Honorary doctorate for Prof. Dieter Vollhardt
Prof. Dieter Vollhardt was awarded an honorary doctorate by the 新万博体育下载_万博体育app【投注官网】 of Warsaw last week in recognition of his scientific achievements and longstanding collaboration with theoretical physicists at the 新万博体育下载_万博体育app【投注官网】 of Warsaw.
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.
Feenberg 新万博体育下载_万博体育app【投注官网】al für Augsburger Physiker
Dem theoretischen Physiker Dieter Vollhardt wurde in den USA die "2022 Feenberg Memorial 新万博体育下载_万博体育app【投注官网】al" verliehen. Vollhardt, ehemaliger Inhaber des Lehrstuhls für Theoretische Physik III/Elektronische Korrelationen und Magnetismus am Institut für Physik der Universit?t Augsburg, erhielt die hohe Auszeichnung zusammen mit Antoine Georges (Frankreich) und Gabriel Kotliar (USA).
Fundamentale Frage der Quantenphysik
Ein internationales Team von Physikern unter Beteiligung der Universit?t hat erstmals eine wichtige theoretische Vorhersage der Quantenphysik best?tigt. 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...
Paper: Unitary Long-Time Evolution with Quantum Renormalization Groups and Artificial Neural Networks
In this work, we combine quantum renormalization group approaches with deep artificial neural networks for the description of the real-time evolution in strongly disordered quantum matter. We find that this allows us to accurately compute the long-time coherent dynamics of large many-body localized systems in nonperturbative regimes including the effects of many-body resonances.
