    Experimental test of uncertainty relations for quantum mechanics on a circle

  • Original language description

    We rederive uncertainty relations for the angular position and momentum of a particle on a circle by employing the exponential of the angle instead of the angle itself, which leads to circular variance as a natural measure of resolution. Intelligent states minimizing the uncertainty product under the constraint of a given uncertainty in angle or in angular momentum turn out to be given by Mathieu wave functions. We also discuss a number of physically feasible approximations to these optimal states. Thetheory is applied to the orbital angular momentum of a beam of photons and verified in an experiment that employs computer-controlled spatial light modulators at both the state preparation and analyzing stages.

    Experimentální ověření relací neurčitosti pro kvantovou mechaniku na kruhu

  • Czech description

    Pro částici na kruhu jsou odvozeny relace neurčitosti pro úhel a moment hybnosti. Jak je ukázáno, tyto relace neurčitosti jsou minimalizovány Mathieu vlnovými funkcemi. Teoretický popis je aplikován na orbitální úhlový moment fotonových svazků a ověřen vexperimentu využívajícím prostorové modulátory světla pro přípravu stavu i následnou analýzu.
