Determination of the characteristic directions of lossless linear optical elements
Hanno Hammer
We show that the problem of finding the primary and secondary characteristic directions of a linear lossless optical element can be reformulated in terms of an eigenvalue problem r…
Collective states in highly symmetric atomic configurations, and single-photon traps
Hanno Hammer
Abbreviated Abstract: We study correlated states in a circular and linear-chain configuration of identical two-level atoms containing the energy of a single quasi-resonant photon i…
Collective excitations in circular atomic configurations, and single-photon traps
Hanno Hammer
Correlated excitations in a plane circular configuration of identical atoms with parallel dipole moments are investigated. The collective energy eigenstates, their level shifts and…
Characteristic Parameters in Integrated Photoelasticity: An Application of Poincare's Equivalence Theorem
Hanno Hammer
The Poincare Equivalence Theorem states that any optical element which contains no absorbing components can be replaced by an equivalent optical model which consists of one linear…
