Description
The energies of low-lying bound states of a microscopic quantum many-body system of particles can be worked out in a reduced Hilbert space. We present here and test a specific non-perturbative algorithm. We also show that real exceptional points which may be present in the spectrum can be identified as fixed points of coupling constants in the truncation procedure
