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…
Classical and Quantum Cosmology in Einstein-aether Scalar-tensor gravity: Noether Symmetry Analysis
Dipanakr Laya, Roshni Bhaumik, Sourav Dutta +1
The present work deals with Einstein-aether Scalar tensor gravity in the background of homogeneous and isotropic flat FLRW space-time model. The Noether symmetry vector identifies…
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…
Noether Symmetry analysis in Chameleon Field Cosmology
Roshni Bhaumik, Sourav Dutta, Subenoy Chakraborty
This work deals with chameleon field cosmology (a scalar field nonminimally coupled to cold dark matter) in the background of flat Friedmann-Lemaitre-Robertson-Walker (FLRW) space-…
Multiscalar field cosmological model and possible solutions using Noether symmetry approach
Santu Mondal, Roshni Bhaumik, Sourav Dutta +1
In this work, a cosmological model is considered having two scalar fields minimally coupled to gravity with a mixed kinetic term. The model is characterized by the coupling functio…
Hyperfine coupling constants of the cesium state measured up to the octupole term
Bubai Rahaman, Sourav Dutta
We report the measurement of the hyperfine splitting in the state of Cs using high resolution Doppler-free two-photon spectroscopy enabled by precise frequency s…
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…
