Dynamical phase transition in neutron stars
R Prasad, Ritam Mallick
In this work, we have studied the dynamical evolution of the shock front in a neutron star. The shock wave is expected to possess enough strength to ignite the nuclear matter there…
A Global ILC Approach in Pixel Space over Large Angular Scales of the Sky using CMB Covariance Matrix

We propose a new internal linear combination (ILC) method in the pixel space, applicable on large angular scales of the sky, to estimate a foreground minimized Cosmic Microwave Bac…
Property (T), property (F) and residual finiteness for discrete quantum groups
Angshuman Bhattacharya, Michael Brannan, Alexandru Chirvasitu +1
We investigate connections between various rigidity and softness properties for discrete quantum groups. After introducing a notion of residual finiteness, we show that it implies…
Phase diagram for the Harper model of the honeycomb lattice
Geo Jose, Rajesh Malla, Varadharajan Srinivasan +2
The Harper equation arising out of a tight-binding model of electrons on a honeycomb lattice subject to a uniform magnetic field perpendicular to the plane is studied. Contrasting…
Entanglement contour perspective for strong area law violation in a disordered long-range hopping model
Nilanjan Roy, Auditya Sharma
We numerically investigate the link between the delocalization-localization transition and entanglement in a disordered long-range hopping model of spinless fermions by studying va…
Time-reversal symmetry breaking in noncentrosymmetric superconductor Re6Hf:further evidence for unconventional behaviour in the alpha-Mn family of materials
D. Singh, J. A. T. Barker, A. Thamizhavel +3
The discovery of new families of unconventional superconductors is important both experimentally and theoretically, especially if it challenges current models and thinking. By usin…
Entanglement and Complete Positivity: Relevance and Manifestations in Classical Scalar Wave Optics
Arvind, S. Chaturvedi, N. Mukunda
Entanglement of states and Complete Positivity of maps are concepts that have achieved physical importance with the recent growth of quantum information science. They are however m…
On a generalized Brauer group in mixed characteristic cases
Makoto Sakagaito
We define a generalization of the Brauer group for an equi-dimensional scheme and . In the case where is the spectrum of a local r…
Superconducting properties of the noncentrosymmetric superconductor TaOs
D. Singh, Sajilesh K. P., S. Marik +2
The noncentrosymmetric superconductor TaOs has been characterized using x-ray diffraction, resistivity, magnetization, and specific heat measurements. Magnetization and specific he…
Superconducting and normal-state properties of the noncentrosymmetric superconductor Re6Zr
D. A. Mayoh, J. A. T. Barker, R. P. Singh +3
We systematically investigate the normal and superconducting properties of non-centrosymmetric ReZr using magnetization, heat capacity, and electrical resistivity measurement…
Wigner Distributions For Gluons
Jai More, Asmita Mukherjee, Sreeraj Nair
We investigate the gluon Wigner distributions for unpolarized, longitudinally polarized and transversely polarized target state. Instead of a nucleon, we take the target state to b…
Enhancement of Two photon absorption with Ni doping in the dilute magnetic Semiconductor ZnO Crystalline Nanorods
Amit Kumar Rana, Aneesh. J, Yogendra Kumar +4
In this letter, we have investigated the third-order optical nonlinearities of high-quality Ni doped ZnO nanorods crystallized in wurtzite lattice, prepared by the wet chemical met…
A finite temperature study of ideal quantum gases in the presence of one dimensional quasi-periodic potential

We show that large phases of a dimensional generic unitary matrix model (UMM) can be described in terms of topologies of two dimensional droplets on a plane spanned by eige…
Rydberg Aggregates
S. Wüster, J. -M. Rost
We review Rydberg aggregates, assemblies of a few Rydberg atoms exhibiting energy transport through collective eigenstates, considering isolated atoms or assemblies embedded within…
Effect of magnetic field on the burning of a neutron star
Ritam Mallick, Amit Singh
In this article, we present the effect of a strong magnetic field in the burning of a neutron star (NS). We have used relativistic magneto-hydrostatic (MHS) conservation equations…
Jet Identification with Zest
Ankita Budhraja, Ambar Jain
We present a new observable zest and demonstrate its potential to differentiate between jets originated by gluons, top quark and vector bosons. Zest has salient properties such as…
