在具有反铁磁海森堡交换的无序自旋系统中，进入和离开磁场感应有序相的转变经过独特的机制。使用量子蒙特卡罗模拟来研究零温度行为，这些中间区域被确定为玻色玻璃相。场致三元组的局域化导致有限的可压缩性，从而导致无序相中的玻璃态。
In disordered spin systems with antiferromagnetic Heisenberg exchange, transitions into and out of a magnetic-field-induced ordered phase pass through unique regimes. Using quantum Monte Carlo simulations to study the zero-temperature behavior, these intermediate regions are determined to be Bose-glass phases. The localization of field-induced triplons causes a finite compressibility and, hence, glassiness in the disordered phase.
