Conditional global entanglement in a Kosterlitz-Thouless quantum phase transition
Elahe Samimi, Mohammad Hossein Zarei, Afshin Montakhab
Entanglement is known as an important indicator for characterizing different types of quantum phase transitions (QPTs), however it faces some challenges in the Kosterlitz-Thouless…

On the robustness of topological quantum codes: Ising perturbation
Mohammad Hossein Zarei
We study the phase transition from two different topological phases to the ferromagnetic phase by focusing on points of the phase transition. To this end, we present a detailed map…
