Low-temperature sensitivity might be manipulated by tailoring the interactions between probe and sample. Unfortunately, the tunability of these interactions is usually very restricted. Here, we focus on a more practical solution to boost thermometric precision \u2013 driving the probe. Specifically, we solve for the limit cycle of a periodically modulated linear probe in an equilibrium sample. We treat the probe-sample interactions <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mi>e<\/mml:mi><mml:mi>x<\/mml:mi><mml:mi>a<\/mml:mi><mml:mi>c<\/mml:mi><mml:mi>t<\/mml:mi><mml:mi>l<\/mml:mi><mml:mi>y<\/mml:mi><\/mml:math> and hence, our results are valid for arbitrarily low temperatures <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mi>T<\/mml:mi><\/mml:math> and any spectral density. We find that weak near-resonant modulation strongly enhances the signal-to-noise ratio of low-temperature measurements, while causing minimal back action on the sample. Furthermore, we show that near-resonant driving changes the power law that governs thermal sensitivity over a broad range of temperatures, thus `bending' the fundamental precision limits and enabling more sensitive low-temperature thermometry. We then focus on a concrete example \u2013 impurity thermometry in an atomic condensate. We demonstrate that periodic driving allows for a sensitivity improvement of several orders of magnitude in sub-nanokelvin temperature estimates drawn from the density profile of the impurity atoms. We thus provide a feasible upgrade that can be easily integrated into low-<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mi>T<\/mml:mi><\/mml:math> thermometry experiments.<\/jats:p>","DOI":"10.22331\/q-2022-05-03-705","type":"journal-article","created":{"date-parts":[[2022,5,3]],"date-time":"2022-05-03T13:27:46Z","timestamp":1651584466000},"page":"705","update-policy":"https:\/\/doi.org\/10.22331\/q-crossmark-policy-page","source":"Crossref","is-referenced-by-count":14,"title":["Bending the rules of low-temperature thermometry with periodic driving"],"prefix":"10.22331","volume":"6","author":[{"given":"Jonas","family":"Glatthard","sequence":"first","affiliation":[{"name":"Department of Physics and Astronomy, University of Exeter, Exeter EX4 4QL, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis A.","family":"Correa","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy, University of Exeter, Exeter EX4 4QL, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"9598","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"key":"0","doi-asserted-by":"publisher","unstructured":"Aron E.
