Multi-Lepton Probes of the Drell-Yan Production of Triplet Higgses
Siddharth P. Maharathy, Srimoy Bhattacharya, Andreas Crivellin +3
Excesses in di-photon, , and spectra indicate the existence of a new Higgs boson with mass GeV. However, no excess is observed in the channel. This patter…
Voltage-Regulated Photoluminescence Modulation in a 0D-2D Mixed Dimensional Heterostructure
S. V. U. Vedhanth, Amit Bhunia, Mohit Kumar Singh +3
Bias dependent oscillations in excitonic photoluminescence are observed in a mixed dimensional 0D 2D heterostructure. These oscillations arise from modulation by oscillatory DC pho…
Exciton-Selective Phonon Coupling in a Lead Halide Perovskite
Pradeepa H. L., Sagnik Chatterjee, Sayantan Patra +6
Exciton-phonon interactions govern the optical response of semiconductors, yet disentangling multiple coupling channels in lead halide perovskites remains challenging. We investiga…
Nearest Neighbour-Based Statistics for 21cm-Galaxy Cross-Correlations in the Epoch of Reionization
Anirban Chakraborty, Kwanit Gangopadhyay, Arka Banerjee +1
21cm radiation from neutral hydrogen serves as a direct probe of the Epoch of Reionization. However, both its detection and physical interpretation are severely hindered by contami…
Gravitational Wave Informed Inference of 21-cm Global Signal Parameters
Avinash Tiwari, Sajad A. Bhat, Tirthankar Roy Choudhury +3
Understanding how and when the first stars and galaxies formed remains one of the central challenges in modern cosmology. These structures emerged during the transition from the Da…
Disproportionate influence of site disorder on the evolution of magnetic phases in anti-Heusler alloy AlMnFe
Soumya Bhowmik, Santanu Pakhira, Ashis Kundu +3
Anti-Heusler alloys, being a new addition to the Heusler alloys family, exhibit atomic disorders, and almost all of them are reported as a re-entrant spin-glass system. Although su…
A refined model of secondary photon emission from heavy WIMP annihilations in the Galactic Centre
Rajat Shinde, Julia Djuvsland, Davide Dapaoli +1
Heavy Weakly Interacting Massive Particles (WIMPs) remain a prominent yet less constrained dark matter (DM) candidate, with the Galactic Centre (GC) serving as a prime target for i…
Discovery prospects of a singly-charged scalar at TRISTAN
Joseph George, Nobuchika Okada, Dibyashree Sengupta +1
In this article, we study the associated production of a singly-charged () scalar along with a boson in the newly proposed collider (also known as TRISTAN) a…
Sahyadri: A simulation suite for the cosmology dependence of the Cosmic Web
Saee Dhawalikar, Shadab Alam, Aseem Paranjape +1
We present Sahyadri, a suite of cosmological -body simulations designed to enable precision studies of the low-redshift Universe with next-generation spectroscopic surveys. Sahy…
Interplay of phonons, intertwined density waves, and induced spin density wave in trilayer nickelates Pr4-xLaxNi3O10
Sonia Deswal, Dibyata Rout, Nirmalya Jana +3
Lattice degrees of freedom (DoF) play a central role in correlated electron systems, strongly influencing the dynamics of the underlying charge carriers and spin excitations. In ni…
Kerr Black Hole Shadows in Dispersive Plasma: Frequency-Dependent Geodesics and Shadow Distortions
Sai Karan Mukthapuram, Sandeep Kumar Kataria
The black hole shadow, a direct probe of the event horizon's gravitational influence, has been observationally confirmed by the Event Horizon Telescope (EHT). While theoretical mod…
Entropic alignment of topologically modified ring polymers in cylindrical confinement
Sanjay Bhandarkar, Debarshi Mitra, Jürgen Horbach +1
Under high cylindrical confinement, segments of ring polymers can be localized along the long axis of the cylinder by introducing internal loops within the ring polymer. The emerge…
Measuring accretion disc properties in the transitional millisecond pulsar PSR J1023+0038 using XMM-Newton, NuSTAR, NICER and Chandra
Vishal Jadoliya, Mayukh Pahari, Sudip Bhattacharyya +1
Whether the accretion disc in the X-ray high-mode of transitional millisecond pulsars (tMSP) reaches near the neutron star surface by penetrating the magnetosphere is a crucial que…
Conventional superconductivity in single-crystalline BiPt
S. Sharma, M. Pula, Sajilesh K. P. +10
Binary Bi-Pd/Pt systems have attracted a lot of interest because of their topologically non-trivial nature along with superconductivity. We report the structural and superconductin…
Point-contact enhanced superconductivity in trigonal PtBi2: quest for the origin of high-Tc
O. E. Kvitnitskaya, L. Harnagea, G. Shipunov +6
We studied enhanced superconductivity in point contacts (PCs) based on a type-I Weyl semimetal trigonal t-PtBi2 using both normal metal (Ag, Cu, Pt) and ferromagnetic (Fe, Co, Ni)…
The exceptional set in Cassel's theorem on small cyclotomic integers
Jitendra Bajpai, Srijan Das, Kiran S. Kedlaya +4
In a 1965 paper, R. Robinson made five conjectures about the classification of cyclotomic algebraic integers for which the maximum absolute value in any complex embedding (the hous…
