*** ERC Advanced Grant *** Congratulations to Thomas Udem, research group leader in the MPQ laser spectroscopy division, who has successfully acquired an ERC Advanced Grant with a volume of €2.5 million for his project H-SPECTRE. He will use these highly remunerated funds to further advance precision experiments on the spectroscopy of atomic hydrogen and deuterium to uncover new physics beyond the standard model. Two experiments for the precision measurement of certain transition frequencies in hydrogen are already in place at the MPQ. Another experiment, in which researchers seek to develop an optical hydrogen clock, is currently being set up.  https://lnkd.in/d7Xz5Gmy

New addition to the #skQCI team This week we are pleased to welcome our new young researcher from France, Younes Benamara. Younes’ background includes simulation work for the studying the morphology of 2D structures and statistical study of systems using different machine learning methods. Supervised by Dr. Djeylan Aktas, his thesis “Experimental quantum photonics for quantum communications” will aim to leverage nonlinear optics to build and exploit photon pair sources for quantum communication . His research will focus on interfacing photonic layers with classical network and post-processing data to create a #QKD prototype to be deployed in an academic Slovak test-bed. This will pave the way to many future new potential research like the possibility to investigate new quantum communication protocols which also rely on the distribution of entanglement. His #PhD is fully covered by European grant #EuroQCI DIGITAL. #quantumcommunication #eduQUTE

Congratulations to our alumni Arthur Christianen for his recent accomplishments - successful PhD defense, #MCQST PhD Award, and a new position as a postdoc at ETH Zürich! After his #MCQST2024 award talk, we asked Arthur about his time in Munich, advice for future graduate students, and research plans. *With what memories do you leave your group and the community in Munich, and what would you advise someone who just joined it recently?* I had a great time during my PhD at the Max Planck Institute of Quantum Optics, where I had a very friendly culture in our group, with weekly homemade cakes, nice group outings (e.g. to Zugspitze), regular board games and karaoke sessions. There I also got many opportunities to develop myself as an independent scientist and establish international connections. I also benefited from all the great activities that IMPRS-QST and MCQST organized, both on a scientific and a personal level. I met many interesting people in the Munich quantum community and beyond and could develop essential soft skills to further my career. I would advise new people joining the community to definitely make use of these excellent opportunities to meet new people and to immerse yourself also in the research beyond your own field. In such an excellent scientific environment, there are endless possibilities, especially if you have an open mind and take an active stance. *Looking ahead, what are your long-term goals and aspirations in the field of quantum research, and how do you envision making an impact in this rapidly evolving field?* The area of quantum technology I am personally most interested in is quantum simulation, in particular in the setting of ultracold gases. Having access to very controllable systems to simulate complex problems that are hard to understand theoretically can really help to answer important open questions in physics.   I think it is important that the knowledge and understanding we gain with these systems is also exchanged with other fields such as condensed matter physics and chemistry. I have always enjoyed working in a multidisciplinary setting, and reinforcing the connections and transferring ideas between these different scientific disciplines is therefore one of my personal research and career goals. My work focuses on bridging the gap between few- and many-body physics. Already on the level of three quantum particles with strong interactions interesting quantum effects appear. I am interested in how such few-body effects manifest themselves in a medium, and how they lead to the emergence of fascinating new phenomena. In my PhD, I have mostly focused on the platform of ultracold gases, but in the next step of my career, I am expanding my scope to other systems, such as two-dimensional semiconductors.

An international team of researchers from Leibniz Universität Hannover (Germany) and the University of Strathclyde in Glasgow (United Kingdom) has disproved a previously held assumption about the impact of #multiphoton components in #interference effects of thermal fields (e.g. sunlight) and parametric single #photons (generated in non-linear crystals). The finding offers new starting points for research into photonic #quantum information systems. "We experimentally proved that the interference effect between thermal light and parametric single photons also leads to quantum interference with the background field. For this reason, the background cannot simply be neglected and subtracted from calculations, as has been the case up to now," says Prof. Dr. Michael Kues, Head of the Institute of Photonics and member of the Board of the PhoenixD Cluster of Excellence at Leibniz University Hannover.

Dear colleagues, on behalf of organizers, I would like to invite you to attend to the minicolloquium “Collective and nonlinear phenomena in confined quantum systems” (MC8) within the 31th General Conference of the Condensed Matter Division of the European Physical Society CMD31, which will be held from 2 to 6 September 2024 in Braga, Portugal. The topics that will be discussed include quantum gases, particularly ultracold atoms, with a special emphasis on collective excitations, solitons, and vortices. The colloquium will bring together both theorists and experimentalists in condensed matter physics. Quantum gases are a fascinating area of research, and ultracold atoms have been at the forefront of this field for several years. For example, the observation of Bose-Einstein condensation in ultracold atomic gases has opened up new avenues for research in quantum mechanics. The study of collective response, both linear and nonlinear, in these systems has led to a lot of interesting and important discoveries. In addition to the aforesaid topics, we will also explore other areas of research that are related to confined quantum systems. These may include, but are not limited to, quantum computing, quantum information theory, and quantum optics. We hope that this minicolloquium will provide a platform for researchers to share their latest findings and ideas, and to foster new collaborations. We look forward to welcoming both theorists and experimentalists in condensed matter physics to this exciting event. This minicolloquium continues and expands the scope of the successful minicolloquia “Collective Effects & Non-Equilibrium Phenomena in Quantum Gases and Superconductors” held at CMD29 – Manchester in 2022 and “Quantum gases as analogues of condensed matter systems” held at CMD30 – Milano in 2023. Please visit the CMD31 website for more details: https://lnkd.in/ePcgGfhm and the webpage of the mini-colloquia: https://lnkd.in/esH22QpH The abstract submission is now open at the CMD31 website: https://lnkd.in/eMCKGxVY The abstract submission deadline is 15 April 2024.

