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…
