Weyl points on non-orientable manifolds
André Grossi Fonseca, Sachin Vaidya, Thomas Christensen +3
Weyl fermions are hypothetical chiral particles that can also manifest as excitations near three-dimensional band crossing points in lattice systems. These quasiparticles are subje…

Stability of topologically protected slow light against disorder
Jonas F. Karcher, Sarang Gopalakrishnan, Mikael C. Rechtsman
Slowing down light in on-chip photonic devices strongly enhances light-matter interaction, but typically also leads to increased backscattering and small-bandwidth operation. It wa…

Optical control of topological end states via soliton formation in a 1D lattice
Christina Jörg, Marius Jürgensen, Sebabrata Mukherjee +1
Solitons are self-consistent solutions of the nonlinear Schrödinger equation that maintain their shape during propagation. Here we show, using a pump-probe technique, that soliton…
