Exceptional Points and Braiding Topology in Non-Hermitian Systems with long-range coupling

We present a study of complex energy braiding in a 1D non-Hermitian system with $n$th order long range asymmetrical coupling. Our work highlights the emergence of novel topological phenomena in such systems beyond the conventional nearest-neighbor interaction. The modified SSH model displays $n$ distinct knots and links combinations in the …
