Query: Universal scaling in first-order phase transitions mixed with nucleation
  and growth   Matter exhibits phases and their transitions. These transitions are
classified as first-order phase transitions (FOPTs) and continuous ones. While
the latter has a well-established theory of the renormalization group, the
former is only qualitatively accounted for by classical theories of nucleation,
since their predictions often disagree with experiments by orders of magnitude.
A theory to integrate FOPTs into the framework of the renormalization-group
theory has been proposed but seems to contradict with extant wisdom and lacks
numerical evidence. Here we show that universal hysteresis scaling as predicted
by the renormalization-group theory emerges unambiguously when the theory is
combined intimately with the theory of nucleation and growth in the FOPTs of
the paradigmatic two-dimensional Ising model driven by a linearly varying
externally applied field below its critical point. This not only provides a new
method to rectify the nucleation theories, but also unifies the theories for
both classes of transitions and FOPTs can be studied using universality and
scaling similar to their continuous counterpart.
