Lub kiv ntawm ib qho hluav taws xob tsis tuaj yeem soj ntsuam tas li yam tsis hloov nws, yog li nws yuav tsum tau ntsuas ua ntej thiab tom qab kev sim los tswj nws lub xeev quantum. Qhov kev ntsuas no qhia seb lub kiv nce lossis nqis, tab sis ib puag ncig sib nqus ib puag ncig tuaj yeem siv tau txhua lub sijhawm.

Puas yog qhov hloov pauv ntawm cov khoom puas hloov tau?

Txhua cov ntsiab lus tseem ceeb muaj cov cuab yeej hu ua spin, uas tsis txhais tau tias lawv tig mus ncig, tab sis nws txhais tau tias lawv muaj kev taw qhia hauv qhov chaw thiab lub zog ntawm lub kaum sab xis. … Qhov no txhais tau hais tias peb tuaj yeem hloov txoj kev tig ntawm kev ntsuas tsuas yog ntsuas nws.

Dab tsi ua rau muaj kev hloov pauv electron?

Analogously, hauv quantum mechanics, ib tus tuaj yeem siv "torque" ntawm electron spin degree ntawm kev ywj pheej los ntawm tso cov hluav taws xob hauv qhov chaw sib nqus Qhov no yuav ua rau lub spin mus rau hauv ib qho kev taw qhia sib txawv. Txhawm rau muab ob npaug rau qhov nrawm nrawm ib qho yuav tsum muab ob npaug rau lub zog ntawm daim ntawv thov sib nqus.

Koj tswj tau hluav taws xob li cas?

Nws paub tias nyob rau hauv cov ntaub ntawv uas muaj zog spin-orbital kev sib cuam tshuam nws muaj peev xwm tswj tau lub electron spin yam tsis tau hloov lub magnetic teb. Hloov chaw, kev tswj hwm tuaj yeem ua tiav los ntawm siv lub sijhawm hluav taws xob ntawm qhov tshwj xeeb xaiv zaus.

Koj puas tuaj yeem nres lub tshuab hluav taws xob los ntawm kev tig?

Tsis yog, nws tsis tuaj yeem nres ib lub tshuab hluav taws xob. vim qhov tseeb yooj yim, nws yuav tsum ua raws li Heisenberg kev sib raug zoo nrog rau qhov chaw thiab lub zog. Hauv qhov xwm txheej loj (kev xav) peb tuaj yeem ntsuas cov hluav taws xob lub zog nrog qhov tseeb.
