<div style="margin-top:0; margin-bottom:0">Scientific Fika is an event where junior scientists (PhD students, postodocs and MSc students) give talks and listen to interesting science presented by other juniors! It is meant to bring together junior scientists
in an informal setting to discuss topics they are interested in. Everyone is welcome to attend and to give talks! The talks can be about any science
<font style="font-family:Helvetica,Arial,sans-serif,serif,"EmojiFont"" face="Helvetica,Arial,sans-serif">
you are curious about. They are meant to be for a broad audience and accessible for various background/levels to have great discussions.</font> After the talk the audience asks questions and we have some nice fika!

<div style="margin-top:0; margin-bottom:0">Currently, due to the covid-regulations, the talks are online but we hope to get back to physical meetings (with fika) soon! The next talk is this
<b>Friday; February 4th at 4.00 pm</b>, see the invitation and zoom-link below.</div>

<font style="font-size:12pt"><font color="#000000"><b>Abstract: </b></font><font color="#000000"><span style="font-weight:normal">The traditional way to calculate observables in quantum field theory (QFT) is to use perturbation theory. However, some quantum
field theories are strongly coupled, meaning that the perturbation parameters are large and perturbation theory breaks down. I will describe holography, a powerful technique for performing computations in strongly coupled QFT, in which the QFT is related to
a higher-dimensional theory of gravity. Most of the talk will be spent explaining the kinds of observables that we typically want to calculate in QFT and how holography can help. I will then give an example application from my research: the application of
holography to Weyl-semimetals.</span></font></font><br>
