Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation
in various transparent media such as air (gases), transparent solids and liquids. The …

Abstract de Broglie wave packets accompanying moving particles are dispersive and lack
an intrinsic length scale solely dictated by the particle mass and velocity. Mackinnon …

In this work, starting by suitable superpositions of equal-frequency Bessel beams, we
develop a theoretical and experimental methodology to obtain localized stationary wave …

In this work, in terms of suitable superpositions of equal-frequency Bessel beams, we
develop a theoretical method to obtain localized stationary wave fields, in absorbing media …

In recent experiments, localized and stationary optical wave packets have been generated
in second-order nonlinear processes with femtosecond pulses, whose asymptotic features …

Angular dispersion can counterbalance normal group‐velocity dispersion (GVD) that
increases the wave‐vector length in a dispersive medium. By tilting the wave vector, angular …

Spatiotemporal optical wavepackets refer to light fields with sophisticated structures in both
space and time. The ability to produce such spatiotemporally structured optical wavepackets …

We predict that an ultracold Bose gas in an optical lattice can give rise to a new form of
condensation, namely, nonspreading 3D wave packets that reflect the symmetry of the …

In this work it is shown how to obtain, in a simple way, localized (nondiffractive) subluminal
pulses as exact analytic solutions to the wave equations. These ideal subluminal solutions …
