High-frequency nonlinear conductivity of a Wigner crystal
A. J. Schleusner, M. T. Elewa, N. R. Beysengulov +2
Electrons trapped above the surface of superfluid helium are a disorder-free platform for investigating the formation and dynamics of low-dimensional Wigner crystals. A characteris…

Dispersive mode coupling in -doped semiconductor nanomechanical resonators
Ankang Liu, Mahmoud T. Elewa, Mark I. Dykman
Dispersive coupling between vibrational modes with different frequencies is a major nonlinear dynamical effect. We show that in -doped semiconductors such coupling is strongly e…

Anomalous parametric resonance in a spin-1/2 chain: dynamical effects of nontrivial topology
Mahmoud T. Elewa, M. I. Dykman
Resonant parametric modulation is a major tool of studying magnetic systems. For a spin-1/2 chain in a strong magnetic field, the resulting excitations can be mapped on fermionic e…
