On Small Beams with Large Topological Charge
Mario Krenn, Nora Tischler, Anton Zeilinger
Light beams can carry a discrete, in principle unbounded amount of angular momentum. Examples of such beams, the Laguerre-Gauss modes, are frequently expressed as solutions of the…
Topological metrology and its application to optical position sensing
Nora Tischler, Mathieu L. Juan, Sukhwinder Singh +4
We motivate metrology schemes based on topological singularities as a way to build robustness against deformations of the system. In particular, we relate reference settings of met…
Necessary symmetry conditions for the rotation of light
Ivan Fernandez-Corbaton, Xavier Vidal, Nora Tischler +1
Two conditions on symmetries are identified as necessary for a linear scattering system to be able to rotate the linear polarisation of light: Lack of at least one mirror plane of…
The role of angular momentum in the construction of electromagnetic multipolar fields
Nora Tischler, Xavier Zambrana-Puyalto, Gabriel Molina-Terriza
Multipolar solutions of Maxwell's equations are used in many practical applications and are essential for the understanding of light-matter interactions at the fundamental level. U…
Electromagnetic duality symmetry and helicity conservation for the macroscopic Maxwell's equations (previously "Experimental demonstration of electromagnetic duality symmetry breaking")
Ivan Fernandez-Corbaton, Xavier Zambrana-Puyalto, Nora Tischler +4
Modern physics is largely devoted to study conservation laws, such as charge, energy, linear momentum or angular momentum, because they give us information about the symmetries of…
Scattering in Multilayered Structures: Diffraction from a Nanohole
Ivan Fernandez-Corbaton, Nora Tischler, Gabriel Molina-Terriza
The spectral expansion of the Green's tensor for a planar multilayered structure allows us to semi analytically obtain the angular spectrum representation of the field scattered by…
