Moments and saturation properties of eigenstates
Martin Bojowald, Jonathan Guglielmon, Martijn van Kuppeveld
Eigenvalues are defined for any element of an algebra of observables and do not require a representation in terms of wave functions or density matrices. A systematic algebraic deri…

Landau levels in strained two-dimensional photonic crystals
J. Guglielmon, M. C. Rechtsman, M. I. Weinstein
The principal use of photonic crystals is to engineer the photonic density of states, which controls light-matter coupling. We theoretically show that strained 2D photonic crystals…
