Hōʻike ka poʻe ʻepekema i ka hoʻokumu ʻia ʻana o nā polaritons hawewe-mea i loko o ka lattice optical, kahi ʻike hoʻokolohua e hiki ai i nā noiʻi o ka ʻepekema quantum a me ka paradigm ʻenehana ma o ka simulation quantum pololei me ka hoʻohana ʻana i nā atom ultracold.
ʻIke ʻia o Matter-Wave Polaritons e hoʻomālamalama hou i ka Photonic Quantum Technologies
ʻO ka noiʻi i paʻi ʻia ma ka puke pai Nature Physics e hāʻawi i kahi paepae hou no ka 'kuantum revolution lua.'
ʻO ka hoʻomohala ʻana i nā paepae hoʻokolohua e holomua ana i ke kahua o ka ʻepekema quantum a me ka ʻenehana (QIST) e hele mai me kahi pūʻulu kūʻokoʻa o nā pono a me nā luʻi maʻamau i nā ʻenehana e kū mai ana. ʻO nā mea noiʻi ma ke Kulanui ʻo Stony Brook, alakaʻi ʻia e Dominik Schneble, PhD, hōʻike i ka hoʻokumu ʻia ʻana o nā polaritons hawewe-mea i loko o ka lattice optical, kahi ʻike hoʻokolohua e ʻae ai i nā noiʻi o kahi paradigm QIST kikowaena ma o ka hoʻohālikelike quantum pololei me ka hoʻohana ʻana i nā atom ultracold. Hoʻolālā ka poʻe ʻepekema ʻo kā lākou mau quasiparticles hou, ka mea e hoʻohālikelike i nā kiʻi paʻi kiʻi i loko o nā mea a me nā mea hana akā e hoʻopuni ana i kekahi o nā paʻakikī paʻakikī, e pōmaikaʻi i ka hoʻomohala hou ʻana o nā kahua QIST i mākaukau e hoʻololi i ka ʻenehana kamepiula a me ka ʻenehana kamaʻilio.
Ua kikoʻī ʻia nā ʻike noiʻi ma kahi pepa i paʻi ʻia ma ka puke pai ʻO Physics Kino.
Hoʻomālamalama ka haʻawina i nā waiwai polariton koʻikoʻi a me nā mea e pili ana i nā ʻano kino he nui, a wehe ia i nā mea hou no ka noiʻi ʻana i ka mea polaritonic quantum matter.
ʻO kahi paʻakikī koʻikoʻi i ka hana ʻana me nā paena QIST e pili ana i ka photon, ʻoiai hiki i nā kiʻi kiʻi ke lawe maikaʻi i ka ʻike quantum ʻaʻole lākou e launa pū kekahi me kekahi. ʻO ka loaʻa ʻole o ia mau pilina pili pū kekahi e pale i ka hoʻololi ʻana o ka ʻike quantum ma waena o lākou. Ua loaʻa i nā kānaka ʻepekema kahi ala e hoʻopuni ai i kēia ma ka hoʻopili ʻana i nā kiʻi kiʻi i nā mea hauʻoli ʻoi aku ka nui o nā mea, pēlā e hana ai i nā polaritons, chimera-like hybrids ma waena o ka māmā a me ka mea. ʻO ka hui ʻana ma waena o kēia mau quasiparticles kaumaha a laila e hiki ai i nā kiʻi ke hana pono. Hiki i kēia ke hoʻokō i nā hana puka quantum e pili ana i ka photon a ma hope o kahi ʻōnaehana QIST holoʻokoʻa.
Eia nō naʻe, ʻo kahi luʻi nui ka palena o ke ola ʻana o kēia mau polariton i hoʻokumu ʻia ma muli o ko lākou hui ʻana i ka radiative i ke kaiapuni, kahi e alakaʻi ai i ka palaho a me ka decoherence.
