Real Space Renormalization Group for One-Dimensional Ising Chains
Shraddha singh, Vijay Singh
We apply the real space Renormalisation Group (RNG) technique to a variety of one-dimensional Ising chains. We begin by recapitulating the work of Nauenberg for an ordered Ising ch…
LRS Bianchi I model with bulk viscosity in f(R,T) gravity
S. Jokweni, Vijay Singh, Aroonkumar Beesham
Locally-rotationally-symmetric Bianchi type-I viscous and non -viscous cosmological models are explored in general relativity (GR) and in f(R,T) gravity. Solutions are obtained by…
Plane symmetric model in gravity
Vijay Singh, Aroonkumar Beesham
A plane symmetric Bianchi-I model is explored in gravity, where is the Ricci scalar and is the trace of energy-momentum tensor. The solutions are obtained with the…
LRS Bianchi I model with constant expansion rate in gravity
Vijay Singh, Aroonkumar Beesham
An LRS Bianchi-I space-time model is studied with constant Hubble parameter in gravity. Although a single (primary) matter source is considered, an additional matter…
Plane symmetric model with constant deceleration parameter
Vijay Singh, Aroonkumar Beesham
A plane symmetric Bianchi I model is considered with constant deceleration parameter, , where . The model with violates the NEC throughout the evolution, and h…
LRS Bianchi I model with constant deceleration parameter
Vijay Singh, Aroonkumar Beesham
An LRS Bianchi I model is considered with constant deceleration parameter, , where is a constant. The physical and kinematical behaviour of the models for and…
LRS Bianchi I model with perfect fluid equation of state
Vijay Singh, Aroonkumar Beesham
The general solution of the field equations in LRS Bianchi-I space-time with perfect fluid equation-of-state (EoS) is presented. The models filled with dust, vacuum energy, Zel'dov…
Magnetic Order and Lattice Instabilities in NiMnSn Heusler based Magnetic Shape-Memory Alloys
Vijay Singh, Ambroise van Roekeghem, S. K. Panda +3
The magnetic correlations in the austenite phase and the consequent martensitic transition in inverse magnetocaloric alloys, NiMnSn, have been a matter of deb…
A Moving-Trap Zeeman Decelerator
Lewis A. McArd, Arin Mizouri, Paul A. Walker +4
We present a moving-trap Zeeman decelerator (MTZD) for use in molecular beam manipulation and magnetic-trapping experiments of paramagnetic atoms and molecules. The 0.49 m MTZD con…
Friedmann cosmology with particle creation in modified gravity
C. P. Singh, Vijay Singh
The theoretical and observational consequences of thermodynamics of open systems, which allow particle creation are investigated in modified ( is the Ricci scalar and $…
From explosive to infinite-order transitions on a hyperbolic network
Vijay Singh, C. T. Brunson, Stefan Boettcher
We analyze the phase transitions that emerge from the recursive design of certain hyperbolic networks that includes, for instance, a discontinuous ("explosive") transition in ordin…
Scaling of Clusters near Discontinuous Percolation Transitions in Hyperbolic Networks
Vijay Singh, Stefan Boettcher
We investigate the onset of the discontinuous percolation transition in small-world hyperbolic networks by studying the systems-size scaling of the typical largest cluster approach…
String Cosmology with Magnetic field in Anisotropic Space-time
C. P. Singh, Vijay Singh
In this paper we study the effect of the magnetic field in string cosmology for a spatially homogenous and anisotropic Bianchi type -V space-time model. In order to study the effec…
Ordinary Percolation with Discontinuous Transitions
S. Boettcher, V. Singh, R. M. Ziff
Percolation on a one-dimensional lattice and fractals such as the Sierpinski gasket is typically considered to be trivial because they percolate only at full bond density. By dress…
