Surface morphology and shear effect on lubricated granular system
Ravindra S. Ghodake, Ashish V. Orpe
Improving the particle surface frictional behavior is of considerable importance in several industries so as to manipulate the powder flowability and handling. In this work, we hav…
Moire-Engineered Excitonic Landscape and Phonon-Mediated Recombination in Twisted WSe2 Bilayers
Memansa Thapa, Aksa Thomas, Jayalekshmi U. J. +7
We report light emission from the moire superlattice of a twisted bilayer of tungsten diselenide (WSe2/WSe2) encapsulated in insulating hexagonal boron nitride (hBN). The low-tempe…
Subluminous Type IIP SN 2024abfl as a Result of a Significantly Low-energy Fe-core Collapse
Rishabh Singh Teja, D. K. Sahu, G. C. Anupama +7
We present extensive, well-sampled multiwavelength photometric and low-resolution optical spectroscopic observations of the low-luminosity Type IIP supernova SN 2024abfl. SN 2024ab…
Surface coating induced lubrication in flowing granular materials
Sayali V. Chaudhary, Ashish V. Orpe
We investigate the flow of spherical, bulk granular particles down an inclined plane mixed with small-sized spherical lubricant particles using discrete element method simulations.…
Type Iax supernovae as a source of iron-rich silicate dust
Aman Kumar, Arkaprabha Sarangi
We model the formation of dust in the ejecta of Type Iax supernovae (SNe), which is a low-luminosity subclass of Type Ia SNe. A non-equilibrium chemical kinetic approach is adopted…
Efficient algorithm for fidelity estimation of two quantum states
Anumita Mukhopadhyay, Shibdas Roy, Arun Kumar Pati
The fidelity estimation between two quantum states is crucial for quantum computation and information science. However, an efficacious method for this, especially for mixed states…
SinLlama -- A Large Language Model for Sinhala
H. W. K. Aravinda, Rashad Sirajudeen, Samith Karunathilake +3
Low-resource languages such as Sinhala are often overlooked by open-source Large Language Models (LLMs). In this research, we extend an existing multilingual LLM (Llama-3-8B) to be…
Universal Coacting Hopf Algebra of a finite-dimensional Algebra over an Operad
Saikat Goswami, Satyendra Kumar Mishra, Suman Pattanayak
A. L. Agore and G. Militaru constructed a new invariant (a ``universal coacting Hopf algebra") for some finite-dimensional binary quadratic algebras such as Lie/Leibniz algebras, a…
An Efficient Hardware Implementation of Elliptic Curve Point Multiplication over on FPGA
Ruby Kumari, Tapas Rout, Babul Saini +2
Elliptic Curve Cryptography (ECC) is widely accepted for ensuring secure data exchange between resource-limited IoT devices. The National Institute of Standards and Technology (NIS…
Universal Coacting Hopf algebra of a Finite dimensional Lie-Yamaguti algebra
Saikat Goswami, Satyendra Kumar Mishra, Goutam Mukherjee
M. E. Sweedler first constructed a universal Hopf algebra of an algebra. It is known that the dual notions to the existing ones play a dominant role in Hopf algebra theory. Yu. I.…
Structure-Dynamics Correlation and Its Link to Fragility and Dynamic Heterogeneity
Mohit Sharma, Srikanth Sastry, Sarika Maitra Bhattacharyya
Understanding the connection between structure, dynamics, and fragility, the rate at which the relaxation time grows with decreasing temperature, is central to unravelling the glas…
Self-Assembly of Delta-Formamidinium Lead Iodide Nanoparticles to Nanorods: Study of Memristor Properties and Resistive Switching Mechanism
Chinnadurai Muthu, A. N. Resmi, Avija Ajayakumar +5
In the quest for advanced memristor technologies, this study introduces the synthesis of delta-formamidinium lead iodide nanoparticles and their self-assembly into nanorods.
Cancellation of a critical pair in discrete Morse theory and its effect on (co)boundary operators
Anupam Mondal, Sajal Mukherjee, Pritam Chandra Pramanik
Discrete Morse theory helps us compute the homology groups of simplicial complexes in an efficient manner. A "good" gradient vector field reduces the number of critical simplices,…
Transition Metal-Driven Variations in Structure, Magnetism, and Photocatalysis of Monoclinic M3Se4 (M = Fe, Co, Ni) Nanoparticles
Monika Ghalawat, Inderjeet Chauhan, Dinesh Singh +2
The transition metal selenides (MxSey) have gained attention for their unique physical and chemical properties, especially those associated with the transition metal (M). Despite a…
Interplay between superconducting fluctuations and weak localization in disordered TiN thin films
Sachin Yadav, Bikash Gajar, R. P. Aloysius +1
The interplay between superconducting fluctuations (SFs) and weak localization (WL) has been probed by temperature dependent resistance [R(T)] and magnetoresistance (MR) measuremen…
