Exploring quantum systems that don't find equilibrium

Some physical systems, especially in the quantum world, do not reach a stable equilibrium even after a long time. An ETH researcher has now found an elegant explanation for this phenomenon.

Remarkable things happen when a "squishy" compound of manganese and sulfide (MnS2) is compressed in a diamond anvil, say researchers from the University of Rochester and the University of Nevada, Las Vegas (UNLV).

Why beer mats do not fly in a straight line

Anyone who has ever failed to throw a beer mat into a hat should take note: physicists at the University of Bonn have discovered why this task is so difficult. However, their study also suggests how to significantly increase accuracy and range. The results are being publishing in the European Physical Journal Plus.

How quantum fields could be used to break low-temperature records

At first glance, heat and cold do not have much to do with quantum physics. A single atom is neither hot nor cold. Temperature can traditionally only be defined for objects that consist of many particles. But at TU Wien, in collaboration with FU Berlin, Nanyang Technological University in Singapore and the University of Lisbon, it has now been possible to show what possibilities arise when thermodynamics and quantum physics are combined: One can specifically use quantum effects to cool a cloud of ultracold atoms even further.

Promising new technique is bringing the microscopic details of the brain into sharper focus

On the hunt for 'hierarchical' black holes

Black holes, detected by their gravitational wave signal as they collide with other black holes, could be the product of much earlier parent collisions. Such an event has only been hinted at so far, but scientists at the University of Birmingham in the U.K., and Northwestern University in the U.S., believe we are getting close to tracking down the first of these so-called "hierarchical" black holes.

Three dwarf spheroidal galaxies found to rotate

An international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science Institute (STScI, U.S.) has discovered the presence of transverse rotation (in the plane of the sky) in three dwarf spheroidal galaxies. These are a very faint type of galaxy and are quite difficult to observe. These new findings help to trace their evolutionary history. The finding was made using the most recent data from the GAIA satellite of the European Space Agency. The results of the study have just been published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).
