Detecting Two Qubit Both-Way Positive Discord States
Kaushiki Mukherjee, Sumana Karmakar, Biswajit Paul +1
Quantum discord plays a pragmatic role in analyzing nonclassical feature of quantum correlations beyond entanglement. It is used in several information processing protocols which l…
Coherence Fraction
Sumana Karmakar, Ajoy Sen, Indrani Chattopadhyay +2
The concept of entanglement fraction is generalized to define coherence fraction of a quantum state. Precisely, it quantifies the proximity of a quantum state to maximally coherent…
Giant negative magnetoresistance and kinetic arrest of first-order ferrimagnetic-antiferomagnetic transition in Ge doped MnSb
Vikram Singh, R Rawat, Pallavi Kushwaha
Effect of Ge substitution on first order ferrimagnetic (FRI) - antiferromagnetic (AFM) transition in MnSb has been studied. It shows that transition temperature (T) can be…
