An international team of researchers (Germany, Italy, USA – University of Maryland) has accomplished synthetic topological matter in electric circuit networks. The main motif of topological matter is its role in hosting particularly stable and robust features immune to local perturbations, which might be a pivotal ingredient for future quantum technologies. The current results promise a knowledge transfer from electric circuits to alternative optical platforms. Topolectric circuits create an experimental and theoretical inspiration for new avenues of topological matter and might have a particular bearing on future applications in photonics. The flexibility, cost-efficiency, and versatility of topolectric circuits is unprecedented, and might constitute a paradigm change in the field of synthetic topological matter. The findings unveil a future route for topological defect engineering and tuning in non-Hermitian systems of arbitrary dimension…read more. TECHNICAL ARTICLE
