摘要翻译：
用重整化群论研究了自旋1/2量子海森堡模型。在d\Geq3维上得到了温度和反铁磁键几率p的强不对称相图。在接近纯铁磁和反铁磁体系的高温下，不对称性随着d的增加而消失。然而，在有限温度下，非对称性在所有维度上都保持不变，反铁磁相退到铁磁相。在d\Geq6中，铁磁相和反铁磁相之间直接出现了一个有限温度的二级相边界，在其与顺磁相边界的相交处产生了一个新的多晶点。当d=3,4,5时，一个达到零温度的顺磁相不对称地介入铁磁相和重入反铁磁相之间。在任何维度上都不存在自旋玻璃相。

英文摘要：
The spin-1/2 quantum Heisenberg model is studied in all spatial dimensions d by renormalization-group theory. Strongly asymmetric phase diagrams in temperature and antiferromagnetic bond probability p are obtained in dimensions d \geq 3. The asymmetry at high temperatures approaching the pure ferromagnetic and antiferromagnetic systems disappears as d is increased. However, the asymmetry at low but finite temperatures remains in all dimensions, with the antiferromagnetic phase receding to the ferromagnetic phase. A finite-temperature second-order phase boundary directly between the ferromagnetic and antiferromagnetic phases occurs in d \geq 6, resulting in a new multicritical point at its meeting with the boundaries to the paramagnetic phase. In d=3,4,5, a paramagnetic phase reaching zero temperature intervenes asymmetrically between the ferromagnetic and reentrant antiferromagnetic phases. There is no spin-glass phase in any dimension.
