Operator dynamics in Lindbladian SYK: a Krylov complexity perspective
Budhaditya Bhattacharjee, Pratik Nandy, Tanay Pathak
We use Krylov complexity to study operator growth in the -body dissipative SYK model, where the dissipation is modeled by linear and random -body Lindblad operators. In the l…
- Automated rational approximant for bi-variate series
Souvik Bera, Tanay Pathak
The Chisholm rational approximant is a natural generalization to two variables of the well-known single variable Padé approximant, and has the advantage of reducing to the latter w…
: Algebraic Relations for the Product of Propagators in Feynman integrals
B. Ananthanarayan, Souvik Bera, Tanay Pathak
Motivated by the foundational work of Tarasov, who pointed out that the algebraic relations of the type considered here can lead to functional reduction of Feynman integrals, we su…
Singularities of Feynman Integrals
Tanay Pathak, Ramesh Sreekantan
In this paper, we study the singularities of Feynman integrals using homological techniques. We analyse the Feynman integrals by compactifying the integration domain as well as the…
Closed Form Expressions for Certain Improper Integrals of Mathematical Physics
B. Ananthanarayan, Tanay Pathak, Kartik Sharma
We present new closed-form expressions for certain improper integrals of Mathematical Physics such as certain Ising, Box, and Associated integrals. The techniques we employ here in…
