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…
Quantum correlations in periodically driven spin chains: Revivals and steady-state properties
Utkarsh Mishra, R. Prabhu, Debraj Rakshit
We study the dynamics of microscopic quantum correlations, viz., bipartite entanglement and quantum discord between nearest neighbor sites, in Ising spin chain with a periodically…
Adiabatic freezing of entanglement with insertion of defects in a one-dimensional Hubbard model
Sreetama Das, Sudipto Singha Roy, Himadri Shekhar Dhar +3
We report on ground state phases of a doped one-dimensional Hubbard model, which for large onsite interactions is governed by the - Hamiltonian, where the extant entanglement…
On the observability of Pauli crystals
Debraj Rakshit, Jan Mostowski, Tomasz Sowiński +2
The best known manifestation of the Fermi-Dirac statistics is the Pauli exclusion principle: no two identical fermions can occupy the same one-particle state. This principle enforc…
