Measurement of Casimir-Polder interaction for slow atoms through a material grating
We present a method utilizing atomic diffraction patterns and statistical analysis tools to infer the Casimir-Polder interaction between argon atoms and a silicon nitride nanograting. The quantum model that supports the data is investigated in detail, as are the roles of nanograting geometry, finite...

| description | We present a method utilizing atomic diffraction patterns and statistical analysis tools to infer the Casimir-Polder interaction between argon atoms and a silicon nitride nanograting. The quantum model that supports the data is investigated in detail, as are the roles of nanograting geometry, finite-size effects, slit width opening angles, Lennard-Jones potentials, and patch potentials. Our findings indicate that the atom-surface potential strength parameter is C_{3}=6.9±1.2meVnm^{3}. This value is primarily constrained by the knowledge of the nanograting geometry. The high sensitivity of our method paves the way for precise determination of the Casimir-Polder potential and exploration of new short-distance forces. |
