Supersolid phase of Three-dimensional spin and hardcore-boson models
H. T. Ueda, K. Totsuka
We study the stability of solid- and supersolid (SS) phases of a three-dimensional spin- and a hardcore-Bose-Hubbard models on a body-centered cubic lattice. To see the quantum eff…

Dilute-Bose-Gas Approach to ground state phases of 3D quantum helimagnets under high magnetic field
H. T. Ueda, K. Totsuka, T. Momoi
We study high-field phase diagram and low-energy excitations of three-dimensional quantum helimagnets. Slightly below the saturation field, the emergence of magnetic order may be m…

Magnon BEC and various phases of 3D quantum helimagnets under high magnetic field
H. T. Ueda, K. Totsuka
We study high-field phase diagram and low-energy excitations of three-dimensional quantum helimagnets. Slightly below the saturation field, the emergence of magnetic order may be v…
