$L^p$ - $L^q$ estimates for damped wave equations with odd initial data

Electronic Journal of Differential Equations, 2005
We study the Cauchy problem for the damped wave equation. In a previous paper [16] the author has shown the $L^p$ - $L^q$ estimates between the solutions of the damped wave equation and the solutions of the corresponding heat equation.

Approximate asymptotic integration of a higher order water-wave equation using the inverse scattering transform [PDF]

Nonlinear Processes in Geophysics, 1997
The complete mathematical and physical characterization of nonlinear water wave dynamics has been an important goal since the fundamental partial differential equations were discovered by Euler over 200 years ago.

Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

Advanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

High‐Entropy Magnetism of Murunskite

Advanced Functional Materials, EarlyView.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.
