......@@ -20,7 +20,7 @@ We recall that the electric permittivity is :math:`\epsilon_0` for vacuum, and
a background and a relative term :math:`\epsilon/\epsilon_0=\epsilon_b\epsilon_r`.
The background is constant and uniform, whereas the explicit term is due to
dynamic microscopic objects (dimers in this case) which carry a charge dipole
moment. The strength of elecrostatic interactions in a background is set by the bare Bjerrum length :math:`l_B=e^2/(4
moment. The strength of electrostatic interactions in a background is set by the bare Bjerrum length :math:`l_B=e^2/(4
\pi\epsilon_0 \epsilon_b k_BT)`. On the other hand, from linear response theory, the bulk value of the relative permittivity is
:math:`\epsilon_r = 1 + \frac{\langle\vec{P}^2\rangle_{\vec{E}=\vec{0}}}{3\epsilon_0\epsilon_{b}\, k_BT\,V}`,
where tin-foil boundary conditions are assumed.
