In this paper particle creation is extended to a dissipative massless scalar field in 1+1 dimension satisfying a Robin boundary condition (BC) at a non-relativistic moving boundary. For this purpose we define a Lagrangian for scalar field and then constitutive equations for the scalar field and medium are obtained as the Euler-Lagrange equations using the Lagrangian of a total system. We derive input and output bosonic field operators. This allows us to calculate the spectral distribution of created particles. In addition we applied our result for particle creation in presence of medium. We will see in the presence of medium Dirichlet and Neumann BC do not have same spectrum.
Keywords: particle creation, dissipative massless scalar field, Robin boundary condition (BC), Bogoliubov transformation
