DOI: 10.1007/s00211-021-01218-3
Abstract: An energy-conserving and an energy-and-enstrophy conserving numerical schemes are derived, by approximating the Hamiltonian formulation, based on the Poisson brackets and the vorticity-divergence variables, of the inviscid shallow water flows. The conservation of the energy… read more here.

DOI: 10.1103/physrevx.10.021043
Abstract: An extension to wave turbulence theory shows that in a system of nonlinear waves, correlations among the waves arise, causing ``ghost'' excitations that lead to coherent structures in physical space. read more here.

DOI: 10.1364/oe.25.028556
Abstract: We show that the group-velocity-led optical event horizon (OEH) in optical fibers provides a convenient way to actively control the propagation property of higher-order solitons by a comparatively weak dispersive wave (DW) pulse. It has… read more here.
