Surprises with Nonrelativistic Naturalness
  We explore the landscape of technical naturalness for nonrelativistic
systems, finding surprises which challenge and enrich our relativistic
intuition already in the simplest case of a single scalar field. While the
immediate applications are expected in condensed matter and perhaps in
cosmology, the study is motivated by the leading puzzles of fundamental physics
involving gravity: The cosmological constant problem and the Higgs mass
hierarchy problem.
