Exactly Solvable Many-Body Systems and Pseudo-Hermitian Point Interactions
arXiv:quant-ph/0402185 · doi:10.1023/B:CJOP.0000014366.93476.92
Abstract
We study Hamiltonian systems with point interactions and give a systematic description of the corresponding boundary conditions and the spectrum properties for self-adjoint, PT-symmetric systems and systems with real spectra. The integrability of one dimensional many body systems with these kinds of point (contact) interactions are investigated for both bosonic and fermionic statistics.
