Kulanui o Münster a me Forschungszentrum Jülich i kēia manawa, no ka manawa mua, hōʻike i ka mea i ʻike ʻia ʻo ka quantization ikehu i nā nanowires i hana ʻia me nā superconductors kiʻekiʻe-ʻo ia hoʻi nā superconductors, kahi i hoʻokiʻekiʻe ʻia ai ka mahana ma lalo o ka nui o nā hopena mechanical quantum. Manaʻo ka superconducting nanowire i nā mokuʻāina ikehu i koho ʻia i hiki ke hoʻohana ʻia e hoʻopili i ka ʻike. I loko o nā superconductors kiʻekiʻe, ua hiki i nā mea noiʻi ke nānā no ka manawa mua i ka absorption o kahi photon hoʻokahi, kahi māmā māmā e lawelawe ana i ka lawe ʻana i ka ʻike.

"Ma ka ʻaoʻao hoʻokahi, hiki i kā mākou hopena ke kōkua i ka hoʻohana ʻana i ka ʻenehana hoʻoluʻu maʻalahi i nā ʻenehana quantum i ka wā e hiki mai ana, a ma kekahi ʻaoʻao, hāʻawi lākou iā mākou i nā ʻike hou loa i nā kaʻina hana e hoʻokele nei i nā mokuʻāina superconducting a me kā lākou dynamics. ʻaʻole maopopo," wahi a ke alakaʻi noiʻi ʻo Jun. Prof. Carsten Schuck mai ka Institute of Physics ma Münster University. No laila, pili paha nā hopena no ka hoʻomohala ʻana i nā ʻano ʻenehana kamepiula hou. Ua paʻi ʻia ke aʻo ʻana ma ka puke pai Nature Communications.

Ua hoʻohana ka poʻe ʻepekema i nā superconductors i hana ʻia i nā mea yttrium, barium, copper oxide a me ka oxygen, a i ʻole YBCO no ka pōkole, kahi i hana ai lākou i kekahi mau uea lahilahi nanometer. Ke hoʻokō nei kēia mau hale i ka hoʻoikaika kino kino i kapa ʻia ʻo 'phase slips'. Ma ka hihia o YBCO nanowires, fluctuations o ka hoʻopaʻa lawe ukana kumu hoʻololi i ka supercurrent. Ua noiʻi nā mea noiʻi i nā kaʻina hana i loko o nā nanowires i nā mahana ma lalo o 20 Kelvin, e like me ka minus 253 degere Celsius. I ka hui pū ʻana me nā helu hoʻohālike, hōʻike lākou i ka quantization o nā mokuʻāina ikehu i nā nanowires. Ua ʻike ʻia ka mahana i komo ai nā uea i ke kūlana quantum ma 12 a i 13 Kelvin—he wela he mau haneli mau manawa kiʻekiʻe ma mua o ka wela e pono ai no nā mea hana maʻamau. ʻO kēia ka mea i hiki ai i nā ʻepekema ke hana i nā resonator, ʻo ia hoʻi, nā ʻōnaehana oscillating i hoʻopaʻa ʻia i nā alapine kikoʻī, me ka lōʻihi o ke ola ʻana a mālama i nā kūlana mechanical quantum no ka lōʻihi. He koi kēia no ka hoʻomohala lōʻihi o nā kamepiula quantum nui aʻe.

ʻO nā mea koʻikoʻi hou aʻe no ka hoʻomohala ʻana i nā ʻenehana quantum, akā hiki nō hoʻi no nā diagnostics lapaʻau, he mau mea ʻike hiki ke hoʻopaʻa inoa i nā kiʻi hoʻokahi. Ke hana nei ka hui noiʻi a Carsten Schuck ma Münster University no kekahi mau makahiki i ka hoʻomohala ʻana i nā mea ʻike kiʻi hoʻokahi e pili ana i nā superconductors. ʻO ka mea i hana maikaʻi i nā haʻahaʻa haʻahaʻa, ua hoʻāʻo nā ʻepekema a puni ka honua e hoʻokō me nā superconductors kiʻekiʻe no nā makahiki he ʻumi. I nā nanowires YBCO i hoʻohana ʻia no ke aʻo ʻana, ua lanakila kēia hoʻāʻo no ka manawa mua. "ʻO kā mākou mau ʻike hou e hoʻokaʻawale i ke ala no ka wehewehe ʻana i ka manaʻo hoʻokolohua hou a me nā hoʻomohala ʻenehana," wahi a ka mea kākau kumu ʻo Martin Wolff mai ka hui noiʻi Schuck.

Hiki iā ʻoe ke hōʻoia i kā mākou mea hoʻoponopono e nānā pono i kēlā me kēia manaʻo i hoʻouna ʻia a e hana lākou i nā hana kūpono. He mea nui kou mau manaʻo iā mākou.

Hoʻohana wale ʻia kāu leka uila e hōʻike i ka mea nāna i hoʻouna i ka leka uila. ʻAʻole hoʻohana ʻia kāu helu wahi a i ʻole ka helu o ka mea i loaʻa no kekahi kumu ʻē aʻe. E ʻike ʻia ka ʻike āu e hoʻokomo ai ma kāu leka uila a ʻaʻole mālama ʻia e Phys.org ma kekahi ʻano.

E kiʻi i nā mea hou i kēlā me kēia pule a/a i kēlā me kēia lā i kāu pahu pahu. Hiki iā ʻoe ke wehe i ke kau inoa i kēlā me kēia manawa a ʻaʻole mākou e kaʻana like i kāu kikoʻī i nā ʻaoʻao ʻekolu.

Ke hoʻohana nei kēia pūnaewele i nā kuki e kōkua i ka hoʻokele ʻana, e nānā i kāu hoʻohana ʻana i kā mākou lawelawe, a hāʻawi i nā ʻike mai nā ʻaoʻao ʻekolu. Ma ka hoʻohana ʻana i kā mākou pūnaewele, ʻae ʻoe ua heluhelu a hoʻomaopopo ʻoe i kā mākou Kulekele pilikino a me nā ʻōlelo hoʻohana.
