Svetlo je využívané pre manipuláciu s atómami a na štúdium ich vlastností. Počas posledných desaťročí táto oblasť výskumu výrazne expandovala a priniesla dramatické objavy, ktoré viedli k možnostiam chladenia atómov do extrémne nízkych kinetických energií, či k udržaniu izolovaných atomárnych obláčikov vo vákuových systémoch desiatky sekúnd. V tomto článku uvádzame základné princípy chladenia elementárnych častíc svetlom., The laser cooling of elementary particles has become an essential part of quantum optics experiments studying the interaction of light and matter at its fundamental level. Over the last few decades, laser cooling has enabled dramatic developments in several research areas, including the understanding of new regimes of matter or the unprecedented accuracy of atomic clocks. We present a brief introduciton to laser cooling techniques by the explanation of basic underlying principles, followed by the discussion of Doppler cooling and a few prominent sub-Doppler cooling techniques., Lukáš Slodička., and Obsahuje seznam literatury
The vast majority of physical objects we deal with are almost exclusively made of atoms. Due to their discrete level structure, single atoms have proved to be excellent emitters of nonclassical light, i.e. single photons. We demonstrate experimentally that this nonclassical behaviour is preserved when scaling up the number of atoms in the source ensemble by several orders of magnitude., Lukáš Slodička, Ondřej Číp a Radim Filip., and Obsahuje bibliografické odkazy
