Optically anisotropic media: New approaches to the dielectric function, singular axes, microcavity modes and Raman scattering intensities
Marius Grundmann, Chris Sturm, Christian Kranert, Steffen Richter, Rüdiger Schmidt-Grund, Christianne Deparis, and Jesús Zúñiga-Pérez
The anisotropic optics (novel theory of Raman scattering off the principal axes) and the singular optics (spectral dispersion of Windungsachsen from generalized ellipsometry) in monoclinic gallia are reviewed. The latter represent exceptional points, a property of complex symmetric matrices, and are predicted to also exist in anisotropic microcavities leading to circularly polarized eigenstates.

Selective emitters for thermophotovoltaic applications
Nicole A. Pfiester and Thomas E. Vandervelde
The dramatic improvement of III–V film quality in the past decade has caused a resurgence in thermophotovoltaic (TPV) cell development. The selective emitter, as part of the complete TPV system, allows use of a wide range of energy sources. Early development of these emitters utilized inherent atomic properties while more recent technologies leverage complex electromagnetic effects to engineer custom solutions.

Phonon broadening from supercell lattice dynamics: Random and correlated disorder
Alistair R. Overy, Arkadiy Simonov, Philip A. Chater, Matthew G. Tucker, and Andrew L. Goodwin
Disorder broadens phonons, but can it also change the fundamental shape of the phonon dispersion curves? In this paper, a supercell lattice dynamical method is developed that determines the effect of static disorder on the form of the phonon dispersion curves. The authors show that both the nature and extent of disorder can have dramatic and non-trivial effects on vibrational states.
