Closed-Form Solutions of Zero Dimensional $ϕ^{4}$ -Field Theory Using Bessel Functions: A Non-Perturbative Approach

Ranjiva M. Munasinghe

The integral $\int_{- \infty}^{\infty} e^{- x^{2} - g x^{4}} d x$ is used as an introductory learning tool in the study of Quantum Field Theory and path integrals. Typically it is analy…

Revisiting Feller Diffusion: Derivation and Simulation

Ranjiva Munasinghe, Leslie Kanthan, Pathum Kossinna

We propose a simpler derivation of the probability density function of Feller Diffusion using the Fourier Transform and solving the resulting equation via the Method of Characteris…

Multi-Scaling of Correlation Functions in Single Species Reaction-Diffusion Systems

Ranjiva M. Munasinghe, R. Rajesh, Oleg V. Zaboronski

We derive the multi-fractal scaling of probability distributions of multi-particle configurations for the binary reaction-diffusion system $A + A \to \emptyset$ in $d \leq 2$ and for…
