Response of entanglement to annealed vis-à-vis quenched disorder in quantum spin models
Anindita Bera, Debasis Sadhukhan, Debraj Rakshit +2
We investigate bipartite entanglement in random quantum models at equilibrium. Depending on the intrinsic time scales associated with equilibration of the random parameters an…
Phase boundaries in alternating field quantum XY model with Dzyaloshinskii-Moriya interaction: Sustainable entanglement in dynamics
Saptarshi Roy, Titas Chanda, Tamoghna Das +3
We report all phases and corresponding critical lines of the quantum anisotropic transverse XY model with Dzyaloshinskii-Moriya (DM) interaction along with uniform and alternating…
Emergence of entanglement with temperature and time in factorization-surface states
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
There exist zero-temperature states in quantum many-body systems that are fully factorized, thereby possessing vanishing entanglement, and hence being of no use as resource in quan…
Quantum discord and its allies: a review
Anindita Bera, Tamoghna Das, Debasis Sadhukhan +3
We review concepts and methods associated with quantum discord and related topics. We also describe their possible connections with other aspects of quantum information and beyond,…
