This quantum critical phenomenon is associated with entanglement between the atomic ensemble and the field. 而且这种量子临界(QC)现象与集体原子和场之间的纠缠有关系。
And also calculates the ground-state entanglement under various control parameters and gives expressions for the quantum critical points at which quantum phase transition takes place. 文章还计算了参数取不同值情况下的基态纠缠并给出了发生量子相变的临界点的表达式。
A zero-temperature quantum critical point holds the key to understanding a wide range of behavior in many condensed matter systems. Examples include rare-earth magnetic insulators, high-temperature superconductors and two-dimensional electron gases. 通过零温量子临界(QC)点的研究,可获知物质系统更广泛范围的行为,包括稀土磁性绝缘体,高温超导体和二维电子气体等。
Further comparison of doping and temperature dependent date, we obtain the electron behaviors near the quantum critical point and the quantum ground state. 通过比较、分析材料在量子临界(QC)点及其附近的电子行为,我们得出量子基态的性质。
Recently, it was discovered that, near the quantum critical point the QPT system possesses the ultra-sensitivity in its dynamical evolution. 最近,人们发现对于一个量子相变系统,在它的临界点附近,量子相变系统的动力学具有极高的敏感性。
