New Formalism for Modelling Flowing Plasmas in a Magnetic Field
Subhasish Bag, Ashish Ganguli, Vikrant Saxena +2
A new formalism for modelling a flowing plasma in a magnetic field, having potential for application in plasma thrusters, materials processing, space plasmas, etc., is developed. I…
Experimental and Theoretical Study of Flow Dynamics of Expanding Hydrogen Plasma from an ECR Plasma Source
Priti Singh, Ramesh Narayanan, Ashish Ganguli +2
The flow of moderately dense (n {\approx} 10^{11} cm^{-3}) hydrogen plasma with high electron temperature (T_{e} {\approx} 30 - 35 eV) and plasma potential (V_{p} {\approx} 100 V),…
A maximum concurrence criterion to investigate absolutely maximally entangled states
Subhasish Bag, Ramita Sarkar, Prasanta K. Panigrahi
We propose a straightforward method to determine the maximal entanglement of pure states using the criterion of maximal I-concurrence, a measure of entanglement. The square of conc…
Nonlinear evolution of a cold non-relativistic electron-ion plasma with an arbitrary initial density profile: A phase mixing perspective
Subhasish Bag, Vikrant Saxena
Using a perturbative approach, an evolution equation for the space charge density, correct up to the third order, is deduced for arbitrary initial density profiles of the electron…
Fluid Simulation for a Finite Size Plasma
Subhasish Bag, Vikrant Saxena, Amita Das
Studies on finite-size plasma have attracted a lot of attention lately. They can form by ionizing liquid droplets by lasers. The dynamical behavior of such plasma droplets is, ther…
Achieving Heisenberg limit in the phase measurement through three-qubit graph states
Subhasish Bag, Ramita Sarkar, Prasanta K. Panigrahi
We study the reciprocal of the mean quantum Fisher information (RMQFI), for general three qubit states, having graph and hypergraph states as special cases, for identifying g…
