Corrigendum: universal behaviour of domain wall meandering (2013 J. Phys.: Condens. Matter 25 205301)

Expressions (7) and 8) of ref. [1] are incorrect. The correct expressions (7) and (8) should read,
 
 <n^2>=(1+e^((-ε)⁄(k_B T)) )^2/(2(1-e^((-ε)⁄(k_B T)) )^2 ) a^2
 (7)
 and
 
 <n^2>=(1+e^(-□(T_c/T) ln⁡(3)) )^2/(2(1-e^(-□(T_c/T) ln⁡(3)) )^2 ) a^2
 
 (8)
 
 At the critical temperature, T_c, the mean square kink length of the triangular lattice should be 2a^2 and not 1a^2. The slope in Figure 5, i.e. □((<n^2>)⁄a)=2a, where a=0.5 nm is the lattice constant of the (√3 x√3)R〖30〗^o lattice of the decanethiol self-assembled monolayer on the Au(111) substrate, remains unaltered (slope is ~ 1 nm) and therefore our conclusions remain valid.&#13.
