Understanding Syllogistic Reasoning in LLMs from Formal and Natural Language Perspectives
Aheli Poddar, Saptarshi Sahoo, Sujata Ghosh
We study syllogistic reasoning in LLMs from the logical and natural language perspectives. In process, we explore fundamental reasoning capabilities of the LLMs and the direction t…
AFarePart: Accuracy-aware Fault-resilient Partitioner for DNN Edge Accelerators
Mukta Debnath, Krishnendu Guha, Debasri Saha +2
Deep Neural Networks (DNNs) are increasingly deployed across distributed and resource-constrained platforms, such as System-on-Chip (SoC) accelerators and edge-cloud systems. DNNs…
Relations Among Different Inequality Measures in Complex Systems: From Kinetic Exchange to Earthquake Models
Shohini Sen, Suchismita Banerjee, Bikas K Chakrabarti
We present a numerical study of several inequality measures across two kinetic wealth exchange models with extreme inequality features (namely the Banerjee model, and the Chakrabor…
Exact and mean-field analysis of the role of Hubbard interactions on flux driven circular current in a quantum ring
Rahul Samanta, Santanu K. Maiti, Shreekantha Sil
We investigate circular current in both ordered and disordered Hubbard quantum rings threaded by magnetic flux, employing exact diagonalization and the Hartree-Fock mean-field appr…
Relations Between the Inequality Indices Gini, Pietra and Kolkata: Theory and Data Analysis
Asim Ghosh, Bikas K. Chakrabarti
We study relations between three inequality indices, namely the Gini (), Pietra () and Kolkata () introduced in 1912, 1915 and 2014 respectively and all are derived from t…
Are Large Random Graphs Always Safe to Hide?
Sourav Chakraborty, Sujata Ghosh, Smiha Samanta
We discuss winning possibilities of players in various variants of cops and robber game played on large random graphs, a testbed for various kinds of network queries, search proble…
Bayesian Variable Selection for Censored Spatial Responses with Application to PFAS Concentrations in California
Suman Majumder, Indranil Sahoo
Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants of major public health concern due to their resistance to degradation, widespread presence, and p…
Design Stability in Adaptive Experiments: Implications for Treatment Effect Estimation
Saikat Sengupta, Koulik Khamaru, Suvrojit Ghosh +1
We study the problem of estimating the average treatment effect (ATE) under sequentially adaptive treatment assignment mechanisms. In contrast to classical completely randomized de…
Exploring the Co-SIMP dark matter model using the 21-cm signal from the dark ages
Debarun Paul, Sourav Pal, Deepthi Moorkanat +3
The redshifted 21-cm signal from the dark ages offers a powerful probe of cosmological models and the underlying dark matter (DM) microphysics. We investigate deviations from the s…
New perspective on symmetry breaking in a clean antiferromagnetic chain: Spin-selective transport and NDR phenomenon
Prabhab Patra, Santanu K. Maiti
The primary requirement for achieving spin-selective electron transfer in a nanojunction possessing a magnetic system with zero net magnetization is to break the symmetry between t…
Null reduction and dynamical realization of Carrollian conformal symmetries
Ashis Saha, Rabin Banerjee, Sunandan Gangopadhyay
We start from a Lorentzian action in a deformed light-cone background and applying the method of null reduction leads to a Carrollian action in one lower spacetime dimensions. We a…
Heterotic Warm Inflation
Arjun Berera, Heliudson Bernardo, Suddhasattwa Brahma +3
We propose a two-field model of warm inflation motivated by a heterotic string construction, involving an axion and a dilaton-like scalar field with non-trivial kinetic mixing. Gau…
Persistent Charge and Spin Currents in a Ferromagnetic Hatano-Nelson Ring
Sourav Karmakar, Sudin Ganguly, Santanu K. Maiti
We investigate persistent charge and spin currents in a ferromagnetic Hatano-Nelson ring with anti-Hermitian intradimer hopping, where non-reciprocal hopping generates a synthetic…
Dimension Agnostic Testing of Survey Data Credibility through the Lens of Regression
Debabrota Basu, Sourav Chakraborty, Debarshi Chanda +3
Assessing whether a sample survey credibly represents the population is a critical question for ensuring the validity of downstream research. Generally, this problem reduces to est…
Tracing Signatures of Modified Gravity in Redshift-Space Galaxy Bispectrum Multipoles: Prospects for Euclid
Sourav Pal, Debanjan Sarkar, Alejandro Aviles
We study the galaxy bispectrum multipoles in the Hu-Sawicki gravity model, where a scalar degree of freedom mediates a fifth force that is screened in high-density environme…
Teleportation Fidelity of Binary Tree Quantum Repeater Networks
Soumit Roy, Md Rahil Miraj, Chittaranjan Hens +3
Binary tree network, being a subclass of Cayley tree network, is a significant topological structure used for information transfer in a hierarchical sense. In this article, we cons…
Is Dark Energy an Effective Manifestation of Non-equilibrium Thermodynamics? -- Insights from DESI
Sauvik Bhattacharjee, Sudip Halder, Jaume de Haro +2
We investigate the background cosmological expansion on the onset of cosmological homogeneous matter creation scenario, a dynamical dark matter approach (), and…
KisMATH: Do LLMs Have Knowledge of Implicit Structures in Mathematical Reasoning?
Soumadeep Saha, Akshay Chaturvedi, Saptarshi Saha +2
Chain-of-thought (CoT) traces have been shown to improve performance of large language models on a plethora of reasoning tasks, yet there is no consensus on the mechanism by which…
Twisting inflation to sub-Planckian axion decay constants
Peter Adshead, Suddhasattwa Brahma, Indranil Das
