Generalized local interactions in 1D: solutions of quantum many-body systems describing distinguishable particles
Martin Hallnäs, Edwin Langmann, Cornelius Paufler
As is well-known, there exists a four parameter family of local interactions in 1D. We interpret these parameters as coupling constants of delta-type interactions which include dif…

Exact solutions of two complementary 1D quantum many-body systems on the half-line
Martin Hallnäs, Edwin Langmann
We consider two particular 1D quantum many-body systems with local interactions related to the root system . Both models describe identical particles moving on the half-line w…
