Amongst those are optical molasses, evaporative cooling, and magneto-optical trap. The most important physical properties of cold atoms are stressed in an introduction to cold atom interferometry. The principles of cold atom gravity meter are explained to some extent. It has many benefits and better accuracy compared to classical gravimeters. Potential uses in geodesy, navigation, earth's gravity field mapping, as gravity wave detectors, and for testing fundamental gravitational laws and theories are also briefly discussed</dc:description><dc:description xml:lang="sl">V članku je najprej predstavljenih nekaj najpogosteje uporabljenih metod za hlajenje atomov: optične molase, hlajenje z izhlapevanjem atomov in magneto-optično past. S kvantnimi lastnostmi hladnih atomov je razložena interferometrija hladnih atomov. To je glaven princip, ki omogoča zelo natančno merjenje pospeškov s hladnimi atomi. Poudarek je na merjenju gravitacijskega pospeška, saj ima tak instrument veliko prednosti pred klasičnim. Za konec so na kratko predstavljene možne uporabe gravimetrov na hladne atome v geodeziji, navigaciji, za mapiranje zemljinega gravitacijskega polja, kot detektorji gravitacijskih valov in za testiranje fundamentalnih zakonov gravitacije</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-72CWAXPV"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-72CWAXPV" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-72CWAXPV/0aacc4f-2bb0bc-0d5c-9f118b846642c-20/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-72CWAXPV/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-72CWAXPV" /></ore:Aggregation></rdf:RDF>
