Query: Dynamical Casimir effect and minimal temperature in quantum
  thermodynamics   We study the fundamental limitations of cooling to absolute zero for a qubit,
interacting with a single mode of the electromagnetic field. Our results show
that the dynamical Casimir effect, which is unavoidable in any finite-time
thermodynamic cycle, forbids the attainability of the absolute zero of
temperature, even in the limit of an infinite number of cycles.
