Observation of an anti-PT-symmetric exceptional point and energy-difference conserving dynamics in electrical circuit resonators

The study of parity-time (PT) symmetric optical systems has recently attracted much attention. Here, the authors experimentally study an anti-PT symmetric circuit system and observe an exceptional point with an inverse PT symmetry breaking transition and energy-difference conserving dynamics.
