Abstract: We construct solutions of higher-dimensional Einstein gravity coupled to nonlinear $$\sigma $$σ-model with cosmological constant. The $$\sigma $$σ-model can be perceived as exterior configuration of a spontaneously-broken $$SO(D-1)$$SO(D-1) global higher-codimensional “monopole”. Here we allow the… read more here.

Abstract: Entanglement plays a vital and in many cases non-replaceable role in the quantum network communication. Here, we propose two new protocols to jointly and remotely prepare a special so-called bipartite equatorial state which is hybrid… read more here.

Abstract: A ($3+1$)-dimensional Einstein-Gauss-Bonnet theory of gravity has been recently formulated by Glavan and Lin [D. Glavan and C. Lin, Phys. Rev. Lett. 124, 081301 (2020)] which is different from the pure Einstein theory, i.e., bypasses… read more here.

Abstract: Steering nonlocality is the fundamental property of quantum mechanics, which has been widely demonstrated in some systems with qubits. Recently, theoretical works have shown that the high-dimensional (HD) steering effect exhibits novel and important features,… read more here.

DOI: 10.1142/s021773231750064x
Abstract: We present an infinite class of one-parameter scalar field extensions to the Banados, Teitelboim and Zanelli (BTZ) black hole in 2 + 1 dimensions. By virtue of the scalar charge, the thin-shell wormhole supported by… read more here.
