Phase-Space Topology in a Single-Atom Synthetic Dimension
Kyungmin Lee, Sunkyu Yu, Jiyong Kang +5
We investigate topological features in the synthetic Fock-state lattice (FSL) of a single-atom system described by the quantum Rabi model. By diagonalizing the Hamiltonian, we iden…

Radio-Frequency Pseudo-Null Induced by Light in an Ion Trap
Daun Chung, Yonghwan Cha, Hosung Shon +12
In a linear radio-frequency (rf) ion trap, the rf null is the point of zero electric field in the dynamic trapping potential where the ion motion is approximately harmonic. When di…
