Chaotic classical systems exhibit extreme sensitivity to small changes in their initial conditions. In a spin chain, chaos can be tracked not only in time, but in space. The propagation of small changes in the initial conditions results in a “light cone” bounding the spatial region and time interval when the trajectories have diverged. For nearest-neighbour interactions, the light cone...

We theoretically investigate Weyl superconductivity in quasicrystals. Weyl superconductivity is a topological phase in three-dimensional crystals with topologically protected point nodes in the Brillouin zone called Weyl nodes, at which the Chern number changes its value [1]. Quasicrystals (QCs) are materials whose structure is aperiodic with a long-range order. As they lack translational...

Majorana-based quantum computing harnesses the non-Abelian exchange statistics of Majorana zero modes (MZMs) in order to perform gate operations via braiding. It is paramount that braiding protocols keep a given system within its ground state subspace, as transitions to excited states lead to decoherence and constitute a “diabatic error.” Typical braiding protocols are envisioned on networks...

Many topologically non-trivial systems have local topological invariants which cancel over the full Brillouin zone. Yet such systems could be platforms for non-abelian physics, for example nodal superconductors potentially hosting Majorana modes. Experimentally distinguishing signatures from local non-trivial topology to similar trivial features is not a clear-cut process. Our work extends the...
