Quantum Phase Transition in the Coupled-Top Model: From <i>Z</i><sub>2</sub> to U(1) Symmetry Breaking
We investigate the coupled-top model, which describes two large spins interacting along both <i>x</i> and <i>y</i> directions. By tuning coupling strengths along distinct directions, the system exhibits different symmetries, ranging from a discrete <inline-formula><m...
