Existence and stability of PT-symmetric vortices in nonlinear two-dimensional square lattices
Haitao Xu, Panayotis G. Kevrekidis, Dmitry E. Pelinovsky
Vortices symmetric with respect to simultaneous parity and time reversing transformations are considered on the square lattice in the framework of the discrete nonlinear Schrödinge…
Irreversibility and small-scale generation in 3D turbulent flows
Alain Pumir, Haitao Xu, Rainer Grauer +1
In three-dimensional turbulent flows energy is supplied at large scales and cascades down to the smallest scales where viscosity dominates. The flux of energy through scales implie…
Lagrangian view of time irreversibility of fluid turbulence
Haitao Xu, Alain Pumir, Eberhard Bodenschatz
A turbulent flow is maintained by an external supply of kinetic energy, which is eventually dissipated into heat at steep velocity gradients. The scale at which energy is supplied…
Traveling waves for the Mass in Mass model of granular chains
Panayotis G. Kevrekidis, Atanas G. Stefanov, Haitao Xu
In the present work, we consider the mass in mass (or mass with mass) system of granular chains, namely a granular chain involving additionally an internal resonator. For these cha…
