Classical and Quantum cosmology for two scalar field Brans-Dicke type theory: A Noether Symmetry approach

Shriton Hembrom, Roshni Bhaumik, Sourav Dutta +1

The paper deals with a cosmological model containing two scalar fields which can be considered as an extension of the Brans-Dicke scalar field model. Due to highly coupled non line…

A description of classical and quantum cosmology for a single scalar field torsion gravity

Dipankar Laya, Roshni Bhaumik, Sourav Dutta +1

In the background of homogeneous and isotropic flat FLRW space-time, both classical and quantum cosmology has been studied for teleparallel dark energy (DE) model. Using Noether sy…

Quantum Cosmology in Coupled Brans-Dicke Gravity: A Noether Symmetry Analysis

Dipankar Laya, Sourav Dutta, Subenoy Chakraborty

The present work deals with a multi-field cosmological model in a spatially flat FLRW space-time geometry. The usual Brans-Dicke(BD) field and another scalar field are minimally co…

Late time dynamics in SUSY saddle-dominated scrambling through higher-point OTOC

Rathindra Nath Das, Sourav Dutta, Archana Maji

In this article, we study the scrambling dynamics in supersymmetric quantum mechanical systems. The eigenstate representation of such supersymmetric systems allows us to present an…
