Magnetic phase diagram of a spin-1/2 XXZ chain with modulated Dzyaloshinskii-Moriya interaction
G. I. Japaridze, H. Cheraghi, S. Mahdavifar
We consider the ground-state phase diagram of a one-dimensional spin-1/2 XXZ chain with spatially modulated Dzyaloshinskii-Moriya interaction in the presence of applied along with…
Dynamics of coherence: Maximal quantum Fisher information vs. Loschmidt echo
Hadi Cheraghi, Saeed Mahdavifar
We consider the dynamics of maximal quantum Fisher information (MQFI) after sudden quenches for the one-dimensional transverse-field Ising model. Our results show, the same as Losc…
Probing the Possibilities of Ergodicity in the 1D Spin-1/2 XY Chain with Quench Dynamics
H. Cheraghi, S. Mahdavifar
Ergodicity sits at the heart of the connection between statistical mechanics and dynamics of a physical system. By fixing the initial state of the system into the ground state of t…
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…
