文摘An equivalence is made between the exceptional points proposed by the field of non-Hermitian quantum mechanics and the dead band observed in laser gyroscopes.The sensitivity enhancement near this exceptional point is plagued by increased uncertainty due to broadening of the beat-note bandwidth.Also,near the dead band the gyroscope response is caused by Rabi intensity oscillations and not solely by a phase modulation.Finally,a distinction is made between conservative and non-conservative coupling.
