Synergistic Effect of One- and Two-dimensional Connected Coral-like Li$_{6.25}$Al$_{0.25}$La$_3$Zr$_2$O$_{12}$ in PEO-Based Composite Solid State ElectrolyteSep 07 2019As one of the most promising next-generation energy storage device, lithium metal batteries have been extensively investigated. However, the poor safety issue and undesired lithium dendrites growth hinder the development of lithium metal batteries. The ... More
Quantum correlations with a gap between the sequential and spatial casesJun 30 2017Jul 21 2017We address the problem of whether parties who cannot communicate but share nonsignaling quantum correlations between the outcomes of sharp measurements can distinguish, just from the value of a correlation observable, whether their outcomes were produced ...

Necessary and sufficient condition for contextuality from incompatibilityMay 05 2018Feb 12 2019Measurement incompatibility is the most basic resource that distinguishes quantum from classical physics. Contextuality is the critical resource behind the power of some models of quantum computation and is also a necessary ingredient for many applications ... More
Shell evolution and its indication on the isospin dependence of the spin-orbit splittingAug 31 2012Jun 05 2013The available experimental data on shell evolution indicate that the strength of the spin-orbit (SO) single-particle potential may be enhanced in neutron-rich nuclei. We observe that such a simple scheme destroys the Harmonic Oscillator (HO) magic numbers ... More
Novel Monte Carlo representation for shell model in the complex energy planeJun 05 2013A Monte Carlo method is presented to evaluate quantum states with many particles moving in the continuum. The scattering state is generated at each time by a Monte Carlo random sampling algorithm. The same calculation are repeated until the average energies ... More
Deriving Einstein-Podolsky-Rosen steering inequalities from the few-body Abner Shimony inequalitiesAug 14 2018For the Abner Shimony (AS) inequalities, the simplest unified forms of directions attaining the maximum quantum violation are investigated. Based on these directions, a family of Einstein-Podolsky-Rosen (EPR) steering inequalities is derived from the ... More
