Entanglement is known as an important indicator for characterizing different types of
quantum phase transitions (QPTs); however, it faces some challenges in the Kosterlitz …

Finding suitable indicators for characterizing quantum phase transitions plays an important
role in understanding different phases of matter. It is especially important for fracton phases …

We examine the condensation and confinement mechanisms exhibited by a deformed toric
code model proposed in [Castelnovo and Chamon, Phys. Rev. B 77, 054433 (2008)]. The …

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 multipartite …

While local unitary transformations are used for identifying quantum states that are in the
same topological class, nonlocal unitary transformations are also important for studying the …

Enhancing robustness of topological orders against perturbations is one of the main goals in
topological quantum computing. Since the kinetic of excitations is in conflict with the …

In frustrated spin ladders, the interplay of frustration and correlations leads to the familiar
Haldane (H) and rung-singlet (RS) phases. The nature of the transition between these two …
