Resolving the invariant subspace problem for operators on Hilbert spaces has been stubbornly difficult, and it is this which Enflo claims to have achieved. This time Enflo answers in the affirmative: ...

In a study published in Reports on Progress in Physics, researchers have achieved device-independent characterization of genuinely entangled subspaces (GESs) in both optical and superconducting ...

In the world of "Star Trek," just about every technology that makes Starfleet's explorations possible hinges on the existence of one discovery: subspace physics. An amorphous fictional construct ...
