Observation of quantum interference of optical transition pathways in Doppler-free two-photon spectroscopy and implications for precision measurements
Bubai Rahaman, Sid C. Wright, Sourav Dutta
Doppler-free two-photon spectroscopy is a standard technique for precision measurement of transition frequencies of dipole-forbidden transitions. The accuracy of such measurements…
Classical and quantum cosmology in -gravity theory: A Noether symmetry approach
Roshni Bhaumik, Sourav Dutta, Subenoy Chakraborty
In the framework of -gravity theory, classical and quantum cosmology has been studied in the present work for FLRW space-time model. The Noether symmetry, a point-like symmet…
A stable 671 nm external cavity diode laser with output power exceeding 150 mW suitable for laser cooling of lithium atoms
Sourav Dutta, Bubai Rahaman
We report the design and performance of a Littrow-type 671 nm External Cavity Diode Laser (ECDL) that delivers output power greater than 150 mW and features enhanced passive stabil…
High precision measurement of the hyperfine splitting and ac Stark shift of the state in atomic cesium
Bubai Rahaman, Sourav Dutta
We report the measurement of hyperfine splitting in the state of Cs using high resolution Doppler-free two-photon spectroscopy in a Cs vapor cell. We det…
Static spherically symmetric wormhole with quadratic shape function and particle trajectories around it
Bikram Ghosh, Sourav Dutta, Sudeshna Mukerji +1
The paper deals with static traversable wormhole having shape function a polynomial of the radial coordinate of degree 2. Embedding of the wormholes in space-time is examined both…
Data-driven reduced order modeling of environmental hydrodynamics using deep autoencoders and neural ODEs
Sourav Dutta, Peter Rivera-Casillas, Orie M. Cecil +3
Model reduction for fluid flow simulation continues to be of great interest across a number of scientific and engineering fields. In a previous work [arXiv:2104.13962], we explored…
