Mas­ter The­sis (Theo­ry): Uncer­tain­ty rela­ti­ons in quan­tum-opti­cal light-mat­ter inter­ac­tions

Pro­ject descrip­ti­on
Modern quan­tum sen­sors on the basis of ultra-cold atoms allow for an unpre­ce­den­ted expe­ri­men­tal accu­ra­cy and have shown to be use­ful in fun­da­men­tal sci­ence and real-world app­li­ca­ti­ons ali­ke. With the pur­su­it of minia­tu­riz­a­ti­on and advan­cing expe­ri­men­tal fines­se, tes­ting the bounda­ries of what theo­re­ti­cal phy­sics can pre­dict has beco­me via­ble. In this mas­ter pro­ject, we will ask the ques­ti­on, what are the fun­da­men­tal uncer­tain­ties in using ato­mic quan­tum sen­sors? Clear­ly, the Hei­sen­berg uncer­tain­ty rela­ti­on is one part of the sto­ry. But it lea­ves the effects of, say, tem­pe­ra­tu­re, mate­ri­al-modi­fied vacu­um fluc­tua­tions and com­pli­ca­ted sys­tem-bath cou­plings in none­qui­li­bri­um situa­tions sim­ply untouched. Due to the lat­ter, the pre­cisi­on that is actual­ly achie­ved often exceeds Heisenberg’s rela­ti­on. We aim to explo­re that dis­crepan­cy.

Working with us, you will learn more about:
Quan­tum Vacu­um and its macro­scopic effects
Light-mat­ter inter­ac­tion and none­qui­li­bri­um sta­tis­ti­cal phy­sics
Sol­ving equa­tions (asym­pto­ti­cal­ly) in order to gain phy­si­cal intui­ti­on

Open­ness to work with ana­ly­ti­cal as well as nume­ri­cal mathe­ma­ti­cal tools. Solid back­ground in theo­re­ti­cal phy­sics, in par­ti­cu­lar quan­tum mecha­nics, sta­tis­ti­cal phy­sics, and elec­tro­dy­na­mics, is hel­pful.

Peop­le with an inter­na­tio­nal histo­ry or diver­se back­ground and iden­ti­ty are spe­ci­fi­cal­ly encou­ra­ged to app­ly.
