Towards efficient quantum memory of orbital angular momentum qubits in cold atoms
Chengyuan Wang, Ya Yu, Yun Chen +7
The spatial modes of light, carrying a quantized amount of orbital angular momentum (OAM), is one of the excellent candidates that provides access to high-dimensional quantum state…
Diverse polarization angle swings from a repeating fast radio burst source
R. Luo, B. J. Wang, Y. P. Men +34
Fast radio bursts (FRBs) are millisecond-duration radio transients of unknown origin. Two possible mechanisms that could generate extremely coherent emission from FRBs invoke neutr…
Doubly Modulated Optical Lattice Clock Interference and Topology
Xiao-Tong Lu, Tao Wang, Ting Li +5
The quantum system under periodical modulation is the simplest path to understand the quantum non-equilibrium system, because it can be well described by the effective static Floqu…
Role of hyperfine interaction in Landé -factors of clock states
Tingxian Zhang, Benquan Lu, Jiguang Li +4
In the weak-magnetic-field approximation, we derived a general expression of hyperfine-induced Landé -factors. By using this formula and the multi-configuration Dirac-Hartree-Fo…
Rabi Spectroscopy and Sensitivity of a Floquet Engineered Optical Lattice Clock
Mo-Juan Yin, Tao Wang, Xiao-Tong Lu +6
We periodically modulate the lattice trapping potential of a Sr optical clock to Floquet engineer the clock transition. In the context of atomic gases in lattices, Floquet e…
Pulsar Timing Observations with Haoping Radio Telescope
Jintao Luo, Yuping Gao, Tinggao Yang +8
We report pulsar timing observations carried out in L-band with NTSC's 40-meter Haoping Radio Telescope (HRT), which was constructed in 2014. The observations were carried out usin…
