Wave chaos in rapidly rotating stars [PDF]
Physical Review E, 2008 Effects of rapid stellar rotation on acoustic oscillation modes are poorly understood. We study the dynamics of acoustic rays in rotating polytropic stars and show using quantum chaos concepts that the eigenfrequency spectrum is a superposition of regular frequency patterns and an irregular frequency subset respectively associated with near-integrable ...

Some open questions in ‘wave chaos’ [PDF]
Nonlinearity, 2008 The subject area referred to as "wave chaos", "quantum chaos" or "quantum chaology" has been investigated mostly by the theoretical physics community in the last 30 years. The questions it raises have more recently also attracted the attention of mathematicians and mathematical physicists, due to connections with number theory, graph theory, Riemannian,

Wave Chaos for the Helmholtz Equation [PDF]
, 2010 This chapter is an introduction to the semiclassical approach for the Helmholtz equation in complex systems originating in the field of quantum chaos. A particular emphasis will be made on the applications of trace formulae in paradigmatic wave cavities known as wave billiards.

Chaos in a linear wave equation
Chaos, Solitons and Fractals: X, 2019 Abstract A linear partial differential equation is shown to exhibit three properties often used to define chaotic dynamics. The system comprises a one-dimensional wave equation with gain that operates on a semi-infinite line. A boundary condition enforces that the waves remain finite. It is shown that the resulting solution set is dense with periodic

Propagation of chaos and higher order statistics in wave kinetic theory [PDF]
Journal of the European Mathematical Society (Print), 2021 This manuscript continues and extends in various directions the result in arXiv:2104.11204, which gave a full derivation of the wave kinetic equation (WKE) from the nonlinear Schr\"{o}dinger (NLS) equation in dimensions $d\geq 3$.
