Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids ...

Quantum geometry describes quantum states in systems with changing system parameters, such as an electron spinning in a magnetic field whose direction is slowly changing. The state of the electron ...

A new breakthrough may help scientists solve some of the mysteries of the quantum realm. For the first time, physicists have been able to measure the geometrical 'shape' a lone electron adopts as it ...

In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets. These materials exhibit a unique type of magnetism ...

Quantum geometry leap: Researchers extended quantum geometry to non-Hermitian photonic systems, enabling direct measurement of the quantum metric and programmable light potentials. Dark matter link: A ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? By hot swapping similar ideas, scientists built a model of quantum geometry that they ...

Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...

The geometry or shape of a quantum system is mathematically expressed by a tool called the quantum geometric tensor (QGT). It also explains how a quantum system's state changes when we tweak certain ...

Quantum geometry is a mathematical tool that describes how quantum states change with the parameters of a system. This abstract geometric description helps researchers, for example, to better ...

A collaboration between Stuart Parkin’s group at the Max Planck Institute of Microstructure Physics in Halle (Saale) and Claudia Felser’s group at the Max Planck Institute for Chemical Physics of ...
