SUMMARY:Science Day 2025 - Physics offerings
DESCRIPTION:The Department of Physics will be represented on Science Day on Saturday, May 24, 2025 with various offers:\nPhysics or magic?Dr. Wolf WölfelDr. Wolf Wölfel introduces children and adults to the world of physics with numerous demonstrations and experiments. What is a spinning top? How many balloons fit into a very cold pot? With impressive experiments, the exciting stage show takes you through the amazing world of natural phenomena - and guarantees a large portion of fun!4 p.m. in V 53.01\nAward ceremony of the mathematics and physics student competition - 1 p.m. in Faculty Hall 8.122\nPhysics research up close\nin the foyer Pfaffenwaldring 53\nHow to program a quantum computerInstitute for Theoretical Physics IIIQuantum computers have the potential to solve certain tasks many times faster than classical computers. However, building a quantum computer is not easy. In the laboratories of the 5th Institute of Physics, we are developing a prototype that uses individual atoms as quantum bits. But how do you actually program a quantum computer? To find out, we have developed an interactive simulator for quantum circuits at the Institute of Theoretical Physics III, which you can try out for yourself at our stand. If you've always wanted to know what Schrödinger's cat and Einstein's spooky telecontrol are really all about, you've come to the right place.\nInteractive simulationsInstitute for Computational PhysicsToday, computer simulations are an indispensable tool for understanding physical phenomena. The areas of application extend across all orders of magnitude, from atoms and molecules to galaxies. The scientists at the Institute of Computational Physics will show you how the behaviour of individual molecules, liquids and other materials can be visualized and understood using computer simulations. Using various examples such as molecular billiards, we will demonstrate the influence of intuitively familiar concepts such as temperature and pressure at the smallest level. \nThe future of secure communication - laser light and quantum cryptography Institute for Semiconductor Optics and Functional Interfaces (IHFG)In recent decades, research into semiconductor nanostructures and quantum dots has ushered in a new era in technology. These tiny structures, which are often only a few nanometers in size, have extraordinary properties that do not exist in the classical world. Lasers based on these nanostructures not only open up new possibilities in sensor technology and data transmission, but also in quantum information technology. Of particular interest are semiconductor quantum dots, which can be used to generate individual “light particles”, photons, in a particularly precise and controlled manner. We will show you how these photons and the principles of quantum physics can be used to transmit, store and check data with absolute security.\nSchrödinger's catInstitute for Functional Matter and Quantum TechnologiesSchrödinger's cat is probably one of the most unusual concepts in quantum mechanics. We take up the concept and try to make it understandable and comprehensible. Furthermore, we show our experimental efforts to realize extended macroscopic quantum superposition states that can be as large as the smallest living organism.\nHands-on physics experiments for young and oldInstitute of Physics and its DidacticsThe “Physics and its Didactics” department opens its doors and provides visitors of all ages with a variety of experiments to try out. Experiments from numerous disciplines of physics can be tried out. We are also available to answer questions about physics or studying.\nSuperconductivity and terahertz1st Institute of PhysicsFundamental research in physics plays a major role. We present how novel superconductors can be characterized using terahertz spectroscopy. These novel superconductors have great potential for use in modern quantum technologies and provide information about the nature of superconductivity itself.\nHistorical experiment on quantum mechanics: The electron double-slit experiment1st Institute of PhysicsIn classical optics, YOUNG's double-slit experiment is always cited as proof of the wave property of light. Claus Jönsson carried out a corresponding experiment with electrons in Tübingen in 1957 to prove the wave properties of particles. This was later voted the “most beautiful experiment of all time”. We use a replica to present details and the underlying physics. \nCenter for Integrated Quantum Science and Technology (IQST)The Center for Integrated Quantum Science and Technology (IQST) was founded in 2014 as one of the first centers worldwide dedicated to the development of innovative technologies from fundamental quantum physics. The key to achieving this goal is to harness, expand and support synergies between the fields of science and engineering. As IQST enters its second decade, quantum technologies are becoming available for applications in new fields. For us, this means continuing to expand our mission, exploring new and unknown frontiers, addressing societal challenges, meeting the needs of an emerging quantum technology ecosystem, and promoting quantum science and technology in a society that is increasingly aware of the potential of quantum technologies.Presentations:- Touching individual atoms? Scanning tunneling microscopes are used to build the smallest quantum systems atom by atom.- Super small, super fast and superconducting: Plasmonic detectors for light quanta- A Qunatum sensor for exploring quantum spin properties- The smallest Kandinsky in the world\nScientific funding from the European Union: Large-scale equipment funding through ERDF Institute for Functional Matter and Quantum Technologies & 4th Institute of PhysicsWe present three ERDF-funded large-scale research devices and explain their applications with our own exhibitions and examples.- An atomic layer coating system allows the conformal coating of surfaces with dense and closed dielectric and metallic films of precisely controllable thickness. The individual monolayers of the material are grown on the sample via gaseous starting substances.- A scanning electron microscope is used for high-resolution and material-specific characterization of and is of great importance in nanotechnology.- A quantum excitation microscope with which individual molecules and atoms are imaged and tested for their potential as atomically small qubits.\nStudying physics - a lecture as part of the Bachelor Info Day2 p.m. in V 47.02
