Coherent yoj

Peb yog surrounded los ntawm cov khoom ntawm lub niaj zaus loj; Peb paub yuav ua li cas loj peb lub cev; peb yeej paub tseeb tias ib tug lub rooj zaum yog nyiam rau ib tug neeg xwb. Nyob rau hauv mikrokvantovom ntiaj teb no, lub ntiaj teb cov me tej yam, txhua yam mas, tsawg prosaic: ib lub rooj zaum, txo mus rau ib tug ob peb puas billion lub sij hawm thiab siv qhov luaj li cas ntawm ib tug atom loses nws ntshiab kav, raws li zoo raws li tej me raws li qhov kev kawm. Thiab tag nrho cov khoom yuav haum nyob rau hauv tib lub qhov chaw, nyob rau tib lub sij hawm yam tsis teeb liab ntsais nrog txhua lwm yam. Yog vim li cas? Nyob rau hauv lub ntiaj teb no quantum khoom - vuag, uas txeem mus rau hauv txhua lwm yam, yog li ib tug yuav zoo tau ib lub rooj zaum los zaum, thiab tsib thiab kaum thiab nees nkaum. Tej tsis yog hu ua coherent tsis.

Coherence txhais tau tias cov kev sib raug zoo, cov taub hau (cohaerens - losis tswvyim dabtsi, yog vim). Coherent tsis, ntsig txog, muaj tib zaus, cov tib amplitude, cov tib theem txawv. Qhov no match featured ib tug monochromatic yoj, unlimited yog nyob rau hauv lub sij hawm los yog nyob rau hauv qhov chaw.

Mus hnov tus tsis meej pem ntawm kev sim tej yam (khoom) yog tsis tsuas tsim nyog los txo, tab sis kuj txias heev, piv txwv li, understate lub chaotic suab ntawm cov atoms. Thiab nws tsis yog cia li hais txog lub "rho tawm" thiab txog billionths ntawm ib tug degree Kelvin. Wave thaj chaw ntawm lub tib lub rooj zaum yuav tsum ua pom ntawm incredibly tsawg kub - 45 K.

Ib tug interesting feature ntawm qhov tsis - muaj peev xwm los tsim ib tug coherent, ie, orderly thiab hauj lwm ua ke zoo. Piv txwv li, coherent tsis nyob rau hauv lub sij hawm - music. Yog, lub suab paj nruag! Txhua suab-sounding melodies, nws ntev, nws zaus, nws qhov siab - nruj kev txiav txim thiab xov xwm. Lub weakening ntawm coherence yog ntaus nqi los ntawm peb li sounding fake thiab tsis coherence - raws li cov suab nrov. Hais tias coherence distinguishes music los ntawm rambling thiab tej zaum annoying suab.

Thiab khoom ntawm lub quantum ntiaj teb no coherence muab tshiab zoo li ntawd tseem ceeb los mus tsim thiab tsim kiag cov ntaub ntawv tshiab, tej zaum radically hloov uas twb muaj lawm technologies.

Tsis los ntawm lub caij 40% ntawm cov Nobel Prizes nyob rau hauv lub dhau los lawm ob xyoo lawm yog kev cob cog rua coherent phenomena: txias atoms, kua Helium thiab superconductors.

Txoj kev rau cov coherent tsis:

• tau txais lub cuab tam (division suab yoj los ntawm qhov chaw mus rau hauv ob);
• Pem hauv ntej division.

Decimeter yog hom twg millimeter electromagnetic vuag yog siv mas nyob rau hauv kev sib txuas lus thiab Electronics Engineers. Tab sis dhau tus xeem 15-20 xyoo, lawv siv tau nce nyob rau hauv uas tsis yog-tshuaj chaw, thiab tsuas yog nyob rau hauv ib thiab tshuaj. Ib tug luv luv-wavelength bands siv ua ntej lawm, txij thaum lub foundations ntawm qhov kev to taub tau oscillations.

Koj twb tau hnov txog lub cev txoj kev kho? Ntawm chav kawm - yog. Qhov no - tus thawj hauv cheeb tsam ntawm qhov kev siv kev to taub tau tsis nyob rau hauv cov tshuaj. Warming cov ntaub so ntswg tso cai (thiab tam sim no pub) rau accelerate lub tshuaj tiv thaiv (ob tshuaj thiab biochemical) tshaj twb txiav txim thiab cov nyhuv ntawm physiotherapy. Cov tsis tau txeem ntxaum mus rau hauv cov kab mob, ncaj qha rau hauv cov ntaub so ntswg nyob rau hauv uas lawv qhia.

Thiab yuav ua li cas muaj nuj nqis foundations hyperthermia! Rov qab nyob rau hauv lub sixties ntawm lub xeem caug xyoo peb tsim: coherent tsis tau puas phem hlav.

Tsis surprise hnub no, thiab laser phais, uas siv rau tag nrho cov tib coherent tsis, tiam sis tsuas yog nyob rau hauv ib tug heev nqaim beams muaj peev xwm ntawm kev rhuav tseg ob leeg nqaij mos thiab pob txha. Muaj yog muaj feem xyuam ntau yam lasers nrog txawv frequencies, nyob ntawm seb qhov xwm ntawm tus hauj lwm thiab ntaub so ntswg. Zoo "bloodless" phais, tom qab uas tus neeg mob zaug sai.

Analysis ntawm tawm tshiab qhov chaw ntawm daim ntawv thov ntawm vuag ntawm coherence tso cai rau kom xav tias tshuaj thiab biology sai sai no yuav tsum yog tus tseem ceeb thaj chaw ntawm daim ntawv thov.
