About me
I am a theoretical physicist and currently a Marie Skłodowska-Curie Postdoctoral Fellow. I am hosted by the Geballe Laboratory for Advanced Materials at Stanford University, USA, and the Institute of Theoretical Physics at Leibniz Universität Hannover, Germany. Prior to that I was a postdoc in the Department of Physics and Astronomy at University College London, UK. I obtained my PhD from the University of Osnabrück, Germany.
Academic positions and Education
Marie Skłodowska-Curie Postdoctoral Fellow
2022 -
Stanford University, USA
Host: Vedika Khemani
Leibniz Universität Hannover, Germany
Host: Tobias J. Osborne
Funding
I was awarded a MSCA Postdoctoral Fellowship by the European Commission for my project MaBoQuaCo "Quantum Many-Body Dynamics and Noisy Intermediate-Scale Quantum Computers: Interconnections, Near-Term Applications, and Novel Simulation Schemes". The goal of the project is to explore fundamental aspects of nonequilibrium many-body quantum physics at the intersection of condensed matter physics, quantum statistical mechanics, and quantum information.
The project has a total budget of approximately 240.000€, giving me the opportunity to conduct research at Stanford University, USA, during the first phase, as well as at Leibniz Universität Hannover, Germany, during the second phase.
I started to write a blog, where I want to report on the progress of my project, write about some general aspects of quantum physics, and share some thoughts about the life as a postdoc. If you are interested, click here.
Research
I am interested in various aspects of quantum many-body physics:
- Far-from-equilibrium dynamics and thermalization
- Eigenstate thermalization hypothesis
- Many-body localization
- Numerical approaches to quantum many-body dynamics
- Emergence of hydrodynamic transport in many-body systems
- Quantum scars and Hilbert-space fragmentation
- Applications of NISQ devices in quantum many-body physics
- Quantum typicality
