Topological order is important in many aspects of condensed matter physics and has been
extended to bosonic systems. In this Letter we report on the nontrivial topology of the …

We apply the quantum renormalization group (QRG) method to study the relationship
between entanglement and quantum phase transition in the spin-1/2 XY chain. The tripartite …

An exactly solvable Kitaev model in a two-dimensional square lattice exhibits a topological
quantum phase transition which is different from the symmetry-breaking transition at zero …

We study the properties of multipartite quantum correlation (MQC) in a one-dimensional spin-
1/2 XY chain, where the three-spin reduced states are focused on and the four introduced …

We study the emission of a single-photon by a two-level emitter inside an atomic cavity
consisting of two atomic mirrors coupled to a one-dimensional waveguide. With proper …

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

Quantum phase transition and entanglement in the Rabi model with a squeezed light are
investigated. We find a special unitary-transformation method that removes the …

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 …

We use two-site quantum nonlocality to identify the topological quantum phase transitions
(TQPTs) of the extended Ising model driven by varying system parameters. We investigate …
