With black phosphorus, physicists measure the full quantum metric tensor and unlock a new view of electrons in solids.

Because the quantum metric tensor is highly relevant in understanding fundamental physical phenomena in solids, developing an effective method for its direct measurement is crucial.

Conceptually, the metric tensor defines how spacetime itself is curved. Its curvature is dependent on the matter, energy and stresses present within it; the contents of your Universe define its ...

The metric tensor of spacetime tells us how lengths determine in spacetime. The metric tensor also thus determines the curvature properties of spacetime. Curvature is what we feel as "force." In ...

In the present paper, we have considered a cubic (α, β) metric which is an special class of p-power Finsler metric, and obtained the conditions under which the Finsler space with such special metric ...

The purpose of this paper is to obtain equations of motion for a system of massive bodies of finite size moving in the gravitational field of the system. In the Eulerian form of Newtonian mechanics ...

The quantum metric—a key measure of the quantum distance in solid-state materials—helps determine the electronic properties of solids, such as transport phenomena. While scientists ...
