Mobile gravimetry is an important technique in metrology, navigation, geodesy and geophysics. Although atomic gravimeters are presently used for accuracy, they are constrained by instrumental fragility and complexity. In ...
A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, "non-Gaussian" noise processes that are routinely encountered in superconducting ...

Topological states of matter are phases of matter that go beyond the Landau symmetry-breaking theory, which are characterized by topological invariants and topological edge states. Physicist David J. Thouless, in collaboration ...
Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics ...
Certain materials, like copper, conduct electricity very well. Other materials, like glass, do not. A certain kind of material, called a topological insulator, acts partially like one and partially like the other ― it ...
