Relating the curvature of De Sitter universe to open quantum lamb shift spectroscopy

Swain, Abinash et al. (Springer, 2021-02)

In this paper, we explore the connection between the curvature of the background De Sitter space-time with the spectroscopic study of entanglement of two atoms. Our set up is in the context of an Open Quantum System (OQS), ...
Readout of quasiperiodic systems using qubits

Saha, Madhumita; Agarwalla, Bijay Kumar; Venkatesh, B. Prasanna (American Physical Society, 2021-02)

We develop a theoretical scheme to perform a readout of the properties of a quasiperiodic system by coupling it to one or two qubits. We show that the decoherence dynamics of a single qubit coupled via a pure dephasing ...
The multi-faceted inverted harmonic oscillator: Chaos and complexity

Bhattacharyya, Arpan; Chemissany, Wissam; Haque, S. Shajidul; Murugan, Jeff; Yan, Bin (SciPost, 2021-02)

The harmonic oscillator is the paragon of physical models; conceptually and computationally simple, yet rich enough to teach us about physics on scales that span classical mechanics to quantum field theory. This multifaceted ...
Magnetohydrodynamics model of an X-class flare in NOAA active region 12017 initiated with non-force-free extrapolation

Nayak, Sushree Sangeeta; Bhattacharyya, Ramit; Kumar, Sanjay (American Institute of Physics, 2021-02)

We present a three-dimensional magnetohydrodynamic simulation of the NOAA active region 12017 to explore the onset of an X-class flare on 2014 March 29 at 17:48 UT. The simulation is initiated with a magnetic field constructed ...
Dynamics of the creation of a rotating Bose Einstein condensation by two photon Raman transition using a Laguerre Gaussian laser pulse

Mukherjee, Koushik; Bandyopadhyay, Soumik; Angom, Dilip; Martin, Andrew M.; Majumder, Sonjoy (MDPI, 2021-02)

We present numerical simulations to unravel the dynamics associated with the creation of a vortex in a Bose–Einstein condensate (BEC), from another nonrotating BEC using two-photon Raman transition with Gaussian (G) and ...
Dynamics of QCD matter-current status

Chandra, Vinod; Kumar, Deepak; Kurian, Manu et al. (World Scientific Publishing, 2021-02)

In this article, there are 18 sections discussing various current topics in the field of relativistic heavy-ion collisions and related phenomena, which will serve as a snapshot of the current state of the art. Section 1 ...
Activity of the first interstellar comet 2I/Borisov around perihelion: results from Indian observatories

Aravind, K. et al. (Oxford University Press, 2021-02)

Comet 2I/Borisov is the first true interstellar comet discovered. Here, we present results from observational programs at two Indian observatories, 2 m Himalayan Chandra Telescope at the Indian Astronomical Observatory, ...
