Hannah Elfner

Hannah Petersen was a physics student at the Goethe University Frankfurt. She graduated in 2006, and remained at Goethe for her doctoral research supported by Deutsche Telekom. Her doctoral research involved an integrated Boltzmann approach to the collisions of heavy ions.{{Cite thesis|last=Petersen|first=Hannah|url=https://nbn-resolving.org/urn:nbn:de:hebis:30-65851|title=An integrated Boltzmann + hydrodynamics approach to heavy ion collisions|date=2009|publisher=Universitätsbibliothek Johann Christian Senckenberg |language=en|oclc=1184374061}} Heavy ion conditions give rise to a strongly interacting state matter known as the quark–gluon plasma, which is similar to the matter founded in the moments following the Big Bang.{{Cite web|title=Heinz Maier-Leibnitz Prizes 2016|url=https://www.dfg.de/en/funded_projects/prizewinners/maier_leibnitz_prize/2016/index.html|access-date=2022-01-05|website=www.dfg.de|language=en}} Within this phase, the plasma expands explosively at extremely high pressure.{{Cite web|date=2018-05-30|title=Young physicist Hannah Petersen receives renowned award in Venice|url=https://aktuelles.uni-frankfurt.de/englisch/young-physicist-hannah-petersen-receives-renowned-award-in-venice/|access-date=2022-01-05|website=Aktuelles aus der Goethe-Universität Frankfurt|language=de-DE}} Petersen was amongst the first researchers to recognise that the pathway of these explosions was impacted by density and temperature.{{Cite web|title=Heinz Maier-Leibnitz Prizes 2016|url=https://www.dfg.de/en/funded_projects/prizewinners/maier_leibnitz_prize/2016/index.html|access-date=2022-01-05|website=www.dfg.de|language=en}} After earning her doctorate she joined Duke University as a Alexander von Humboldt Foundation Feodor Lynen fellow.{{Cite web|title=Dr. Hannah Petersen Appointed as Visiting Assistant Professor|url=https://physics.duke.edu/news/dr-hannah-petersen-appointed-visiting-assistant-professor|access-date=2022-01-05|website=Department of Physics|date=15 July 2011 |language=en}}

Elfner develops dynamical computation simulations to better understand high energy conditions and the quark–gluon plasma. She became interested in the influence of the initial and final states on the trajectory of heavy ion collisions.{{Cite web|title=Dr. Hannah Petersen Appointed as Visiting Assistant Professor|url=https://physics.duke.edu/news/dr-hannah-petersen-appointed-visiting-assistant-professor|access-date=2022-01-05|website=Department of Physics|date=15 July 2011 |language=en}} To quantitatively evaluate the impact of these boundary conditions, she adopted an event-by-event strategy that makes use of transport theory.{{Cite web|title=Dr. Hannah Petersen Appointed as Visiting Assistant Professor|url=https://physics.duke.edu/news/dr-hannah-petersen-appointed-visiting-assistant-professor|access-date=2022-01-05|website=Department of Physics|date=15 July 2011 |language=en}} She developed a hadronic transport approach known as SMASH (Simulating Many Accelerated Strongly-interacting Hadrons).{{Cite web|title=Quark Matter 2018|url=https://indico.cern.ch/event/656452/contributions/2869811/| url-status=live | archive-url=https://ghostarchive.org/archive/20220105/https://indico.cern.ch/event/656452/contributions/2869811/| archive-date=2022-01-05|access-date=2022-01-05|website=Indico}}{{cbignore}} SMASH is part of the National Science Foundation JETSCAPE framework.{{Cite web|title=Principal Investigators|url=https://elements.science/about-us/principle-investigators/| url-status=live | archive-url=https://ghostarchive.org/archive/20220105/https://elements.science/about-us/principle-investigators/| archive-date=2022-01-05|access-date=2022-01-05|website=ELEMENTS|language=en-US}}{{cbignore}} Her model predicted that the dynamics and viscosity of the plasma depends on the initial state and any quantum fluctuations.{{Cite web|date=2018-05-30|title=Young physicist Hannah Petersen receives renowned award in Venice|url=https://aktuelles.uni-frankfurt.de/englisch/young-physicist-hannah-petersen-receives-renowned-award-in-venice/|access-date=2022-01-05|website=Aktuelles aus der Goethe-Universität Frankfurt|language=de-DE}}

In 2011, Elfner was appointed a visiting professor at Duke University where she was based in the quantum chromodynamics group.{{Cite web|title=Dr. Hannah Petersen Appointed as Visiting Assistant Professor|url=https://physics.duke.edu/news/dr-hannah-petersen-appointed-visiting-assistant-professor|access-date=2022-01-05|website=Department of Physics|date=15 July 2011 |language=en}} She decided to return to Germany because of the creation of the accelerator FAIR (Facility for Antiproton and Ion Research). She was appointed a Helmholtz Young Investigator in 2012, and a research fellow at the Frankfurt Institute for Advanced Studies the following year.{{Cite web|title=Elfner (Petersen) - Detail / FIAS|url=https://www.fias.science/de/fellows/detail/elfner-petersen-hannah/| url-status=live | archive-url=https://ghostarchive.org/archive/20220105/https://www.fias.science/de/fellows/detail/elfner-petersen-hannah/| archive-date=2022-01-05|access-date=2022-01-05|website=www.fias.science}}{{cbignore}} She was one of the youngest researchers to ever be appointed professor in Germany.

Elfner was made Head of Simulations at the Helmholtz Centre for Heavy Ion Research in 2018.{{cn|date=January 2022}}
