Casimir interactions from infinite range and dilation symmetry

Venkat Abhignan, R. Sankaranarayanan

The Casimir interaction energy for a class of discrete self-similar configuration of parallel plates is evaluated using existing methods. The similarities to characteristics of an…

Continued functions and perturbation series: Simple tools for convergence of diverging series in $O (n)$ -symmetric $ϕ^{4}$ field theory at weak coupling limit

Venkat Abhignan, R. Sankaranarayanan

We determine universal critical exponents that describe the continuous phase transitions in different dimensions of space. We use continued functions without any external unknown p…
