Geodynamics and artificial gravity in space-time crystals under slow perturbation and deformation
Anzhuoer Li, Liang Dong, Qian Niu
We present a theory of geodynamics in a space-time crystal based on an event wave packet constructed from the Floquet-Bloch waves, which not only involve a scalar dispersion functi…

Symmetry-breaking bifurcations of pure-quartic solitons in dual-core couplers
Pengfei Li, Liangliang Dong, Dumitru Mihalache +1
We investigate spontaneous symmetry- and antisymmetry-breaking bifurcations of solitons in a nonlinear dual-core waveguide with the pure-quartic dispersion and Kerr nonlinearity. S…
