  In this work we present results of the long-range electromagnetic
Casimir-Polder interactions between two neutrons, a neutron and a conducting
wall, and a neutron between two walls. As input, we use the dynamic dipole
polarizabilities of the neutron fitted to chiral EFT results up to the pion
production threshold and at the onset of the Delta resonance. Our work can be
relevant to the physics of confined ultracold neutrons inside bottles.
