How complex oscillations in a quantum system simplify with time

Quantum physics allows to make statements about the behavior of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values, ...

New state of matter in one-dimensional quantum gas

As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling through ancient Egypt that would later bear his name. It was a machine consisting of a screw housed inside a hollow ...

Physicists observe competition between magnetic orders

They are as thin as a hair, only a hundred thousand times thinner—so-called two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They became known to a wider audience ...

Quantum wave in helium dimer filmed for the first time

Anyone entering the world of quantum physics must prepare themself for quite a few things unknown in the everyday world: Noble gases form compounds, atoms behave like particles and waves at the same time and events that in ...

Multiparty entanglement: When everything is connected

Entanglement is an ubiquitous concept in modern physics research: it occurs in subjects ranging from quantum gravity to quantum computing. In a publication that appeared in Physical Review Letters last week, UvA-IoP physicist ...

Topological phases in biological systems

LMU physicists have shown that topological phases could exist in biology, and in so doing they have identified a link between solid-state physics and biophysics.

Artificial Chemist 2.0: Quantum dot R&D in less than an hour

A new technology, called Artificial Chemist 2.0, allows users to go from requesting a custom quantum dot to completing the relevant R&D and beginning manufacturing in less than an hour. The tech is completely autonomous, ...

Simplifying long-range quantum interactions in many-body systems

Calculations for certain quantum systems whose parts interact over long distances will be much easier to perform thanks to the work of a RIKEN physicist and his collaborator, who have extended an assumption that holds for ...
