Oscillatory Secular Modes: The Thermal Micropulses

Aims. Stars in the narrow mass range of about 2.5 and 3.5M⊙ can develop a thermally unstable He-burning shell during its ignition phase. We study, from the point of view secular stability theory, these so called thermal micropulses and we investigate their properties; the thermal pulses constitute a convenient conceptual laboratory to look thoroughly into the physical properties of a helium-bur...

Quantum super-oscillation of a single photon

Super-oscillation is a counterintuitive phenomenon describing localized fast variations of functions and fields that happen at frequencies higher than the highest Fourier component of their spectra. The physical implications of this effect have been studied in information theory and optics of classical fields, and have been used in super-resolution imaging. As a general phenomenon of wave dynam...

Shape-invariant pulses in resonant linear absorbers.

We theoretically describe ultrashort self-similar pulses propagating in coherent linear absorbers near optical resonance and propose a method for their experimental realization.

Stability of Traveling Pulses with Oscillatory Tails in the FitzHugh-Nagumo System

The FitzHugh-Nagumo equations are known to admit fast traveling pulses that have monotone tails and arise as the concatenation of Nagumo fronts and backs in an appropriate singular limit, where a parameter ε goes to zero. These pulses are known to be nonlinearly stable with respect to the underlying PDE. Recently, the existence of fast pulses with oscillatory tails was proved for the FitzHugh-N...
