Estimating phase transition of perturbed J1-J2 Heisenberg quantum chain in mixtures of ground and first excited states
Sayan Mondal, George Biswas, Ahana Ghoshal +2
We show that the nearest neighbour entanglement in a mixture of ground and first excited states - a subjacent state - of the J1-J2 Heisenberg quantum spin chain can be used as an o…
Spread and asymmetry of typical quantum coherence and their inhibition in response to glassy disorder
George Biswas, Santanu Sarkar, Anindya Biswas +1
We consider the average quantum coherences of typical redits and qudits - vectors of real and complex Hilbert spaces - with the analytical forms stemming from the symmetry of Haar-…
Shared purity and concurrence of a mixture of ground and low-lying excited states as indicators of quantum phase transitions
George Biswas, Anindya Biswas, Ujjwal Sen
We investigate the efficacy of shared purity, a measure of quantum correlation that is independent of the separability-entanglement paradigm, as a quantum phase transition indicato…
