Fusion frames and g-frames

open access: yesJournal of Mathematical Analysis and Applications, 2008
The authors study generalized, i.e., \(g\)-frames in a Hilbert space \(U\), that is, sequences \((\Lambda_i)_{i\in I}\) of linear operators \(\Lambda_i:U\to V_i\) such that \[ A\| f\| ^2 \leq \sum_{i\in I} \| \Lambda_i f\| ^2 \leq B \| f\| ^2, \] for some positive constants \(A\) and \(B\).

Framing fusion and fission

Nature Materials, 2022
Engineering inter-triplet exchange coupling allows spin mixing between singlet and quintet manifolds in triplet–triplet pair states in metal–organic frameworks, demonstrating increased room-temperature triplet-fusion rates under relatively small applied magnetic fields.
