Ua lawe nā kānaka ʻepekema i kahi ʻanuʻu i ka hoʻokumu ʻana i nā mea hana ikaika e hoʻohana anamakeneka hoʻopiʻi ma ka hana ʻana i ke kope ʻekolu-dimensional mua loa o kahi mea i ʻike ʻia he spin-ice.
He mea ʻokoʻa loa nā mea hau wili no ka mea he mau kīnā ko lākou e hana ana e like me ke kia hoʻokahi o ka magnet.
ʻAʻole kēia mau mākēneki pou hoʻokahi, i ʻike ʻia hoʻi he monopoles magnetic, i loko o ke ʻano; ke ʻoki ʻia kēlā me kēia mea magnetic i ʻelua, e hana mau ia i kahi magnet hou me kahi pou ʻākau a me ke kūkulu hema.
No nā makahiki he ʻumi, ua ʻimi nā kānaka ʻepekema i nā wahi āpau no nā hōʻike o nā mea kūlohelohemakeneka nā monopoles me ka manaʻolana e hoʻohui hope i nā mana kumu o ke kūlohelohe i loko o kahi mea i kapa ʻia ʻo ke kumumanaʻo o nā mea āpau, e kau ana i nā physics āpau ma lalo o hoʻokahi hale.
Eia nō naʻe, i nā makahiki i hala iho nei, ua hiki i nā physicists ke hana i nā mana hana o kahi monopole magnetic ma o ka hoʻokumu ʻana i nā mea wili-hau ʻelua-dimensional.
A hiki i kēia lā, ua hōʻike pono kēia mau hale i kahi monopole magnetic, akā ʻaʻole hiki ke loaʻa ka physics like ke kaupalena ʻia ka mea i hoʻokahi mokulele. ʻOiaʻiʻo, ʻo ia ke geometry ʻekolu-dimensional kikoʻī o ka lattice spin-ice ke kī i kona hiki ke hana i nā hale liʻiliʻi e hoʻohālike.makenekanā monopole.
Ma kahi noiʻi hou i paʻi ʻia i kēia lā ma Nature Communications, ua hana kahi hui i alakaʻi ʻia e nā kānaka ʻepekema ma ke Kulanui ʻo Cardiff i ke kope 3D mua loa o kahi mea wili-hau me ka hoʻohana ʻana i kahi ʻano paʻi a me ka hana ʻana o 3D.
Ua ʻōlelo ka hui ua ʻae ka ʻenehana paʻi 3D iā lākou e hoʻopilikino i ke ʻano o ka hau milo artificial, ʻo ia hoʻi hiki iā lākou ke kaohi i ke ʻano o ka hoʻokumu ʻia ʻana o nā monopoles magnetic a me ka neʻe ʻana a puni i loko o nā ʻōnaehana.
ʻO ka hiki ke hoʻopunipuni i nā magnet mini monopole ma 3D hiki ke wehe i kahi lehulehu o nā noi a lākou e ʻōlelo nei, mai ka hoʻonui ʻana i ka mālama ʻana i nā kamepiula a hiki i ka hoʻokumu ʻana o nā pūnaewele helu 3D e hoʻohālike i ke ʻano neural o ka lolo kanaka.
"No nā makahiki he 10 a ʻoi, ua hana a aʻo nā kānaka ʻepekema i ka hau wili artificial i ʻelua ana. Ma ka hoʻonui ʻana i ia mau ʻōnaehana i ʻekolu ana, loaʻa iā mākou kahi hōʻike pololei loa o ka physics monopole spin-ice a hiki ke aʻo i ka hopena o nā ʻili," wahi a ke alakaʻi kākau ʻo Kauka Sam Ladak mai ke Kula o Physics a me Astronomy o ke Kulanui ʻo Cardiff.
"ʻO kēia ka manawa mua i hiki ai i kekahi ke hana i kahi kope 3D pololei o kahi hau wili, ma ka hoʻolālā ʻana, ma ka nanoscale."
Ua hana ʻia ka hau wili artificial me ka hoʻohana ʻana i nā ʻano hana nanofabrication 3D hou loa kahi i hoʻopili ʻia ai nā nanowires liʻiliʻi i ʻehā mau papa i loko o kahi ʻano lattice, nona iho ka laulā ma lalo o ka laulā o ka lauoho kanaka.
Ua hoʻohana ʻia kekahi ʻano microscopy kūikawā i ʻike ʻia ʻo ka microscopy magnetic force, kahi mea i pili i ka magnetism, e nānā i nā uku magnetic i loaʻa ma ka hāmeʻa, e ʻae ana i ka hui e hahai i ka neʻe ʻana o nā magnets single-pole ma o ka hale 3D.
"He mea nui kā mākou hana no ka mea ke hōʻike nei ia e hiki ke hoʻohana ʻia nā ʻenehana paʻi 3D nanoscale e hoʻohālike i nā mea i hana pinepine ʻia ma o ka kemika," hoʻomau ʻo Kauka Ladak.
"I ka hopena, hiki i kēia hana ke hāʻawi i kahi ala e hana ai i nā metamaterials magnetic hou, kahi e hoʻonohonoho ʻia ai nā waiwai o nā mea ma ka kaohi ʻana i ke geometry 3D o kahi lattice artificial."
"ʻO nā mea mālama makeneka, e like me ka pā paʻa paʻa a i ʻole nā mea hoʻomanaʻo komo random magnetic, ʻo ia kekahi wahi i hiki ke hoʻopilikia nui ʻia e kēia holomua. ʻOiai ʻo nā mea hana o kēia manawa e hoʻohana wale ana i ʻelua o nā ana ʻekolu i loaʻa, kaupalena kēia i ka nui o ka ʻike e hiki ke mālama ʻia. ʻOiai hiki ke hoʻoneʻe ʻia nā monopoles a puni ka lattice 3D me ka hoʻohana ʻana i kahi kahua magnetic, hiki paha ke hana i kahi mea mālama 3D maoli e pili ana i ka hoʻopiʻi magnetic."
