1 Correction to: Eur. Phys. J. B (2013) 86:343 https://doi.org/10.1140/epjb/e2013-40551-y

Some equations in the paper F. Briscese, Eur. Phys. J. B (2013) 86: 343 have been corrected.

In eq. (10) there is a missing g in the definition of the function \(\theta \). The correct form of this equation is

$$\begin{aligned} \begin{array}{ll} d\varOmega \equiv dx\, dp\,x^2\,p^2; \varLambda \left[ \theta \right] \equiv \left[ \exp {\left[ \theta \right] }-1\right] ^{-1};\\ \\ \theta \equiv \frac{\epsilon (p,x)+ 2 \,g\, \bar{n}(x,g)}{k_B T_c(g)}; \bar{n}(x,g) \equiv n(x,g)-n(0,g). \end{array} \end{aligned}$$
(1)

In eq. (23) the term \(\partial _g \theta \) must be replaced by \(\partial ^2_g \theta \). The correct form of this equation is:

$$\begin{aligned} \int d\varOmega \{ \varLambda '\left[ \theta \right] \partial ^2_g \theta +\varLambda ''\left[ \theta \right] \left( \partial _g \theta \right) ^2 \} = 0 . \end{aligned}$$
(2)

Equation (30) must be replaced by

$$\begin{aligned} S\left[ -V(x)/k_B T_c\right] \simeq 4\pi + \sqrt{\pi V/k_B T_c}(6\zeta [1/2]-2 I_1), \end{aligned}$$
(3)

where a \(4\zeta [1/2]\) term has been replaced by \(6\zeta [1/2]\).
