Our research combines experiment with theory, employing techniques of atomic physics, quantum optics and optomechanics. A common goal of our activities is to investigate quantum physics in systems of increasing size and complexity. In the laboratories of modern physics the elementary components of matter are studied. To do this, scientists sometimes build artificial atoms to help them understand the laws of matter. A research team at the Paul Scherrer Institute (Villigen/AG) uses a specifically modified helium atom to determine the exact mass and other properties of pions. Pions could help to understand more precisely where atomic nuclei get their mass from.

This workshop follows the submission of a community letter, which outlined the intention to organise a community workshop is to discuss options for a quantum technology development programme coordinated at the Europe-wide level. An even more mysterious form of energy called “dark energy” accounts for about 70% of the mass-energy content of the universe. This idea stems from the observation that all galaxies seems to be receding from each other at an accelerating pace, implying that some invisible extra energy is at work. Phillips, “Laser cooling and trapping of neutral atoms”, Rev. Mod. Ashkin, “Acceleration and trapping of particles by radiation pressure”, Phys. The process described above should therefore be seen as the fission of an incoming photon from the laser into a pair of photon and phonon – akin to nuclear fission of an atom into two smaller pieces.

Our low-temperature STM/AFM is based on a qPlus sensor design and is operated in an ultrahigh vacuum at a temperature of 5 K. Philipp Treutlein was recently appointed as a tenure-track assistant professor in the Department of Physics at the University of Basel. Together with Pascal Böhi, Max Riedel and several other co-workers he came from LMU Munich, where the group worked previously in the laboratory of Theodor Hänsch.

In 1998 two teams of astronomers working independently at Berkeley, California observed that supernovae – exploding stars – were moving away from Earth at an accelerating rate. Physicists had assumed that matter in the universe would slow its rate of expansion; gravity would eventually cause the universe to fall back on its centre. Though the Big Bang theory cannot describe what the conditions were at the very beginning of the universe, it can help physicists describe the earliest moments after the … Read More

The research alliance between Zurich and Karlsruhe is now united in the new Centre of Atomic Scale Technologies. Although the collaboration has only recently begun, the research groups involved were predestined for the task at hand. Thomas Schimmel is a pioneer of electronic circuits at the level of the atom, and Jürg Leuthold has demonstrated in his past research that photonic switches are possible at the atomic level. Moreover, Leuthold was the first researcher able to place both optical and electronic switching elements on the same chip. The tiny chip is also a modulator that can transform electrical signals into light signals and vice-versa—an extremely useful feature for transmitting data in fibre optic cables.

• Ultracold atoms react very sensitively to applied electromagnetic fields.
• In the first moments after the Big Bang, the universe was extremely hot and dense.
• We discovered and characterized reversible switches based on bond formation between a

The researchers have developed a component for microchips that’s just 10 nanometres long. But the fundamental innovation is less its size than that it functions at the atomic level. The nano-component is made of silver and platinum pads that approach one another until only a tiny gap remains.

and thus the spatial distribution of the microwave magnetic field component Bγ by measuring p2 for different values of the microwave power Pmw, see Figure 3 and . By measuring Bπ with B0 oriented along x, y, and z one can reconstruct the Cartesian microwave magnetic field amplitudes Bx, By and Bz. By measuring the circularly polarized components B+(–) for B0 along x, y and z , it is also possible to reconstruct the spatial distribution of relative phases between Bx, By and Bz.
