Two interacting fermions in a 1D harmonic trap: matching the Bethe ansatz and variational approaches
D. Rubeni, A. Foerster, I. Roditi
In this work, combining the Bethe ansatz approach with the variational principle, we calculate the ground state energy of the relative motion of a system of two fermions with spin…

Quantum phase transitions in Bose-Einstein condensates from a Bethe ansatz perspective
D. Rubeni, A. Foerster, E. Mattei +1
We investigate two solvable models for Bose-Einstein condensates and extract physical information by studying the structure of the solutions of their Bethe ansatz equations. A care…
