Continuous Symmetry Breaking in a Trapped-Ion Spin Chain
Lei Feng, Or Katz, Casey Haack +5
One-dimensional systems exhibiting a continuous symmetry can host quantum phases of matter with true long-range order only in the presence of sufficiently long-range interactions.…

Demonstration of three- and four-body interactions between trapped-ion spins
Or Katz, Lei Feng, Andrew Risinger +2
Quantum processors use the native interactions between effective spins to simulate Hamiltonians or execute quantum gates. In most processors, the native interactions are pairwise,…

Transition linewidth of cross-correlations in random intensity fluctuations in EIT
Lei Feng, Pengxiong Li, Mengzhen Zhang +2
It is known that cross-correlation between the random intensity fluctuations of two lasers forming electromagnetically-induced transparency (EIT) exhibits a transition from correla…
