Abstract
We obtain a generic formula for the distribution of Yang-Lee zeros of one-d imensional quantum many-body systems solvable by the Bethe ansatz and the Y ang-Yang thermodynamic formalism. We find that the zeros are located on the negative real axis of the complex fugacity plane and thus prove that no ph ase transition occurs in these one-dimensional systems, as proved by others using different methods. [S1063-651X(99)08101-5].
