We report on experimental studies that were performed with a microwave Dirac billiard (DB),
that is, a flat resonator containing metallic cylinders arranged on a triangular grid, whose …

We report on the realization of a graphene billiard with a fourfold rotational symmetry, which
has the shape of a billiard with chaotic classical dynamics. The eigenstates are separated …

Topological photonic insulators provide a novel approach to achieve high-efficiency
terahertz transmissions due to the presence of the topological edge states. In this work, the …

Rectangular billiards have two mirror symmetries with respect to perpendicular axes and a
twofold (fourfold) rotational symmetry for differing (equal) side lengths. The eigenstates of …

Abstract According to the Berry–Tabor conjecture, the spectral properties of typical
nonrelativistic quantum systems with an integrable classical counterpart agree with those of …

We investigate the spectral properties and Husimi functions of relativistic quantum billiards
(QBs) consisting of a spin-1/2 particle governed by the Dirac equation and confined to a …

We present experimental and numerical results for the fluctuation properties in the
eigenfrequency spectra and of the scattering matrix of closed and open unidirectional …

A classical billiard (CB)[1–3] consists of a bounded two-dimensional domain, in which a
point particle moves freely and is reflected specularly at the boundary. Billiards have the …

The statistical properties of wave chaotic systems of varying dimensionalities and
realizations have been studied extensively. These systems are commonly characterized by …

We study fluctuation properties in the energy spectra of finite-size honeycomb lattices—
graphene billiards—subject to the Haldane-model on-site potential and next-nearest …
