Quantum Discord and Logarithmic Negativity in the Generalized n-qubit Werner State
M. S. Ramkarthik, Devvrat Tiwari, Pranay Barkataki
Quantum Discord (QD) is a measure of the total quantum non-local correlations of a quantum system. The formalism of quantum discord has been applied to various two-qubit mixed stat…

Entanglement signatures for the dimerization transition in the Majumdar-Ghosh model
M. S. Ramkarthik, V. Ravi Chandra, Arul Lakshminarayan
The transition from a gapless liquid to a gapped dimerized ground state that occurs in the frustrated antiferromagnetic Majumdar-Ghosh (or Heisenberg) model is revisited…
