Autumn School on Correlated Electrons: Simulating Correlations with Computers
20 sep 2021 - 24 sep 2021 • Jülich, Allemagne
Résumé:
The combinatorial growth of the Hilbert space makes the many-electron problem a grand challenge. Progress relies on the development of non-perturbative methods, based on either wavefunctions or self energies. This made, in recent years, calculations for strongly-correlated materials a reality. These simulations draw their power from three sources: theoretical advances, algorithmic developments and the raw power of massively parallel supercomputers. Turning to quantum hardware could give quantum materials science the ultimate boost. Before quantum parallelism can be exploited, however, many questions, algorithmic and engineering, need to be addressed. The school will provide students with an overview of the state-of-the-art of many-body simulations and the promises of quantum computers. After introducing the basic modeling techniques and the concept of entanglement in correlated states, lectures will turn to methods that do not rely on wavefunctions, comparing density functional theory, the GW method and dynamical mean-field theory. Advanced lectures will broaden the discussion, addressing topics from the Luttinger-Ward functional to non-equilibrium Green functions. As a glimpse of future possibilities, the basics of quantum computing and its possible uses in materials simulations will be explained. The goal of the school is to introduce advanced graduate students and up to the full range of modern approaches for the realistic simulations of strongly correlated materials with computers.

Quantum Optics Conference 2021
26 oct 2021 • Haar - online, Allemagne
Organisateur:
attocube systems
Résumé:
Quantum and magneto optics are amongst the largest and most active fields of research in physics. Today, heavily funded quantum iniatitives around the world are seeking to drive forward the quantum revolution through quantum computing, quantum sensing and quantum communication. For more than two decades, attocube has been an active and integral part of this scientific community, with co-founder Prof. Karraï working amongst the pioneers in the fields of quantum dots, cavity optics, and confocal microscopy at cryogenic temperatures. Offering a broad portfolio of cryogenic research equpipment, attocube established a broad network of customers and scientists around the world, and we are proud to present talks by some of the foremost authorities in the field during our online conference.

Join the free-of-charge event to gain insights on recent advances in research and applications on single photon sources, 2D materials and 2D magnets, NV and other color centers, quantum sensing in high pressure physics and cavity quantum optics. The conference is divided in three parts. Register below for two sessions of scientific presentations (followed by Q&A sessions), as well as for the panel discussion.
