Spinor Bose-Einstein condensate as an analog simulator of molecular bending vibrations
Spinor Bose-Einstein condensates (BECs) simulate molecular bending and stretching vibrations by mapping their Hamiltonian to a two-dimensional vibron model. The study shows that transitioning between linear and bent molecular configurations in the BEC generates significant entanglement, providing non-Gaussian fluctuations as a dynamical witness for quantum phase transitions.
