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…
Global entanglement in a topological quantum phase transition
Elahe Samimi, Mohammad Hossein Zarei, Afshin Montakhab
A useful approach to characterize and identify quantum phase transitions lies in the concept of multipartite entanglement. In this paper, we consider well-known measures of multipa…
Classical criticality establishes quantum topological order
Mohammad Hossein Zarei, Afshin Montakhab
We establish an important duality correspondence between topological order in quantum many body systems and criticality in ferromagnetic classical spin systems. We show how such a…
Phase transition in a noisy Kitaev toric code model
Mohammad Hossein Zarei, Afshin Montakhab
It is well-known that the partition function of a classical spin model can be mapped to a quantum entangled state where some properties on one side can be used to find new properti…
Dual correspondence between classical spin models and quantum CSS states
Mohammad Hossein Zarei, Afshin Montakhab
The correspondence between classical spin models and quantum states has attracted much attention in recent years. However, it remains an open problem as to which specific spin mode…
Multi-partite entanglement and quantum phase transition in the one-, two-, and three-dimensional transverse field Ising model
Afshin Montakhab, Ali Asadian
In this paper we consider the quantum phase transition in the Ising model in the presence of a transverse field in one, two and three dimensions from a multi-partite entanglement p…
