High-order exceptional point based optical sensor
Web1 Sep 2024 · In a different context, it has been recently proposed and soon after demonstrated that the sensitivity of single-nanoparticle detection based on mode splitting at exceptional points (EPs) in WGM microcavities is enhanced compared to that at diabolic points (DPs) [26]. Web8 Aug 2024 · An exceptional point of order n is a point in parameter space at which n eigenvalues and the corresponding eigenstates of a non-Hermitian Hamiltonian coalesce. At an EP, a given non-Hermitian Hamiltonian is no longer diagonalizable, but instead can be brought to a matrix containing at least one Jordan block via a similarity transformation. coffee vending machine size
