Log-periodic behavior of finite size effects in field theories with RG limit cycles
A. LeClair, J. M. Roman, G. Sierra
We compute the finite size effects in the ground state energy, equivalently the effective central charge c_{eff}, based on S-matrix theories recently conjectured to describe a cycl…

Russian Doll Renormalization Group and Superconductivity
Andre LeClair, Jose Maria Roman, German Sierra
We show that an extension of the standard BCS Hamiltonian leads to an infinite number of condensates with different energy gaps and self-similar properties, described by a cyclic R…
