Topological Defect Engineering and PT Symmetry in Non-Hermitian Electrical Circuits.
Physical review lettersWe employ electric circuit networks to study topological states of matter in non-Hermitian systems enriched by parity-time symmetry PT and chiral symmetry anti-PT (APT). The topological structure manifests itself in the complex admittance bands which yields excellent measurability and signal to noise ratio.

Electric Springs: Basic Principles, Circuit Topologies and Applications to Smart Grids
2017Traditional control paradigm of 'power supply following demand' does not suit emerging power grids that are fed with increasing renewable energy generation of intermittent nature. In order to achieve power system stability, it is necessary to maintain instantaneous balance between power supply and demand.
