Extrapolation from hypergeometric functions, continued functions and Borel-Leroy transformation; Resummation of perturbative renormalization functions from field theories
Venkat Abhignan
Physically relevant field-theoretic quantities are usually derived from perturbation techniques. These quantities are solved in the form of an asymptotic series in powers of small…

Continued functions and Borel-Leroy transformation: Resummation of six-loop ε-expansions from different universality classes
Venkat Abhignan, R. Sankaranarayanan
We handle divergent ε expansions in different universality classes derived from modified Landau-Wilson Hamiltonian. Landau-Wilson Hamiltonian can cater for describing critical phen…

Casimir-like effect from thermal field fluctuations
Venkat Abhignan, R. Sankaranarayanan
Landau-Ginzburg field theory is usually applied to systems for understanding continuous phase transitions at critical points. Here we analyze the thermal field using a simila…
