Query: Quantum effects due to a moving Dirichlet point   We study quantum effects induced by a point-like object that imposes
Dirichlet boundary conditions along its world-line, on a real scalar field
$\varphi$ in 1, 2 and 3 spatial dimensions. The boundary conditions result from
the strong coupling limit of a term quadratic in the field and localized on the
particle's trajectory. We discuss the renormalization issues that appear and
evaluate the effective action. Special attention is paid to the case of 2
spatial dimensions where the coupling constant is adimensional.
