Anisotropic pyrochlores and the global phase diagram of the checkerboard antiferromagnet
Oleg A. Starykh, Akira Furusaki, Leon Balents
We study the phase diagram of two models of spin-1/2 antiferromagnets composed of corner-sharing tetrahedra, the basis of the pyrochlore structure. Primarily, we focus on the Heise…
Renormalization of impurity scattering in one-dimensional interacting electron systems in magnetic field
T. Hikihara, A. Furusaki, K. A. Matveev
We study the renormalization of a single impurity potential in one-dimensional interacting electron systems in the presence of magnetic field. Using the bosonization technique and…
Kondo Problems in Tomonaga-Luttinger liquids
Akira Furusaki
Quantum impurity problems in Tomonaga-Luttinger liquids (TLLs) are reviewed with emphasis on their analogy to the Kondo problem in Fermi liquids. First, the problem of a static imp…
Boundary contributions to specific heat and susceptibility in the spin-1/2 XXZ chain
A. Furusaki, T. Hikihara
Exact low-temperature asymptotic behavior of boundary contribution to specific heat and susceptibility in the one-dimensional spin-1/2 XXZ model with exchange anisotropy 1/2 < Δ\le…
Ground-state phase diagram of the one-dimensional half-filled extended Hubbard model
M. Tsuchiizu, A. Furusaki
We revisit the ground-state phase diagram of the one-dimensional half-filled extended Hubbard model with on-site (U) and nearest-neighbor (V) repulsive interactions. In the first h…
