nyob ib ncig ntawm 150 nano Kelvin

Xav txog qhov no, peb tuaj yeem mus zero li cas?

Ntawm lub cev tsis tuaj yeem ncav cuag qhov kub ntawm xoom kelvin, los yog rho tawm 459.67 degrees Fahrenheit (rho tawm 273.15 degrees Celsius), atoms yuav tsum tsis txhob txav. Yog li ntawd, tsis muaj dab tsi ua tau yuav txias dua tsis muaj tseeb ntawm Kelvin scale.

Tsis tas li ntawd, yuav ua li cas tshwm sim ntawm qhov zero? Tsis muaj tseeb yog qhov ntsuas kub qis tshaj plaws uas tsis muaj dab tsi yuav txias dua thiab tsis muaj lub zog cua sov nyob hauv cov khoom. Tsis muaj tseeb yog lub ntsiab lus ntawm qhov tseem ceeb ntawm cov xwm txheej muaj qhov kev vibrational tsawg, khaws cia tsuas yog quantum mechanical, xoom -point zog-induced particle motion.

Tsuas yog li ntawd, qhov twg yog qhov tsis muaj tseeb?

Tsis muaj tseeb Tsis tuaj yeem ua tiav, txawm hais tias nws tuaj yeem ncav cuag qhov kub thiab txias los ntawm kev siv cov khoom siv cryocoolers, dilution tub yees, thiab nuclear adiabatic demagnetization. Kev siv laser txias tau ua kom kub tsawg tshaj li ib billionth ntawm ib kelvin.

Puas electrons txav ntawm zero kiag?

Nyob ze tsis muaj tseeb , electrons "mus txuas ntxiv mus ncig" hauv atoms, hais tias quantum physicist Christopher Foot ntawm University of Oxford. Ntxiv mus, txawm nyob rau tsis muaj tseeb , atoms yuav tsis nyob ruaj ruaj. Lawv yuav "jiggle txog," tab sis yuav tsis muaj zog txaus los hloov lub xeev. Nws lub zog yog yam tsawg kawg nkaus.
