Field-induced Tomonaga-Luttinger Liquid phase in a spin ladder

The molecular magnet (C7H10N)2CuBr4, known as DIMPY, is a strong-leg spin ladder with a quantum critical point at Bc~3 T separating a low-field quantum-disordered phase from a...分子磁体(C7H10N)2CuBr4（俗称DIMPY）是一种强腿自旋梯子体系，其在临界磁场Bc≈3 T处存在量子临界点，该临界点将低场量子无序相与……分隔开来。
