We have theoretically investigated the time-symmetry breaking phasetransition process for two discrete states coupled with a one-dimensionalcontinuum by solving the nonlinear eigenvalue prob- lem for the effectiveHamiltonian associated with the discrete spectrum. We obtain the effectiveHamiltonian with use of the Feshbach-Brillouin-Wigner projection method. Strongenergy depen- dence of the self-energy appearing in the effective Hamiltonianplays a key role in the time-symmetry breaking phase transition: as a result ofcompetition in the decay process between the Van Hove singularity and the Fanoresonance, the phase transition becomes a higher-order transition when both thetwo discrete states are located near the continuum threshold.
