In a preprint posted to arXiv, researchers proposed a non-Abelian version of the Hatano-Nelson model that incorporates a nonreciprocal U(2) gauge field and then built it using electric circuits to test the idea. The experiment revealed two distinctive effects: complex energy spectra braided into a Hopf-link shape and a bipolar skin effect where modes localize at both ends of the system under non-Abelian conditions. This is the first experimental exploration of non-Hermitian systems with non-Abelian gauge fields; prior work stayed within Abelian or gauge-free setups. The methodology involved designing and measuring admittance in custom electric circuits that simulate the model. As an arXiv preprint (https://arxiv.org/abs/2603.24642), the work has not yet been peer-reviewed. Limitations include its restriction to artificial circuit systems rather than natural materials and the absence of large-scale replication or sample-size statistics typical of other experimental fields.
