On the unusual behaviour of Cooper pairs: quantum phase transition in Josephson contact

22.04.2020: Superconducting circuits are complex quantum systems consisting of many components. They are needed, for example, to develop quantum computers. The problem: disturbing influences can never be completely avoided and genuine quantum properties are then destroyed. Quantum physicists then speak of "localizing" the very fragile "delocalized" quantum states. A team of researchers from the National Research Centre CEA Saclay (Paris) and the Universities of Ulm and Freiburg has now investigated this quantum phase transition in a superconducting circuit ...more

Alliance of top researchers - Six million euros for competence network on quantum technology

17.03.2020: Quantum technology is one of the most important key technologies of the 21st century. Leading research establishments and institutes have joined together to form a state-wide association: The "Quantum Technology - Baden-Württemberg" (QTBW) competence network is intended to give the location greater visibility and weight in international competition. ...mehr


New high-performance computer officially opened. JUSTUS 2 enables complex simulations in chemistry and quantum physics

06.03.2020: The University of Ulm has a new high-performance computer: with a theoretical performance of 2 petaflops, the 4.4 million euro supercomputer JUSTUS 2 sets new standards. On Friday, 6th March, Ministerial Director Ulrich Steinbach (State Ministry of Science, Research and Arts) and the President of Ulm University, Professor Michael Weber, among others, pressed the symbolic start button. Representatives of the cooperation partner NEC Deutschland GmbH also attended the official opening ceremony. ...more


Walking with atoms - Chemical bond making and breaking recorded in action

20.01.2020:  Scientists have for the first time captured and filmed atoms bonding, using advanced microscopy methods they captured a moment of breaking a chemical bond, around half a million times smaller than the width of a human hair. Ever since it was proposed that atoms are building blocks of the world, scientists have been trying to understand how and why they bond to each other. Be it a molecule (which is a group of atoms joined together in a particular fashion), or a block of material or a whole living organism, ultimately, everything is controlled by the way atoms bond, and the way bonds break. ...more


Second Synergy Grant over 9.4 million euros for Ulm physicists! Unravelling cell metabolism with the help of MRI and diamond sensors

11.10.2019:  The physics professors Martin Plenio and Fedor Jelezko from Ulm have yet again landed a major coup: they have obtained another rare ERC Synergy Grant, the second time in a row since 2012. The third member of the new HyperQ project is Professor Jan Ardenkjær-Larsen from the Technical University of Denmark. Their goal is to revolutionise nuclear spin applications using quantum technology, from the well-known MRI scanner in hospitals to tiny sensors that can be used to study metabolic processes in living organisms. ...more


Einstein is tested: a quantum-mechanical twin paradox

07.10.2019: Albert Einstein is regarded as one of the founding fathers of modern physics, in particular his general and special theory of relativity and his fundamental contributions to quantum mechanics continue to have significance to this day. Physicists from Ulm and Hanover are investigating the intersections of both theories and have chosen the famous twin paradox derived from the theory of relativity. In the scientific journal „Science Advances“ , the researchers published the theoretical preliminary work for an experiment ...more

 


Reinhart Koselleck project: 1.5 million euros for "risky research" - revolutionizing nuclear spin applications with quantum technology

19.06.2019:  So far, applications of nuclear magnetic resonance such as medical MRT imaging or NMR spectroscopy are not sensitive enough to allow high-precision measurements. But now Professor Martin Plenio wants to pave the way for nuclear magnetic resonance at the micro and nanoscale with the help of quantum technology. For this innovative but also highly challenging research project, the German Research Foundation (DFG) has granted the theoretical physicist a Reinhart Koselleck project and over 1.5 million euros for five years.  ...more


Lithium atoms on the move - SALVE provides sensational insights into mini batteries

27.11.2018: You can call it simply a sensation, what has been achieved by scientists from Stuttgart, Ulm and Dresden. Using the Sub-Angstrom Low-Voltage Electron microscope (SALVE), they were able to show in atomic resolution how lithium ions behave during electrochemical loading and unloading processes. They have thus demonstrated how reversible lithium absorption takes place in a nano-cell that consists of only one double layer of graphene. These results, which are highly relevant for battery research, were recently published in the journal Nature   ...more
