Quantum phase transition in a dimerized chain with hexamer distortion
Mahboobeh Shahri Naseri, George I. Japaridze, Saeed Mahdavifar +1
We consider the dimerized spin-1/2 Heisenberg chain with spin hexameric distortion of the exchange pattern and study the zero-temperature phase diagram in the parameter space $(J_{…

From fidelity to entanglement of entropy of the one-dimensional transverse-field quantum compass model
Mostafa Motamedifar, Somayyeh Nemati, Saeed Mahdavifar +1
We study fidelity and fidelity susceptibility by addition of entanglement of entropy in the one-dimensional quantum compass model in a transverse magnetic field numerically. The wh…
