Wigner distributions of quarks for different polarizations
Jai More, Asmita Mukherjee, Sreeraj Nair
We calculate quark Wigner distributions using the light-front wave functions in a dressed quark model. In this model, a proton target is replaced by a simplified spin-1/2 state, na…
An Improved Diffuse Foreground Subtraction by ILC method: CMB Map and Angular Power Spectrum using Planck and WMAP Observations
Vipin Sudevan, Pavan K. Aluri, Sarvesh Kumar Yadav +2
We report an improved technique for diffuse foreground minimization from Cosmic Microwave Background (CMB) maps using a new multi-phase iterative internal-linear-combination (ILC)…
First Order Galilean Superfluid Dynamics
Nabamita Banerjee, Suvankar Dutta, Akash Jain
We study dynamics of (anomalous) Galilean superfluid up to first order in derivative expansion, both in parity-even and parity-odd sectors. We construct a relativistic system -- nu…
Quantum Zeno suppression of dipole-dipole forces
Sebastian Wüster
We consider inter-atomic forces due to resonant dipole-dipole interactions within a dimer of highly excited Rydberg atoms, embedded in an ultra-cold gas. These forces rely on a coh…
A classical optical approach to the `non-local Pancharatnam-like phases' in Hanbury-Brown-Twiss correlations
Arvind, S. Chaturvedi, N. Mukunda
We examine a recent proposal to show the presence of nonlocal Pancharatnam type geometric phases in a quantum mechanical treatment of intensity interferometry measurements upon inc…
Phase Space Distribution of Riemann Zeros
Parikshit Dutta, Suvankar Dutta
We present the partition function of a most generic single plaquette model in terms of representations of unitary group. Extremising the partition function in large N limit…
Non-Hermitian matter wave mixing in Bose Einstein condensates: dissipation induced amplification
S. Wüster, R. El-Ganainy
We investigate the nonlinear scattering dynamics in interacting atomic Bose-Einstein condensates under non-Hermitian dissipative conditions. We show that by carefully engineering a…
Thermal conductance by Dirac fermions in a normal-insulator-superconductor junction of silicene
Ganesh C. Paul, Surajit Sarkar, Arijit Saha
We theoretically study the properties of thermal conductance in a normal-insulator-superconductor junction of silicene for both thin and thick barrier limit. We show that while the…
A New f(R) Model in the Light of Local Gravity Test and Late-time Cosmology
Akhilesh Nautiyal, Sukanta Panda, Avani Patel
We propose a new model of f(R) gravity containing Arctan function in the lagrangian. We show here that this model satisfies fifth force constraint unlike a similar model in Kruglov…
The metastable minima of the Heisenberg spin glass in a random magnetic field
Auditya Sharma, Joonhyun Yeo, M. A. Moore
We have studied zero temperature metastable states in classical -vector component spin glasses in the presence of -component random fields (of strength ) for a variety…
Superconducting Properties of the Non-Centrosymmetric Superconductor Re6Hf
D. Singh, A. D. Hillier, A. Thamizhavel +1
The synthesis and detailed characterization of the noncentrosymmetric superconductor ReHf using powder x-ray diffraction (XRD), magnetization, transport and thermodynamic mea…
Local Scale Invariance and Inflation
Naveen K. Singh, Sukanta Panda
We study the inflation and the cosmological perturbations generated during the inflation in a local scale invariant model. The local scale invariant model introduces a vector field…
A structured description of the genus spectrum of abelian -groups
Jürgen Müller, Siddhartha Sarkar
The genus spectrum of a finite group is the set of all such that acts faithfully on a compact Riemann surface of genus . It is an open problem to find a general desc…
Exciton induced directed motion of unconstrained atoms in an ultracold gas
K. Leonhardt, S. Wüster, J. M. Rost
We demonstrate that through localised Rydberg excitation in a three-dimensional cold atom cloud atomic motion can be rendered directed and nearly confined to a plane, without spati…
Viability of Arctan Model of f(R) Gravity for Late-time Cosmology
Koushik Dutta, Sukanta Panda, Avani Patel
modifications of Einstein's gravity is an interesting possibility to explain the late time acceleration of the Universe. In this work we explore the cosmological viability o…
