Ultracold quantum gases serve as ideal models for the characterization of universal
properties of a variety of phenomena in quantum systems. In a formal analogy to …

Quantum chaos is generally referred to as the study of quantum manifestations or
fingerprints of nonlinear dynamical and chaotic behaviors in the corresponding classical …

Experiments with superconducting microwave cavities have been performed in our
laboratory for more than two decades. The purpose of the present article is to recapitulate …

Disorder at etched edges of graphene quantum dots (GQD) enables random all-to-all
interactions between localized charges in partially filled Landau levels, providing a potential …

Multifractal analysis is a powerful approach for characterizing ergodic or localized nature of
eigenstates in complex quantum systems. In this context, the eigenvectors of random …

We determined experimentally the eigenvalues of two rectangular quantum billiards that
contain circular scatterers forming a triangular grid, so-called Dirac billiards. For this we …

The development of chaos theory has fundamentally changed our understanding of a large
variety of nonlinear dynamical phenomena. The question of what chaos can do to a …

We study distributions of the ratios of level spacings of rectangular and Africa-shaped
superconducting microwave resonators containing circular scatterers on a triangular grid, so …

A crucial result in quantum chaos, which has been established for a long time, is that the
spectral properties of classically integrable systems generically are described by Poisson …

The nonlinear responses and stability of double-layered nanoplate embedded in the elastic
medium are investigated in the presence of 3: 1 internal resonance. By the nonlocal theory …
