Probing Bloch oscillations using a slow-light sensor

Pei-Chen Kuan, Chang Huang and Shau-Yu Lan ORCID logo


We implement slow-light under electromagnetically induced transparency condition to measure the motion of cold atoms in an optical lattice undergoing Bloch oscillation. The motion of atoms is mapped out through the phase shift of light without perturbing the external and internal state of the atoms. Our results can be used to construct a continuous motional sensor of cold atoms.
