Query: Unified Description of Macroscopic Quantum Forces   We introduce a unified description of Casimir and Casimir-Polder forces
between classical objects in quantum field theory (QFT). We focus on
interactions mediated by a scalar field. We first show that the quantum work
felt by an arbitrary (either rigid or deformable) classical body is finite upon
requiring conservation of matter. Using our formulation, we explicitly show how
the complete QFT prediction for the quantum pressure inside the Dirichlet
sphere is finite, thereby solving a long-standing problem. We then show that
our general result interpolates between Casimir and Casimir-Polder forces for
arbitrary rigid bodies. We provide the expressions for the generalised Casimir
force in the simple cases of plate-plate and plate-point geometries. In the
latter geometry, we show how to compute phase shifts observable in atomic
interferometry, induced by the generalized quantum force.
