Relation between broadcast domination and multipacking numbers on chordal and other hyperbolic graphs
Sandip Das, Florent Foucaud, Sk Samim Islam +1
For a graph with a vertex set and an edge set , a function is called a \emph{broadcast} on . For e…
Dynamical analysis of coupled curvature-matter scenario in viable dark energy models at de Sitter phase
Anirban Chatterjee
We explore the interaction between dark matter and curvature-driven dark energy within viable gravity models, employing the phase-space analysis approach of linear stability…
Heavy quark dynamics via Gribov-Zwanziger approach
Sumit, Arghya Mukherjee, Najmul Haque +1
In this work, we investigate the momentum-dependent drag and diffusion coefficient of heavy quarks (HQs) moving in the quark-gluon plasma (QGP) background. The leading order scatte…
Multiple quantum Mpemba effect: exceptional points and oscillations
Amit Kumar Chatterjee, Satoshi Takada, Hisao Hayakawa
We explore the role of exceptional points and complex eigenvalues on the occurrence of the quantum Mpemba effect. To this end, we study a two-level driven dissipative system subjec…
Dynamics of viable dark energy models in the presence of Curvature-Matter interactions
Anirban Chatterjee, Rahul Roy, Sayantan Dey +1
In this study, we analyze the dynamics of the interaction between dark matter and curvature-driven dark energy in viable gravity models using the framework of dynamical syst…
Evading no-go for PBH formation and production of SIGWs using Multiple Sharp Transitions in EFT of single field inflation
Gourab Bhattacharya, Sayantan Choudhury, Kritartha Dey +3
Deploying \textit{multiple sharp transitions} (MSTs) under a unified framework, we investigate the formation of Primordial Black Holes (PBHs) and the production of Scalar Induced G…
Phenomenological profile of scotogenic fermionic dark matter
Anirban Karan, Soumya Sadhukhan, José W. F. Valle
We consider the possibility that neutrino masses arise from the exchange of dark matter states. We examine in detail the phenomenology of fermionic dark matter in the singlet-tripl…
Pulsating strings in I-brane background
Sagar Biswas, Nibedita Padhi, Kamal L Panigrahi
We study pulsating strings both on a single stack of NS5-branes and two orthogonal stacks of NS5-branes (the so called I-brane) by using the Polyakov form of the fundamental string…
Superconducting Gap Structure of Filled Skutterudite LaOsAs Compound through SR Investigations
A. Bhattacharyya, D. T. Adroja, A. D. Hillier +1
Filled skutterudite compounds have gained attention recently as an innovative platforms for studying intriguing low-temperature superconducting properties. Regarding the symmetry o…
Electric field induced Mott-insulator to metal transition and memristive behaviour in epitaxial VO thin film
Binoy Krishna De, V. G. Sathe, S. B. Roy
We report an isothermal electric field-induced first-order phase transition from Mott-insulator to the metallic state in the epitaxial thin film of VO in the temperature re…
Electroosmotic flow of a rheological fluid in non-uniform micro-vessels
S. Maiti, S. K. Pandey, J. C. Misra
The paper deals with a theoretical study of electrokinetic flow of a rheological Herschel-Bulkley fluid through a cylindrical tube of variable cross-section. The concern of this st…
Large sieve inequalities with power moduli and Waring's problem
Stephan Baier, Sean B. Lynch
We improve the large sieve inequality with th-power moduli, for all . Our method relates these inequalities to a restricted variant of Waring's problem. Firstly, we inpu…
Symmetries of Minkowski space-time: A possibility of exotic momentum space geometry?
Partha Nandi, Anwesha Chakraborty, Sayan Kumar Pal +2
The quest for a quantum gravity phenomenology has inspired a quantum notion of space-time, which motivates us to study the fate of the relativistic symmetries of a particular model…
Relativistic BGK hydrodynamics
Pracheta Singha, Samapan Bhadury, Arghya Mukherjee +1
Bhatnagar-Gross-Krook (BGK) collision kernel is employed in the Boltzmann equation to formulate relativistic dissipative hydrodynamics. In this formulation, we find that there rema…
