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…
