Flat band states: disorder and nonlinearity
Daniel Leykam, Sergej Flach, Omri Bahat-Treidel +1
We study the critical behaviour of Anderson localized modes near intersecting flat and dispersive bands in the quasi-one-dimensional diamond ladder with weak diagonal disorder .…
Nonlinear wave dynamics in honeycomb lattices
Omri Bahat-Treidel, Mordechai Segev
We study the nonlinear dynamics of wave packets in honeycomb lattices, and show that, in quasi-1D configurations, the waves propagating in the lattice can be separated into left-mo…
PT-symmetry in honeycomb photonic lattices
Alexander Szameit, Mikael C. Rechtsman, Omri Bahat-Treidel +1
We apply gain/loss to honeycomb photonic lattices and show that the dispersion relation is identical to tachyons - particles with imaginary mass that travel faster than the speed o…
Breakdown of Dirac Dynamics in Honeycomb Lattices due to Nonlinear Interactions
Omri Bahat-Treidel, Or Peleg, Hrvoje Buljan +1
We study the dynamics of coherent waves in nonlinear honeycomb lattices and show that nonlinearity breaks down the Dirac dynamics. As an example, we demonstrate that even a weak no…
Prefect Klein tunneling in anisotropic graphene-like photonic lattices
Omri Bahat-Treidel, Or Peleg, Mark Grobman +3
We study the scattering of waves off a potential step in deformed honeycomb lattices. For small deformations below a critical value, perfect Klein tunneling is obtained. This means…
The (ir)Relevance of Initial Conditions in Soft Leptogenesis
Omri Bahat-Treidel, Ze'ev Surujon
We explore how the initial conditions affect the final lepton asymmetry in Soft Leptogenesis. It has been usually assumed that the initial state is a statistical mixture of sterile…
