We review recent progress in analysing wave scattering in systems with both intrinsic chaos
and/or disorder and internal losses, when the scattering matrix is no longer unitary. By …

We quantify the presence of direct processes in the S matrix of chaotic microwave cavities
with absorption in the one-channel case. To this end the full distribution PS (S) of the S …

Some scaling properties for classical light ray dynamics inside a periodically corrugated
waveguide are studied by use of a simplified two-dimensional nonlinear area-preserving …

We consider mechanisms of formation of the bound states in the continuum in open
rectangular quantum dots with variable width. Because of symmetry there might be bound …

The description of open quantum system successfully uses the concept of the effective
Hamiltonian, which takes into account the coupling to the environment. The concept can be …

We reveal a general explicit relation between the statistics of delay times in one-channel
reflection from a mesoscopic sample of any spatial dimension and the statistics of the …

We compute the electron transmission through a multiripple electron waveguide. The
multiripple waveguide behaves like a sequence of quantum dots. Quasibound states in the …

We show that a network of ballistic electron waveguides can generate entangled Bell-like
states from separable states when it is resonant. The network we study is grouped into …

We observe time-periodic echoes in the transmitted electron probability for a quantum
waveguide with a ripple cavity. Knowing the period of the echoes, we can determine the …

The escape dynamics of a classical light ray inside a corrugated waveguide is characterised
by the use of scaling arguments. The model is described via a two-dimensional nonlinear …
