Scientists make first detection of exotic “X” particles in quark-gluon plasma（图）
夸克 胶子 等离子体 “X”粒子
2023/6/9
In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons — elementary particles that briefly glommed together in countless combin...

Spin entanglement of two spin-1/2 particles in a classical gravitational field
Spin entanglement spin-1/2 particles classical gravitational field
2010/11/8
The effect of a classical gravitational field on the spin entanglement of a system of two spin-1/2 particles moving in the curved spacetime is discussed. The system is described by a two-particle Gaus...

Squeezing Inequalities Entanglement Identical Particles
2010/10/18
By identifying non-local effects in systems of identical Bosonic qubits through correlations of their commuting observables, we show that entanglement is not necessary to violate certain squeezing ine...
