abstract = {The manipulation of ultracold atoms in radio-frequency 

 (RF)-dressed potentials offers unique advantages over static 

 magnetic traps, such as the ability to create more complex 

 potential landscapes, better control of atomic states, and 

 increased robustness to environmental noise. Among the 

 accessible geometries, ring traps are particularly promising for 

 atomic Sagnac interferometers, which can be used to measure 

 rotational motion with high sensitivity. Here, the authors 

 demonstrate the state-dependent transport of atoms in an 

 RF-dressed ring trap on an atom chip. By exploiting the 

 polarization-dependent coupling of RF fields to different atomic 

 hyperfine states, the authors achieve controlled transport of 

 atoms in opposite directions. This approach targets the 

 development of compact, high-precision devices for applications 

 in inertial navigation and rotation sensing.},