Hōʻike ʻia ka ʻike noʻeau o ka ʻimi noiʻi ma ka haʻawina polariton i nā ʻātoma i loko o kahi lattice optical e hana ana i kahi pae insulating (hema); ʻo nā ʻātoma e huli ana i polariton hawewe-mea ma o ka hoʻopili ʻana i ka ʻūhā i hoʻopili ʻia e ka radiation microwave i hōʻike ʻia e ke kala ʻōmaʻomaʻo (waena); e lilo ana nā polaritons i mea paʻa a hoʻokumu i kahi ʻano superfluid no ka hoʻopili ʻana i ka ʻūhā ikaika (akau).

Wahi a Schneble a me nā hoa hana, kā lākou noiʻi polariton i paʻi ʻia e pale i nā palena i hoʻokumu ʻia e ka pohō ʻole. ʻO nā hiʻohiʻona photon o kā lākou polariton e lawe piha ʻia e nā nalu mea atomic, no laila ʻaʻole i loaʻa nā kaʻina pohō makemake ʻole. Wehe kēia hiʻohiʻona i ke komo ʻana i nā regime parameter ʻaʻole hiki, a ʻaʻole paha, hiki ke loaʻa i nā ʻōnaehana polaritonic photon.
"Ua lanakila ka hoʻomohala ʻana i nā mīkini quantum i ke kenekulia i hala, a ʻo ka 'lua quantum revolution' i ka hoʻomohala ʻana o QIST a me kāna mau noi ke holo maikaʻi nei a puni ka honua, me nā hui e like me IBM, Google a me Amazon," wahi a Schneble, he Kumu ma ka 'Oihana Physics a me Astronomy ma ke Koleke o na Noe a me na 'Epekema. "Ke hōʻike nei kā mākou hana i kekahi mau hopena mechanical quantum e makemake nui ʻia no nā ʻōnaehana quantum photonic e puka mai ana ma QIST mai ka semiconductor nanophotonics a i ka circuit quantum electrodynamics."
Ua alakaʻi ka poʻe noiʻi ʻo Stony Brook i kā lākou hoʻokolohua me kahi paepae e hōʻike ana i nā ʻātoma ultracold i loko o ka lattice optical, kahi ʻāina kūpono e like me ka hua manu i hana ʻia e nā nalu kū o ka mālamalama. Me ka hoʻohana ʻana i kahi mea hoʻolaʻa i hoʻolaʻa ʻia e hōʻike ana i nā lasers like ʻole a me nā kahua hoʻokele a me ka hana ʻana i ka wela nanokelvin, ua hoʻokō lākou i kahi hiʻohiʻona i hoʻopaʻa ʻia nā ʻātoma i loko o ka lattice "ʻaʻahu" iā lākou iho me nā ao o ka hau hau i hana ʻia me nā nalu mea palupalu.
Ua ʻike ka hui, ʻo ia ka hopena, lilo nā ʻāpana polaritonic i ʻoi aku ka paʻa. Ua hiki i nā mea noiʻi ke ʻimi pololei i ko lākou hale i loko o ka hoʻoluliluli mālie ʻana i ka lattice, no laila ke komo ʻana i nā haʻawina o nā nalu mea a me ka hoʻoulu ʻana i ka lattice atomic. Ke waiho wale ʻia, lele nā polaritona hawewe-mea i ka lattice, pili pū kekahi me kekahi, a hana i nā ʻāpana paʻa o ka mea quasiparticle.
"Me kā mākou hoʻokolohua ua hana mākou i kahi simulation quantum o kahi ʻōnaehana exciton-polariton i loko o kahi aupuni hou," wehewehe ʻo Schneble. "ʻO ka ʻimi e hana i kēlā analogue’ simulations, which in addition areAnalog` ma ke ʻano e hiki ke hoʻopaʻa wale ʻia nā ʻāpana kūpono, ʻo ia iho kahi kuhikuhi koʻikoʻi i loko o QIST.
