Yog koj txhais k - qhov chaw , zoo li hauv cov ntaub ntawv qis dua k , nws feem ntau yog hais txog spatial-theem qhov chaw , lwm yam hu ua reciprocal qhov chaw . Nws yog qhov pib ntawm Fourier hloov ntawm tiag qhov chaw . Hauv k - qhov chaw lawv sawv cev los ntawm ib tug wavenumber k , uas yog sib npaug rau 2 * pi / wavelength.

Tom qab ntawd, Quantum momentum yog dab tsi?

Quantum zog . Ib tug tshiab quantum -mechanicalmodel tau tsim tawm uas tso cai rau cov lub zog ntawm quantum particles yuav tsum ntsuas siv ib tug variant ntawm lub classical time-of-flight. Springer. Quantum mechanics yog ib qho kev vam meej ntawm kev nkag siab txog lub ntiaj teb lub cev ntawm cov nplai me me.

Kuj Paub, lub zog qhov chaw nthwv dej yog dab tsi? Yog hais tias ib tug xaiv lub eigenfunctions ntawm lub lub zog tus neeg teb xov tooj raws li cov txheej txheem muaj nuj nqi , qhov tshwm sim wavefunction (k) hais tias yog tus yoj ua haujlwm hauv qhov chaw nrawm . Ib qho tshwj xeeb ntawm quantum mechanics yog tias cov theem sib txawv tuaj yeem tuaj yeem sib txawv: discrete-variable, rotor, thiab txuas ntxiv-nruab nrab.

Dhau li ntawm no, dab tsi quantum mechanics qhia peb txog txoj haujlwm thiab lub zog?

Dawb particle hauv quantum mechanics , qhov teeb meem pub dawb tau piav qhia los ntawm kev ua haujlwm nthwv dej. Cov khoom particle ntawm qhov teeb meem tshwm sim thaum peb ntsuas nws txoj hauj lwm thiab ceev. Txoj Cai Uncertainty hais tias ob qho tib si txoj hauj lwm thiab cov lub zog tsis tuaj yeem ntsuas ib txhij nrog kev ua tiav.

Koj txhais li cas los ntawm reciprocal lattice?

Nyob rau hauv physics, lub reciprocal lattice sawv cev rau Fourier hloov ntawm lwm tus daim kab xev (feem ntau yog Bravais daim kab xev ). Nyob rau hauv neutron thiab X-ray diffraction, vim lub Laueconditions, lub zog sib txawv ntawm cov tuaj thiab diffractedX-rays ntawm ib tug siv lead ua yog ib tug reciprocal lattice vector.
