One-loop quantum effects in Carroll scalars
Carrollian field theories at the classical level possess an infinite number of space-time
symmetries, namely the supertranslations. In this article, we inquire whether these …

Instantons in theories: Transseries, virial theorems, and numerical aspects
We discuss numerical aspects of instantons in two-and three-dimensional ϕ 4 theories with
an internal O (N) symmetry group, the so-called N-vector model. By combining asymptotic …

[PDF][PDF] A Serendipitous Journey through Stochastic Processes
LT Giorgini - 2021 - diva-portal.org
A stochastic process refers to a system that evolves in time under the influence of chance
fluctuations. The random nature of such a process makes impossible the exact prediction of …
