QUANTUM MATTER THEORY GROUP - Key Persons


David Hagenmuller

Job Titles:
  • CNRS Researcher
After a master degree in Orsay (France), I obtained a PhD in theoretical physics at université Paris-Diderot (thesis advisor Cristiano Ciuti) in 2012, where I developed a strong interest in cavity quantum electrodynamics applied to condensed-matter systems. I then moved to the university of Toronto to develop a project about photonic band gap materials in the ultra-strong coupling regime in collaboration with Sajeev John. As of 2015, I have been working in the Quantum Matter Theory Group at the University of Strasbourg as a post-doc, and since 2020 as a permanent CNRS researcher (chargé de recherche). I am still particularly interested in the interface between condensed-matter and cavity-QED, and typically investigate how basic properties such as electronic quantum phases and transport can be modified in the presence of strong light-matter interactions occurring in a cavity-type structure.

David Wellnitz

Job Titles:
  • Student
From 2013 to 2018, I studied physics in Heidelberg. In 2018, I wrote my Master thesis in the group of Professor Weidemüller on the application of network theory to atomic spectra. In November 2018, I have started my PhD in physics in the group of Professor Pupillo in Strasbourg. Here, I am analyzing how methods of quantum optics can influence chemistry. I am particularly interested in the collective dynamics arising due to collective light matter coupling.

Guido Masella

I graduated from the University of Pisa in 2015 focusing my studies on simulations of non-equilibrium dynamics of cold atomic gases. After a short post graduate training at CNR-INO (Italy) working on an experiment involving dipolar quantum Gases of Dysprosium atoms, in February 2017 I started my Ph. D. at University of Strasbourg on the study of "Exotic Phsenomena in Cold Atomic Gases"". My research interests include the study of equilibrium and non-equilibrium phenomena in ultracold atomic gases and in general in systems of interest for condensed matter and atomic physics. I am deeply interested in the computational challenges related to these problems, in the study and in the development of numerical tools and methods capable of tackling efficiently these problems. Keywords: Computational Physics, Many-body Physics, Cold Gases

Guillermo Preisser

Job Titles:
  • Student
Guillermo joined the Quantum Matter Theory group in Strasbourg on February 2020 after graduating from the National Autonomous University of Mexico in 2019. He will work on semi-classical modeling of open quantum technology platforms.

Johannes Schachenmayer

Job Titles:
  • CNRS Researcher
I am a permanent CNRS researcher at CESQ/ISIS and joined the team in Strasbourg in 2016. After my undergraduate studies at the Technical University in Munich (TUM) I moved to Innsbruck (Austria) where I continued with a PhD program in the group of P. Zoller, supervised by A. J. Daley. During my PhD years I moved to the University of Pittsburgh (USA) as a visiting research scholar until graduation in 2012. I stayed in the US, working as a post-doc at JILA (Boulder, USA) in the group of A. M. Rey. My main research interest is the theory of quantum many-body non-equilibrium physics. I'm interested in far-from-equilibrium dynamics in many-body models, which I study by utilizing numerical methods and quantum optics tools [e.g.: matrix product states (MPS)/tensor networks, truncated Wigner approximations (DTWA), quantum trajectories, adiabatic elimination, ...]. Applications of my work are in the fields of (ultra-)cold atom physics and cavity-coupled molecules.

Prof. Guido Pupillo

Job Titles:
  • Secretary
  • Director - Distinguished Full Professor
  • Distinguished Full Professor
Guido Pupillo is Distinguished Full Professor (PRCE) at the University of Strasbourg, Director of the "Laboratory of Quantum Physics" at the Institut de Science et d'Ingénierie Supramoléculaires (ISIS) and of the new "European Center for Quantum Sciences - CESQ" of the University of Strasbourg and CNRS, where he is involved in the development of teaching and research programs in quantum science and technology. He obtained his Master in Physics at the University of Bologna in 2001 and a PhD in Physics in 2005 at the University of Maryland for research conducted at the National Institute of Standards and Technology (with Dr. Carl J. Williams). Until 2011 he was scientist and then senior scientist at the University of Innsbruck and the Austrian Academy of Sciences, where he obtained his Habilitiation in Theoretical Physics (with Prof. P. Zoller). In 2012 he became full professor at the University of Strasbourg (FR). He is Scientific Coordinator of the MSCA COFUND "QUSTEC - Quantum Science and Technologies at the European Campus" and Coordinator of the MSCA ITN "MOQS - Molecular Quantum Simulations". He is recipient of several awards, including the 2012 ERC Starting Grant and the 2013 Guy Ourisson Prize. He is fellow of the Global Young Academy, the Young Academia Europaea. Since 2019 he is fellow of the University of Strasbourg Institute for Advanced Study (USIAS) and Senior Fellow of the Institut Universitaire de France (IUF). His research interests are in atomic, molecular, and optical physics, quantum simulations and quantum computing.

Sven Jandura

Job Titles:
  • Student
I completed a Bachelor's degree in physics and in mathematics at the University of Munich, and a Master's degree in physics at ETH Zurich. During my studies I developed an interest in quantum information processing and quantum technologies. I joined the Quantum Matter Theory group in June 2021 and theoretically investigate quantum gates on Rydberg atoms. In particular, my research is focused on on multi-qubit-gates (three or more qubits) and how to implement them natively on Rydberg hardware without decomposing them into single and two qubit gates.
