We investigate the electronic structure and magnetic properties of the distorted honeycomb lattice compound KCuInP2O8 through a combination of experimental measurements, first prin…
Fluctuation-stable generalized entropy probes of spectral heterogeneity
Arpita Goswami
Generalized entropy measures are widely used to characterize localization and multifractality, and the regime \(q>1\) is often empirically found to exhibit improved numerical stabi…
Quantum-to-semiclassical Husimi dynamics of non-Hermitian localization transitions
Pallabi Chatterjee, Bhabani Prasad Mandal, Ranjan Modak
The localization transition in the Hermitian Aubry-André model is known to have a clear classical origin, with the critical point being exactly predictable from an analysis of clas…
A FUV-optical approach for studying hierarchical star formation in nearby galaxies with UVIT
Sanal Ananthu, Gairola Shashank, Smitha Subramanian +4
Young star-forming clumps (SFCs) emit strongly in the ultraviolet (UV), making UV imaging ideal for detecting them. The Ultraviolet Imaging Telescope (UVIT) onboard AstroSat, with…
Analogs of absolutely maximally entangled states in nonlocal correlations via the sheaf-theoretic framework and its applications
Nripendra Majumdar, S. Aravinda
The foundational work by Bell led to an interest in understanding non-local correlations that arise from entangled states shared between distinct, spacelike-separated parties, whic…
Tuning Magnetic and Electronic Properties of Double Perovskite LaCoIrTiO
Sromona Nandi, Vineeta Yadav, Sheetal +5
The LaCoIrTiO double perovskite series serves as an effective platform for investigating the evolution of magnetic and electronic properties as a function of ch…
ThirstyFLOPS: Water Footprint Modeling and Analysis Toward Sustainable HPC Systems
Yankai Jiang, Raghavendra Kanakagiri, Rohan Basu Roy +1
High-performance computing (HPC) systems are becoming increasingly water-intensive due to their reliance on water-based cooling and the energy used in power generation. However, th…
Study of low-energy electron-induced dissociation of 1-Propanol
Soumya Ghosh, Dipayan Chakraborty, Anirban Paul +1
The fragmentation of 1-propanol resulting from dissociative electron attachment has been explored across an energy range of 3.5 to 16 eV. Four distinct ion species are identified:…
Alz-QNet: A Quantum Regression Network for Studying Alzheimer's Gene Interactions
Debanjan Konar, Neerav Sreekumar, Richard Jiang +1
Understanding the molecular-level mechanisms underpinning Alzheimer's disease (AD) by studying crucial genes associated with the disease remains a challenge. Alzheimer's, being a m…
Favorable modifications of Scrape-Off Layer (SOL) heat flux width through pulsed fuelling in ADITYA-U Tokamak
SK Injamul Hoque, Harshita Raj, Ritu Dey +19
Enhancement of the scrape-off layer (SOL) heat flux width has been observed in the ADITYA-U Tokamak following the injection of short fuel gas pulses. A notable reduction in paralle…
Reconstructing galactic feedback history via the Lyman- forest with Habitable Worlds Observatory
Megan T. Tillman, Joseph N. Burchett, Blakesley Burkhart +2
Recent studies have focused on the low- Ly forest as a potential constraint on galactic feedback, as different AGN and stellar feedback models in hydrodynamic simulations pro…
Quantum thermalization and average entropy of a subsystem
Smitarani Mishra, Shaon Sahoo
Page's seminal result on the average von Neumann (VN) entropy does not immediately apply to realistic many-body systems which are restricted to physically relevant smaller subspace…
Entanglement structure for finite system under dual-unitary dynamics
Gaurav Rudra Malik, Rohit Kumar Shukla, Sudhanva Joshi +2
The dynamics of quantum many-body systems in the chaotic regime are of particular interest due to the associated phenomena of information scrambling and entanglement generation wit…
The JCMT BISTRO-3 Survey: Variation of magnetic field orientations on parsec and sub-parsec scales in the massive star-forming region G28.34+0.06
Jihye Hwang, Kate Pattle, Chang Won Lee +35
Magnetic fields play a significant role in star-forming processes on core to clump scales. We investigate magnetic field orientations and strengths in the massive star-forming clum…
ForgetMeNot: Understanding and Modeling the Impact of Forever Chemicals Toward Sustainable Large-Scale Computing
Rohan Basu Roy, Raghavendra Kanakagiri, Yankai Jiang +1
Fluorinated compounds, often referred to as forever chemicals, are critical in various steps of semiconductor fabrication like lithography, etching, chamber cleaning, and others. F…
Characterizing quantum dynamics using multipartite entanglement generation
Gaurav Rudra Malik, Rohit Kumar Shukla, S. Aravinda +1
Entanglement is a defining feature of many-body quantum systems and is an essential requirement for quantum computing. It is therefore useful to study physical processes which gene…
Subsystem localization in a two-leg ladder system
Arpita Goswami, Pallabi Chatterjee, Ranjan Modak +1
We consider a ladder system where one leg, referred to as the ``bath", is governed by an Aubry-André (AA) type Hamiltonian, while the other leg, termed the ``subsystem", follows a…
Emergence of Hermitian topology from non-Hermitian knots
Gaurav Hajong, Ranjan Modak, Bhabani Prasad Mandal
The non-Hermiticity of the system gives rise to a distinct knot topology in the complex eigenvalue spectrum, which has no counterpart in Hermitian systems. In contrast, the singula…
