The authors employ topolectric circuits to realize a non-Hermitian topological Hopf bundle state of matter, which allows them to observe the emergence of phases that are unique to non-Hermitian systems. The proposed non-Hermitian Hopf bundle platform and visualization methodology pave the way for designing new topologically robust non-Hermitian phases of matter.
