A Geometric Construction of Solutions to 11D Supergravity
Necessary and sufficient conditions are provided for a class of warped product manifolds with non-vanishing flux to be supersymmetric solutions of 11D supergravity. Many non-compact, but complete solutions can be...

On the Construction of Quantum MDS Codes
Quantum maximal-distance-separable (MDS) codes form an important class of quantum codes. The paper is devoted to the construction of new quantum MDS codes based on classical constacyclic codes and cyclic codes...

Open AccessCan we observe fuzzballs or firewalls?
In the fuzzball paradigm the information paradox is resolved because the black hole is replaced by an object with no horizon. One may therefore ask if observations can distinguish a traditional hole from a fuz...

Tunability of spin Hall effect of light with semiconductor metamaterial based on magneto-optical effects
In this paper, we have demonstrated a three-layer structure to explore the characteristics of spin Hall effect of light (SHEL). It is assumed that the structure is made of a semiconductor metamaterial which co...

Entanglement-assisted quantum MDS codes from negacyclic codes
The entanglement-assisted formalism generalizes the standard stabilizer formalism, which can transform arbitrary classical linear codes into entanglement-assisted quantum error-correcting codes (EAQECCs) by us...

New quantum codes constructed from quaternary BCH codes
In this paper, we firstly study construction of new quantum error-correcting codes (QECCs) from three classes of quaternary imprimitive BCH codes. As a result, the improved maximal designed distance of these n...

On entanglement-assisted quantum codes achieving the entanglement-assisted Griesmer bound
The theory of entanglement-assisted quantum error-correcting codes (EAQECCs) is a generalization of the standard stabilizer formalism. Any quaternary (or binary) linear code can be used to construct EAQECCs un...

Open AccessBrane worlds in gravity with auxiliary fields
Recently, Pani et al. explored a new theory of gravity by adding nondynamical fields, i.e., gravity with auxiliary fields (Phys Rev D 88:121502, 2013). In this gravity theory, higher-order derivatives of matter f...

Maximal entanglement entanglement-assisted quantum codes constructed from linear codes
An entanglement-assisted quantum error-correcting code (EAQECC) is a generalization of standard stabilizer quantum code. Maximal entanglement EAQECCs can achieve the EA-hashing bound asymptotically. In this wo...
