In an ideal perfectly straight multimode fiber with a circular core, the symmetry ensures that
rotating the input wave front leads to a corresponding rotation of the output wave front. This …

Stable laser resonators support three fundamental families of transverse modes: the
Hermite, Laguerre, and Ince Gaussian modes. These modes are crucial for understanding …

Abstract The Ince-Gauss beams, separable in elliptic coordinates, are studied through a ray-
optical approach. Their ray structure can be represented over a Poincaré sphere by …

In an ideal perfectly straight multimode fiber with a circular-core, the symmetry ensures that
rotating the input wavefront leads to a corresponding rotation of the output wavefront. This …

We provide a new perspective on quantum dynamical phase transitions (DPTs) by
explaining their origin in terms of caustics that form in the Fock space representation of the …

We consider the topological properties of the so-called central spin model that consists of $
N $ identical spins coupled to a single distinguishable central spin which arises in physical …
