Easing uncertainty

Heisenberg's uncertainty principle, the fundamental impossibility of simultaneously measuring properties such as position and momentum, is at the heart of quantum theory. Physicists at ETH Zurich have now demonstrated an ...

A novel test bed for non-equilibrium many-body physics

The behavior of electrons in a material is typically difficult to predict. Novel insight comes now from experiments and simulations performed by a team led by ETH physicists who have studied electronic transport properties ...

The limits of friction

Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to ...

Can the causal order between events change in quantum mechanics?

Researchers at the University of Vienna and the Austrian Academy of Sciences develop a new theoretical framework to describe how causal structures in quantum mechanics transform. They analyse under which conditions quantum ...

Is glass transition driven by thermodynamics?

Glassy substances are everywhere, yet this state of matter is not completely understood. The basic picture is clear enough—glasses are solids that lack the regular atomic structure of a crystal. How and why they form, however, ...
