This is an exciting opportunity to learn and contribute to state of the art research and applications in quantum computing, a rapidly expanding field of modern quantum physics. Corresponding research takes place in the framework of the BMBF project RYMAX (supporting programme quantum technolgies: from the foundations to the market) and offers many possibilities to contribute to e.g. the development of hybrid classical quantum algorithms, the controlled engineering of many-body Rydberg states and the generation of entanglement as a resource for quantum computation. In case you are interested please contact us to get further information and discuss possible thesis projects.</p>

The network consists of eleven nodes including prestigious partners from Paris, Strasbourg, Heidelberg, Bielefeld, Colorado, Haifa, Vienna, London and Wuhan. The breadth of the scientific applications ranges from heterogeneous catalysis, collisional physics, photochemistry and spectroscopy to laser-controlled quantum dynamics and ultracold quantum gases. The objectives of the network is the development of novel methodologies and their widespread applications as well as the training of young researchers in the framework of dedicated events, such as schools and workshops. The concerted action of many researchers under a common roof represents a unique opportunity to advance our knowledge of quantum dynamical processes. It will push the frontiers of this highly vibrant field finally allowing for the design of quantum matter with novel functionalities.</p>NAGR-fakmin-19414393-production2019-09-17T22:00:00ZLenz-Ising Award for Dr. Simeon Mistakidis<p>Dr. Simeon Mistakidis has been firstly awarded the Lenz-Ising Prize for outstanding junior scientists by the Department of Physics at the University of Hamburg. This Prize aims at aiding financially researchers at the early stages of their scientific career. He accomplished his PhD thesis at the center for optical quantum technologies of the University of Hamburg addressing the correlated nonequilibrium quantum dynamics of few and many-body ultracold atomic systems and mixtures thereof. His postdoctoral research activities will focus on the microscopic mechanisms that lead to polaron formation unveiling their dynamical dressing, correlation induced interactions, orthogonality catastrophe events and entanglement based processes. Aspects on the aforementioned topic have been recently published in Physical Review Letters (Phys. Rev. Lett. 122, 183001 (2019)).</p>NAGR-fakmin-18307444-production2018-06-11T22:00:00ZPeter Schmelcher elected into Topical Group of American Physical Society<img width="293" height="165" style="float:left" src="https://assets.rrz.uni-hamburg.de/instance_assets/fakmin/19267416/peter-schmelcher-733x414-93e809538b42520407942b254d5770137fb79aa5.jpg" /><p>Peter Schmelcher, from the center for optical quantum technologies of the University of Hamburg, has been elected by the American Physical Society into the executive committee of the Topical Group on Few-Body Systems and Multiparticle Dynamics. The mission of this group is to advocate, promote, and advance research on few-body systems. This APS Group is an umbrella organization of atomic, molecular, nuclear, particle, and mathematical physicists,<br>as well as quantum chemists, who are interested in the dynamics of fundamental building blocks of complex matter. Such systems have relatively few degrees of freedom at some energy scale, and their study provides significant information about the dynamics of systems in a given area of physics,as well as identifies features common to systems in a variety of different sub-disciplines. Because of the interdisciplinarity of the group, many of the sessions at APS meetings are held jointly with other Groups and Divisions and feature specific themes from different fields.</p><p>Photo: SFB925</p>NAGR-fakmin-18307467-production2017-01-17T23:00:00ZCelebrated Optical Frequency Comb Goes Vibrational<p>For electromagnetic radiation the celebrated frequency comb has brought the precision of atomic clocks that operate in the microwave region to the optical part of the spectrum.<br><br>Very recently a work published in Phys.Rev.Lett. 118, 033903 (2017) has demonstrated that phononic frequency combs can be generated via intrinsic three-wave mixing.<br>A micromechanical device generates a series of precise, equally spaced vibration frequencies, analogous to the light of the optical frequency comb.<br><br>This work is an experimental realization and implementation of our theoretical work on phononic frequency combs through nonlinear resonances in Phys. Rev. Lett. 112, 075505 (2014).<br>In the underlying process, a set of phonon modes is simultaneously excited by the external driving which yields frequency combs with an array of discrete and equidistant spectral lines of each nonlinearly excited phonon mode. Frequency combs through nonlinear resonance of different orders have been investigated, and in particular the possibility of correlation tailoring in higher-order cases is revealed. These results can be applied in various nonlinear acoustic processes, such as phonon harvesting, and can also be generalized to other nonlinear systems.<br><br>See Physics10,4</p>NAGR-fakmin-18307478-production2015-12-14T23:00:00ZOtto-Stern award for Johannes Knörzer<p>Johannes Knörzer has been awarded the Otto-Stern Award for the best master thesis of the summer term 2015 of the physics department of the University of Hamburg. The prize-giving will take place during the Christmas party of the physics department on 16 December 2015. His thesis aimed at unraveling the possibilities for studying highly correlated many-body excitation dynamics around segmented carbon nanotubes. The resulting edge-localized electronic excitations lead to series of Rydberg states which are attracted to the metallic or semiconducting nanotube by their image charges. This work has recently been published in Journal of Chemical Physics (JCP 143, 204309 (2015)).</p>NAGR-fakmin-18307489-production2015-12-13T23:00:00ZFriedrich Wilhelm Bessel award for Prof. Kevrekidis<p>Professor Panagiotis Kevrekidis (University of Amherst, Massachusetts) has been awarded the Friedrich Wilhelm Bessel Research Award of the Alexander von Humboldt foundation for his outstanding research in nonlinear science including optics, ultracold quantum matter and granular materials. Within the award he will spend an extended research visit in 2016 on a long-term research project with Professor Peter Schmelcher at the Center for Optical Quantum Technologies (ZOQ) of the Department of Physics. The aim of the investigations is to develop a deep understanding of the nonlinear excitations occuring in Bose-Einstein condensates as applied to the dynamical processing of macroscopic matter waves in matter wave optics. Symbiotic excitations of mixtures of quantum gases are a research focus at ZOQ and the expertise<br>of Professor Kevrekidis will be of great value for the collaborations in order to push the frontiers of this highly topical research area. During his visit in August and September 2016 Professor Kevrekidis would be happy to closely interact with many colleagues from theoretical and experimental physics.</p>
