Non-Hermitian concept has generalized the notion of band topology with associated exceptional points (EPs), also known as the parity-time symmetry breaking points, leading to the counter-intuitive phenomena. Non-Hermitian skin effect, involving the accumulation of eigenstates at the boundary, is one such circumstance, but its realization in a high dimensional quantum system remains...
During the last twenty years, optical lattices have emerged as powerful quantum simulators to study the many-body physics of (strongly) interacting particles in, initially, periodic potentials. This has then been extended to 1D quasiperiodic models such as the Aubry-Andre model, mostly to study localisation phenomena.
We have generalized these techniques to an 8-fold rotationally symmetric...
