Tetrapartite entanglement features of W-Class state in uniform acceleration
Qian Dong, Ariadna J. Torres-Arenas, Guo-Hua Sun +1
Using the single-mode approximation, we first calculate entanglement measures such as negativity ( and tangles) and von Neumann entropy for a tetrapartite W-Class system…

Tetrapartite entanglement measures of W-Class in noninertial frames
Ariadna J. Torres-Arenas, Edgar O. Lopez-Zuniga, J. Antonio Saldana-Herrera +3
We present the entanglement measures of a tetrapartite W-Class entangled system in noninertial frame, where the transformation between Minkowski and Rindler coordinates is applied.…

Semi-exact solutions of the Razavy potential
Qian Dong, F. A. Serrano, Guo-Hua Sun +2
In this work we study the quantum system with the symmetric Razavy potential and show how to find its exact solutions. We find that the solutions are given by the confluent Heun fu…
