Nā polokalamu liʻiliʻi a ʻoi aku ka maikaʻinā lasers
Ua hana nā mea noiʻi o ka Rensselaer Polytechnic Institute i kahihāmeʻa laserʻo ia wale nō ka laulā o ka lauoho kanaka, ka mea e kōkua i nā physicists e aʻo i nā waiwai kumu o ka mea a me ka mālamalama. ʻO kā lākou hana, i paʻi ʻia ma nā puke pai ʻepekema hanohano, hiki ke kōkua i ka hoʻomohala ʻana i nā lasers ʻoi aku ka maikaʻi no ka hoʻohana ʻana ma nā kahua mai ka lāʻau lapaʻau a hiki i ka hana ʻana.

ʻO kalaserHana ʻia ka hāmeʻa me kahi mea kūikawā i kapa ʻia he insulator topological photonic. Hiki i nā insulator topological photonic ke alakaʻi i nā photons (nā nalu a me nā ʻāpana e hana ana i ka mālamalama) ma o nā interfaces kūikawā i loko o ka mea, me ka pale ʻana i kēia mau ʻāpana mai ka hoʻopuehu ʻana i loko o ka mea ponoʻī. Ma muli o kēia waiwai, hiki i nā insulator topological ke hana pū i nā photons he nui. Hiki ke hoʻohana ʻia kēia mau mea hana ma ke ʻano he "simulators quantum" topological, e ʻae ana i nā mea noiʻi e aʻo i nā hanana quantum - nā kānāwai kino e hoʻomalu ana i nā mea ma nā unahi liʻiliʻi loa - ma nā mini-labs.
"ʻO katopology photonicHe mea kū hoʻokahi ka insulator a mākou i hana ai. Hana ia i ka mahana o ka lumi. He holomua nui kēia. Ma mua, hiki ke hana ʻia kēlā mau haʻawina me ka hoʻohana ʻana i nā lako nui a pipiʻi e hoʻolulu i nā mea i loko o kahi vacuum. ʻAʻole i loaʻa i nā LABS noiʻi he nui kēia ʻano lako, no laila hiki i kā mākou hāmeʻa ke hiki i nā poʻe hou aku ke hana i kēia ʻano noiʻi physics kumu i loko o ka lab, "wahi a Rensselaer Polytechnic Institute (RPI) ke kumu kōkua ma ka 'Oihana ʻEpekema Mea a me Engineering a me ka mea kākau kiʻekiʻe o ke aʻo ʻana. He liʻiliʻi ka nui o ka laʻana o ke aʻo ʻana, akā hōʻike nā hopena ua hōʻike ka lāʻau hou i ka pono koʻikoʻi i ka mālama ʻana i kēia maʻi genetic laha ʻole. Ke kakali nei mākou i ka hōʻoia hou ʻana i kēia mau hopena i nā hoʻokolohua lapaʻau e hiki mai ana a hiki ke alakaʻi i nā koho lapaʻau hou no nā maʻi me kēia maʻi. "ʻOiai ua liʻiliʻi ka nui o ka laʻana o ke aʻo ʻana, hōʻike nā ʻike ua hōʻike kēia lāʻau hou i ka pono koʻikoʻi i ka mālama ʻana i kēia maʻi genetic laha ʻole. Ke kakali nei mākou i ka hōʻoia hou ʻana i kēia mau hopena i nā hoʻokolohua lapaʻau e hiki mai ana a hiki ke alakaʻi i nā koho lapaʻau hou no nā maʻi me kēia maʻi.
"He ʻanuʻu nui kēia i mua i ka hoʻomohala ʻana i nā lasers no ka mea ʻo ka paepae o kā mākou mea hana mahana lumi (ka nui o ka ikehu e pono ai e hana ia) he ʻehiku manawa haʻahaʻa ma mua o nā mea hana cryogenic ma mua," wahi a nā mea noiʻi. Ua hoʻohana nā mea noiʻi ʻo Rensselaer Polytechnic Institute i ke ʻano hana like i hoʻohana ʻia e ka ʻoihana semiconductor e hana i nā microchips e hana i kā lākou mea hana hou, ʻo ia hoʻi ke kau ʻana i nā ʻano mea like ʻole ma ka papa, mai ka pae atomika a i ka pae molekala, e hana i nā ʻano kūpono me nā waiwai kikoʻī.
E hana i kamea hana lasers, ua ulu nā mea noiʻi i nā papa lahilahi loa o ka selenide halide (he kristal i hana ʻia me ka cesium, ke kēpau a me ka chlorine) a ua kālai ʻia nā polymers i kālai ʻia ma luna o lākou. Ua hoʻopili lākou i kēia mau papa kristal a me nā polymers ma waena o nā mea oxide like ʻole, e hopena ana i kahi mea ma kahi o 2 microns ka mānoanoa a me 100 microns ka lōʻihi a me ka laulā (ʻo ka laulā awelika o ka lauoho kanaka he 100 microns).
I ka wā i hoʻomālamalama ai nā mea noiʻi i kahi laser ma ka hāmeʻa lasers, ua ʻike ʻia kahi ʻano triangle luminous ma ka interface hoʻolālā mea. Hoʻoholo ʻia ke ʻano e ka hoʻolālā hāmeʻa a ʻo ia ka hopena o nā ʻano topological o ka laser. "He mea hoihoi ka hiki ke aʻo i nā hanana quantum ma ka mahana o ka lumi. Hōʻike ka hana hou a Polofesa Bao e hiki i ka ʻenekinia mea ke kōkua iā mākou e pane i kekahi o nā nīnau nui loa i ka ʻepekema." wahi a ke poʻo ʻenekinia o Rensselaer Polytechnic Institute.
