This a reminder of today's two hybrid theory seminars that we are having. The first seminar will be given by Peter Meinzinger at 9 am (EDT) in CC<span> </span><span style="background-color: rgb(255, 255, 0);"><b>F224-225</b></span>, and Srimoyee Sen will give
the second seminar at 1 pm (EDT) in CC<span> </span><span style="background-color: rgb(255, 255, 0);"><b>L102</b></span>. We would like to highlight that Srimoyee Sen's seminar is one of the ODU + JLab joint position interviews. If you will be on-site and
are comfortable doing so, please join us for both seminars. Otherwise, each seminar will also be provided virtually on our usual ZoomGov link:<span> </span><a href="https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09" id="LPlnk326365" style="">https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09</a><br>

Electron--proton collisions are an important mode for, e.g., determination of parton distribution functions, making it necessary to understand the dynamics and kinematics of these collisions. To achieve highest precision in the different observables it is necessary
to develop simulations of these events which leverage the Fixed Order calculations and match them to the parton showers. I will review the status of the simulation of high-virtuality DIS production modes in the event generator community and make the case for
a simulation of the complementary photoproduction modes. The latter mode will allow for an understanding of the full dynamics of the system and solve the problem of the different scales. I will present the current status of photoproduction at NLO accuracy
in the Sherpa event generator and discuss how to merge the two modes to arrive at a complete picture of electron--proton collision in the future.</div>

<div class="ContentPasted0" style="font-family: Calibri, Arial, Helvetica, sans-serif;" dir="auto">
Dense astrophysical objects like neutron stars allow us to explore the phase diagram of QCD at very low temperature and very high density. The outer layers of the star are made up of nuclear matter and the inner core of quark matter. A natural question that
follows is whether nuclear matter and quark matter are necessarily separated by a phase boundary. I discuss how new insight from topological phases in quantum materials support the existence of such a phase boundary. I also discuss how future lattice simulations
may help us reach a conclusive answer to this question.</div>
