Topology of Bloch Bands from Cauchy Data
Didier Felbacq, Emmanuel Rousseau
In a previous work, the topology of inversion-symmetric one-dimensional periodic media was characterized through the pole-zero pattern of an impedance-like function associated with…

Comment on ``Near-field spin Chern number quantized by real-space topology of optical structures''
Didier Felbacq, Emmanuel Rousseau
In the reference Phys. Rev. Lett. 132, 233801 (2024), the authors claim to have introduced a ''real-space spin Chern number'' as well as a ''Spin Berry connection'' and a ''Spin Be…

Comment on ''Photonic Band Gaps: Noncommuting limit and the 'Acoustic Band'''
Didier Felbacq
This comment concerns the homogenization of 2D dielectric photonic crystals, and the fact that the limits ( is the Bloch vector) and do not commute for…
