Low-temperature expansion of the Casimir-Polder free energy for an atom interacting with a conductive plane

Abstract

© 2019 World Scientific Publishing Company. The low-temperature expansion of the free energy of an atom/plane system is considered for a general symmetric form of the tensor conductivity of the plane. It is shown that the first correction is proportional to the second order of the temperature ∼ T 2 and comes from the TM mode. The agreement of the expansion and exact expressions for different models of conductivity is numerically demonstrated.
