Group leader
Assistant Prof. Iva Březinová

Is the head of the group and works on method development for approximate solutions of the time-dependent Schrödinger equation, with broad interests in applications to experimentally realizable driven and non-equilibrium quantum many-body systems. Her group collaborates with researches from Europe, Japan (University of Tokyo), and the USA (CCQ, Flatiron Institute, NYC).

Katharina Buczolich, MSc

As part of her PhD, Katharina studies the dynamics of multi-electron atoms driven by strong laser fields. The atoms she investigates are as large as xenon with its 54 electrons! She uses several multi-electron approaches such as the wavefunctions based MCTDHF, and our newly developed time-dependent two-particle reduced density matrix (TD2RDM) method. She has already unraveled interesting effects of correlations in strong-field and ultrafast processes, and is the expert on our sophisticated multi-electron code.

Susmita Jana, MSc

For her PhD, Susmita Jana is working on the dynamics of multi-electron atoms in strong laser fields. In particular, she is investigating correlation effects in strong field driving that have remained elusive due to their numerical complexity. One example is the enhanced ionization yield in strong field double ionization.

Elias Pescoller, MSc

As part of his doctoral thesis, Elias is working on the theoretical description of the interaction of high-energy electrons with ions in an ion trap, as used in ion-based quantum computers. The aim is to use quantum metrology approaches and a quantum computer to read the electronic state in an electron microscope more efficiently. His work is part of the collaborative project ‘Quantum-enhanced Electron Microscopy (QCEM)’ under the joint supervision of Dennis Rätzel, opens an external URL in a new window and Philipp Haslinger, opens an external URL in a new window.

Katja Schneeweiss, MSc

For her PhD, Katja is working on time-dependent quantum many-body systems in the context of ultracold atoms. Specifically, we study the quantum correlations that arise when an impurity is embedded in a large environment of interacting quantum particles - something realizable under controlled conditions in experiments with ultracold atoms. To the end, we will ask some fundamental questions about the process of a quantum measurement. Her project is in close collaboration with the theory group of Marcus Huber, opens an external URL in a new window and the experimental group of Hanns-Christoph Nägerl, opens an external URL in a new window.

Marie Eder, BSc

As part of her master's thesis, Marie is working on applying our two-particle reduced density matrix method (TD2RDM) to correlated molecular spectra. In doing so, she is also developing interfaces to other established methods such as CCSD(T) in collaboration with the group of Andreas Grüneis, opens an external URL in a new window.

Florian Grüner

As part of his bachelor's thesis, Florian is developing an optimized version of our TD2RDM grid code for applications on a variety of 2D systems. Meanwhile, he knows more about tensor libraries than most (any?) of us.
