- Abstract: We show that in order to guide waves, it is sufficient to periodically
truncate their edges. The modes supported by this type of wave guide propagate
freely between the slits, and the propagation pattern repeats itself. We
experimentally demonstrate this general wave phenomenon for two types of waves:
(i) plasmonic waves propagating on a metal-air interface that are periodically
blocked by nanometric metallic walls, and (ii) surface gravity water waves
whose evolution is recorded, the packet is truncated, and generated again to
show repeated patterns. This guiding concept is applicable for a wide variety
of waves.

We demonstrate the controllable generation of distinct types of dispersive shock-waves emerging in a quantum droplet bearing environment.
Surprisingly, dispersive shock waves persist across the hyperbolic-to-elliptic threshold.
A plethora of additional wave patterns arise, such as rarefaction waves, traveling dispersive shock waves, (anti)kinks and droplet wavetrains.

This work is a study of acoustic non-reciprocity exhibited by a passive one-dimensional linear waveguide incorporating two local strongly nonlinear, asymmetric gates.
The maximum transmissibility reaches as much as 40%, and the transmitted energy from upstream to downstream varies up to nine orders of magnitude, depending on the direction of wave propagation.

Resonant transmission occurs when constructive interference results in the complete passage of an incoming wave through an array of barriers.
We adopt wave packets with finite width to illustrate the deterioration of resonance with decreasing wave packet width.
A comparison with exact numerical calculations shows excellent agreement, and provides insight into the scattering process.

We discuss the semi-classical transverse trapping of waves by means of an inhomogeneous gauge field.
We show that, due to the Kapitza effect, an effective potential proportional to the square of the transverse derivative of the delay arises.

The shape of the wave varies periodically as a manifestation of its peculiar properties of nonstaticity.
The mechanism underlying the abnormal features of nonstatic light waves demonstrated here can be interpreted by the rotation of the squeezed-shape contour of the Wigner distribution function in phase space.

Time-periodic Hamiltonians can be exploited to increase the dephasing time of qubits and to design protected one and two-qubit gates.
Here, we use the framework of many-mode Floquet theory to describe approaches to robustly control Floquet qubits in the presence of multiple drive tones.
Following the same approach, we introduce a longitudinal readout protocol to measure the Floquet qubit without the need of first adiabatically mapping back the Floquet states to the static qubit states.

We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit.
We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront.
The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
