&lt;p&gt;This post discusses how phase equilibrium is established.  In particular, we discuss multi-component saturating systems which spontaneously form droplets at zero temperature. This was specifically motivated by the discussion of the conditions for droplet formation in Bose-Fermi mixtures &lt;a href="https://arxiv.org/abs/1801.00346"&gt;1801.00346&lt;/a&gt; and &lt;a href="https://arxiv.org/abs/1804.03278"&gt;1804.03278&lt;/a&gt;.  Specifically, the following conditions in &lt;a href="https://arxiv.org/abs/1804.03278"&gt;1804.03278&lt;/a&gt;:&lt;/p&gt;

39
Colloquially this means that if you are on a train, there is no experiment you can do to tell that the train is moving (without looking outside).&lt;/p&gt;

&lt;p&gt;This post will explain formally what Galilean covariance means, clarify the difference between covariance and invariance, and elucidate the meaning of Galilean covariance in classical and quantum mechanics.  In particular, it will explain the following result obtained by simply changing coordinates, which may appear paradoxical at first:&lt;/p&gt;
41
&lt;blockquote&gt;
42
&lt;p&gt;Consider a modern Lagrangian formulation of a classical object moving without a potential in 1D with coordinates $x$ and $\dot{x}$, and the same object in a moving frame with coordinates $X = x - vt$ and $\dot{X} = \dot{x} - v$.  The Lagrangian and conjugate momenta in these frames are:&lt;/p&gt;
43
&lt;p&gt;\begin{align}&lt;/p&gt;
44
&lt;/blockquote&gt;
45
&lt;p&gt;L[x, \dot{x}, t] &amp;amp;= \frac{m\dot{x}^2}{2}, &amp;amp;
46
   p &amp;amp;\equiv \pdiff{L}{\dot{x}} = m\dot{x},\
47
   L_v[X, \dot{X}, t] &amp;amp;= \frac{m(\dot{X}+v)^2}{2}, &amp;amp;
48
   P &amp;amp;\equiv \pdiff{L_v}{\dot{X}} = m(\dot{X}+v) = p.
49
  \end{align}&lt;/p&gt;
50
&lt;blockquote&gt;
51
&lt;p&gt;Perhaps surprisingly the conjugate momentum $P$ is the same in the moving frame whereas Galilean invariance implies that one should have a description in terms of $P = m\dot{X} = p - mv$.  The later description exists, but requires a somewhat non-intuitive addition to the Lagrangian of a total derivative.&lt;/p&gt;
52
&lt;/blockquote&gt;
