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.

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.

Elias Pescoller, BSc

Elias is working on the time-dependent reduced density matrix (TD2RDM) method as part of his Master's thesis. He found a new reconstruction functional for the three-particle reduced density matrix based on the maximum entropy principle. He also significantly improved our purification scheme of reduced density matrices.

Marie Eder, BSc

As part of her project work, Marie studies whether our reduced density matrix methods can also be applied to efficiently calculate many-body ground states. She masters python for all the complex systems she has so far investigated.

Florian Grüner

Florian recently started his Bachelor thesis in the group. He will be working on an optimized version of our TD2RDM lattice code for applications on a variety of 2D systems.
