A „Quantum“ Insight

Quantum physics today is to be found in almost every corner of our everyday lives. But how well is it understood in society? The new special exhibition ‘Light and Matter’ at the Deutsches Museum starting today illuminates quantum optical phenomena and turns them into tangible matter. With numerous objects, scenoramas and many hands-on stations, the exhibition shows how the understanding of the light matter interaction has evolved over the last century, and offers an insight into current research and future applications. more

An experimental team from the Max Planck Institute for Quantum Optics and the Ludwig Maximilian University Munich successfully observed and manipulated the peculiar states emerging at topological boundaries, so-called edge modes. Key to the researchers’ breakthrough was the level of unprecedented control over the experimental parameters, which previously rendered the observation of these edge-modes elusive. The results are featured in Nature Physics. more

The experimental physicist receives the distinction for her pioneering work in molecular spectroscopy with interfering frequency combs. Named in honour of the eponymous scientist’s contributions to spectroscopy and metrology, the William F. Meggers Award was established in 1970 by Optica. Nathalie Picqué was presented with the award on 7 May 2024 at the CLEO Conference in Charlotte (NC), USA. more

Oriana Diessel completed her doctorate in Richard Schmidt's independent research group. Her theoretical work focusses on two special features of many-body systems: so-called "polarons" and previously unknown phase transitions in light-matter systems. In her work, Oriana Diessel developed models to theoretically describe the two phenomena, thereby providing a further building block for our understanding of quantum many-body theory. more

Being elected as a member of the National Academy of Sciences is regarded as one of the most distinguished honours a scientist can receive. While the majority of members hold U.S. citizenship, up to 30 international members are elected annually. NAS members are “charged with providing independent, objective advice on matters related to science and technology”. more

Physicists at MPQ have now succeeded for the first time in creating a ring-shaped and a tree-shaped graph state in an experiment for complex entanglement structures. This is a major breakthrough for the development of quantum computers or the quantum internet. In a future quantum internet, light quanta could thereby be entangled to form a quantum message that is much more stable against losses. more

On the 1st of May 2024, a new independent research group “ultracold lithium-rubidium molecules” has started at MPQ. Dr. Xinyu Luo, research group leader in the quantum many body division, has been awarded the renowned ERC Consolidator Grant of two million Euros. With the funding, the researchers take on one of the central challenges of modern physics today – the creation and investigation of unconventional superfluids. more

Frozen yoghurt, roses and lasers - Girls' Day 2024 at the MPQ

A packed programme awaited this year's Girls' Day participants. In addition to talks by Dr Silke Stähler-Schöpf, head of the school laboratory, and PhD student Maya Büki, the day's main theme was "try it yourself". In the Photonlab school laboratory, the participants had a go at the various experiments and learnt about physical phenomena in a fun way - in particular, how lasers work, which play an important role in the institute's research. more

Theorists in the research group of Mari Carmen Bañuls at MPQ have come one step closer to understanding the evolution of quantum many body systems over time. In their work, recently published in the specialized journal Physical Review Letters, they formulated an algorithm to simulate the dynamics of quantum systems consisting of many particles out of equilibrium – a notoriously difficult task. more

Thomas Udem wins ERC Advanced Grant of €2.5 million

Thomas Udem, group leader at the MPQ, has successfully acquired an ERC Advanced Grant with a volume of 2.5 million euros. He will use the funds to his project H-SPECTR to further advance precision experiments on the spectroscopy of atomic hydrogen and deuterium and thus gradually uncover new physics beyond the standard model. more

Dr Bañuls, group leader in the Theory Department at MPQ, has earned special recognition in her many years of excellent research of complex quantum systems, and is now starting her own W2 research group. Her research focuses on the development and application of tensor network methods for the numerical simulation of quantum many-body systems and quantum dynamic phenomena beyond equilibrium. more

Nathalie Picqué, a pioneer in dual-comb spectroscopy, has commenced a director position at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin, where she will establish the Division of Precision Physics. In addition, the researcher has accepted a tenured professorship at Humboldt University. more
