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…

Effects of intrinsic decoherence on discord-like correlation measures of two-qubit spin squeezing model
Venkat Abhignan, R. Muthuganesan
Quantum decoherence happens when the system interacts with the environment. Quantum correlation behaviours in the two-qubit spin squeezing model are studied under the influence of…

Continued functions and critical exponents: Tools for analytical continuation of divergent expressions in phase transition studies
Venkat Abhignan, R. Sankaranarayanan
Resummation methods using continued functions are implemented to converge divergent series appearing in perturbation problems related to continuous phase transitions in field theor…
