TITLEField Induced Spin Supersolidity in Frustrated Spin-1/2 Spin-Dimer Models

ABSTRACTBy means of the recently developed algorithm based on the tensor product states, the magnetization process of frustrated spin-$1/2$ spin-dimer models on a square lattice is investigated. Various field-induced quantum phases are discovered. In particular, clear evidence of a supersolid phase over a finite regime of magnetic field is observed. Critical fields at various field-induced transitions are determined accurately. Our work hence sheds new light on the search of the supersolid phase in real frustrated spin-dimer compounds.
