A Note on First Order Phase Transitions in the Continuum
We consider the Potts model in R d , d ≥ 2 , with q ≥ 3 states and prove that for all values of the inverse temperature β which are small enough there is a critical value z c ( β ) of the fugacity so that at ( β , z c ( β ) ) there are q + 1 extremal DLR measures (thus the phase transition is of fir...

Summary: | We consider the Potts model in
R
d
,
d
≥
2
, with
q
≥
3
states and prove that for all values of the inverse temperature
β
which are small enough there is a critical value
z
c
(
β
)
of the fugacity so that at
(
β
,
z
c
(
β
)
)
there are
q
+
1
extremal DLR measures (thus the phase transition is of first order). The first
q
have a spin which appears with higher frequency than the other spins while in the last one all the spins have the same frequency, moreover the particle density is strictly smaller than in the first
q
states. |
