Is there an accelerating nonspreading wave packet in the Schrödinger equation with higher even-order dispersions?
Farrell Theodore Adriano, Hadi Susanto
Probably not. For Airy-type initial data, although nearly all lobes accelerate, the principal lobe remains essentially stationary. Moreover, the overall wave packet gradually dispe…
Spectral and Dynamical Properties of the Fractional Nonlinear Schrödinger Equation under Harmonic Confinement
R. Kusdiantara, M. F. Adhari, H. A. Mardi +2
We investigate the spectral and dynamical properties of the fractional nonlinear Schrödinger (fNLS) equation with harmonic confinement. In this setting, the classical Laplacian is…
New logarithmic power nonlinear Schrödinger equations with super-Gaussons
Hadi Susanto
We introduce a new class of nonlinear Schrödinger equations with a logarithmic-power nonlinearity that admits exact localized solutions of super-Gaussian form. The resulting statio…
Discrete equations and auto-traveling kinks of the model
H. Susanto, N. Karjanto
We study the model and derive two broad classes of lattice discretizations that admit static, translationally invariant kinks; that is, stationary kink profiles that can be…
Uncontrolled geostationary satellites: mapping periodic transitions to chaos with Lagrangian Descriptors
Roberto Flores, Jerome Daquin, Mauro Pontani +2
Uncontrolled geostationary satellites abandoned near an unstable equilibrium point of the equator experience irregular transitions between dynamical states (continuous circulation,…
In-band supratransmission in nonlinear flat band lattices
R. Kusdiantara, M. Wijaya, M. F. Adhari +1
Studying wave propagation in nonlinear discrete systems is essential for understanding energy transfer in lattices. While linear systems prohibit wave propagation within the natura…
