String orders in the Luttinger liquid phase of one-dimensional spin-1/2 systems
Hadi Cheraghi, Majid Jafar Tafreshi, Saeed Mahdavifar
Luttinger liquid (LL) phase refers to a quantum phase which emerges in the ground state phase diagram of quite often low-dimensional quantum magnets as spin-1/2 XX, XYY and frustra…
Ineffectiveness of the Dzyaloshinskii-Moriya interaction in the dynamical quantum phase transition in the ITF model
H. Cheraghi, S. Mahdavifar
Quantum phase transition occurs at a quantum critical value of a control parameter such as the magnetic field in the Ising model in a transverse magnetic field (ITF). Recently, it…
Dynamical quantum correlations after sudden quenches
Utkarsh Mishra, Hadi Cheraghi, Saeed Mahdavifar +2
We employ the mean-field approach in the fermionic picture of the spin-1/2 XXZ chain to investigate the dynamics of bipartite quantum discord and concurrence under sudden quenching…
