Quantum critical dynamics in a spinor Hubbard model quantum simulator

Abstract

Three-dimensional (3D) strongly correlated many-body systems and their dynamics across quantum phase transitions pose a challenge when it comes to numerical simulations. The authors experimentally demonstrated that such many-body dynamics can be efficiently studied in a 3D spinor Bose–Hubbard model quantum simulator, and observed dynamics and scaling effects beyond the scope of existing theories at superfluid–insulator quantum phase transitions.
