Theoretical Physics III: Correlated quantum matter

In our research we are interested in the dynamics of correlated quantum matter at the interface between quantum many-body theory, nonequilibrium physics, quantum information science, and machine learning. The research covers the development of a theory of dynamical quantum phase transitions, the dynamics in lattice gauge theories, the exploration of machine learning techniques as a new toolbox in quantum many-body theory, many-body localization in interacting strongly disordered systems, or entanglement in correlated quantum matter.

Machine learning solves complex quantum problems

Due to a new method, artificial neural networks, as used in machine learning, will be able to be trained quicker so as to be able to solve complex problems in quantum mechanics. For example, previously unexplained properties of a special state of matter, the quantum spin liquid, can be calculated, something that has not been possible with any previous method to date. This has been made possible by a new optimisation method developed by the Institute of Physics.

Leading quantum mechanical research

The Centre for Electronic Correlations and Magnetism (EKM) was established in the early 1990s. Since then, it has become a top research institute in the field of quantum mechanics. The meeting of the scientific advisory board of the EKM in Augsburg, composed of leading experts in the field, confirms this.

Fundamentale Frage der Quantenphysik

Ein internationales Team von Physikern unter Beteiligung der Universität hat erstmals eine wichtige theoretische Vorhersage der Quantenphysik bestätigt. Die Berechnungen dazu sind so komplex, dass sie bislang selbst Supercomputer überforderten. Den Forschern gelang es jedoch, sie mit Methoden aus dem Bereich der künstlichen Intelligenz deutlich zu vereinfachen.

Paper: Reinforcement Learning for Digital Quantum Simulation

Digital quantum simulation on quantum computers provides the potential to simulate the unitary evolution of any many-body Hamiltonian with bounded spectrum by discretizing the time evolution operator through a sequence of elementary quantum gates. A fundamental challenge in this context originates from experimental imperfections, which critically limits the number of attainable gates...