𝐌𝐞𝐞𝐭 𝐨𝐮𝐫 𝐦𝐞𝐦𝐛𝐞𝐫𝐬: 𝐂𝐡𝐫𝐢𝐬𝐭𝐢𝐚𝐧 𝐆𝐮𝐭𝐭 "After several research positions both in Germany and the USA I became a Professor of Solid State Physics at the Universität Siegen in 2013. My research is focused on exploring the dynamics of condensed matter on the atomic and molecular scale. We develop and use advanced techniques like X-ray photon correlation spectroscopy (XPCS) to study how materials behave and evolve under different conditions. Advancing the boundaries of X-ray science through the development of new methods and instrumentation is a key focus for us. We are also leveraging the power of neural networks and other machine learning methods to analyze large amount of complex X-ray data. Currently, I am also the Chair of the Committee for Research with Synchrotron Radiation (KFS) representing 4000 users in Germany vis-a-vis politics, funding agencies and large-scale-facilities. In the KFS, we are, for example, helping to shape various funding schemes and represent the user community in the upgrade process of the current sources of synchrotron radiation so that we can maintain the leading position of German synchrotron research in an international competitive environment. In this respect it is currently an exciting time for X-ray science, and we’re constantly looking for innovative ways to expand the capabilities of our research." #UniSiegen #XPCS #XRayScience #KFS #Research #Physics #ChiralSystems #DynamicsofProteins #Science

Quantum Light Droplets Unveil New Realms of Macroscopic Complexity Scientists have advanced the field by stabilizing exciton-polaritons in semiconductor photonic gratings, achieving long-lived and optically configurable quantum fluids suitable for complex system simulations. Researchers from CNR Nanotec in Lecce and the Faculty of Physics at the University of Warsaw used a new generation of semiconductor photonic gratings to optically tailor complexes of quantum droplets of light that became bound together into macroscopic coherent states. The research underpins a new method to simulate and explore interactions between artificial atoms in a highly reconfigurable manner, using optics. The results have been published in the prestigious journal Nature Physics. Read more https://lnkd.in/d7hT9hs4

Biological nature of the universe confirmed? A small - back to the future - or future to the back - Paradox --> Covid-19 Covid-Breakthrough Mechanisms Decoded by Science? A recent paper of extraordinary work! ( Very good stuff - nobody has done it so far - officially?). https://lnkd.in/dB7peRfw However when I look at my fractal mechanisms and simple basics - this is exactly what I find and with confirmation by ancient notifications. How nature copies and processes information in general - not only in the human body but also in the weather systems and in whole galaxies. Here is my fractals simulation video: https://lnkd.in/dm-2NxXH It looks like we can simulate almost everything we need in science optically (holographically) and then calibrate the numerical methods to it. This breakthrough discovery reported in nature and my fractal simulation confirms partially (initially) that my statements might be right - the whole universe might work like one giant biological body and on biological principles. This would implicate: Constructing big megalithic neuronal structures shall be sufficient to read biological messages from space. And perhaps deliver galactic electric impulses and huge holographic energy types to everyone (which is like "peanut" for the whole comic universe body? We can simulate all of this down to the fractal detail we need thanks to my methodology. Are there enough paradoxes and coincidences? Or we shall Change something in our understanding of the universe? This would explain that naturally -biologically some time-space regions are expanding and contracting - the big cosmological and astronomical crisis would be solved in one sentence. The mystery of humanity - biology shows that in our body there are plenty of small antibodies that behave like small humans inside of us. Example here (amazing) done a few years ago! : https://lnkd.in/dgKEGnqe I do not want to be a fortune teller again: It is just an -inconvenient paradigm and orientation shift that might be required soon for the whole of physics and chemistry and thermodynamics - on the giving right to complicated biological mechanisms on a large scale. Instead of reading new images from satellites - we might simply cause some biological large-scale actions - that will force the body to react and cool down our planet. "By placing too many military and spy satellites and space dust " - perhaps we are introducing a cancer-like behavior into our body of universe? Do we observe the right singals in proper way ? Perhaps ancient people did it the right way with regard to nature's biology and rhythms. Perhaps we are looking for the wrong type of signals in space - and preventing other valuable signals from being transmitted to the Earth and from the Earth outside? Have we ever thought like that?
