Abstract

We study the ground state phase diagram of the twisted three-leg spin tube in magnetic fields by the density matrix renormalization group (DMRG) method. The twisted spin tube is composed of triangular unit cells and possesses strong quantum fluctuations under geometrical frustration. We apply the sine square deformation method to remove strong boundary effects and obtain smooth magnetization curves without steps of finite systems. With the analysis of the magnetization curves and correlation functions we determine the ground state phase diagram consisting of (a) a Tomonaga-Luttinger (TL) liquid characterized by spin-3=2 Heisenberg model, (b) three-sublattice state named UUD with 1=3 magnetization and (c) TL-liquid of massless chirality with 1=3 magnetization plateau, (d) TL-liquid of massless spin mode with or without chirality quasi long-range order.
