Cusp Singularities in the Magnetization Curve of Frustrated Kondo Necklace Model

Abstract

Magnetization processes of frustrated Kondo necklace model are studied by means of a density matrix renormalization group (DMRG) method and an elementary band theory based on a bond-operator formalism. The DMRG calculations clearly show the cusp singularity in a low-magnetization region ($0

Cusp Singularity in the Magnetization Curve of 1D Quantum Spin Systems

Kouichi Okunishi

We give a short review of the cusp singularity in the magnetization curve of 1D quantum spin systems. We show that the cusp singularity appears for a certain class of nonintegrable frustrated spin systems, using the density matrix renormaziation group method. We also discuss the cusp appearance mechanism on the basis of the one particle dispersion curve of the elementary excitation, where the shape change of the dispersion curve induced by the frustrated interaction plays an essential role.

Middle-field cusp singularities in the magnetization process of one-dimensional quantum antiferromagnets

Kouichi Okunishi, Yasuhiro Hieida, Yasuhiro Akutsu

We study the zero-temperature magnetization process $(M\ensuremath{-}H$ curve) of one-dimensional quantum antiferromagnets using a variant of the density-matrix renormalization group method. For both the $S=1/2$ zig-zag spin ladder and the $S=1$ bilinear-biquadratic chain, we find clear cusp-type singularities in the middle-field region of the $M\ensuremath{-}H$ curve. These singularities are successfully explained in terms of the double-minimum shape of the energy dispersion of the low-lying excitations. For the $S=1/2$ zig-zag spin ladder, we find that the cusp formation accompanies the Fermi-liquid to non-Fermi-liquid transition.

Magnetization of CuGeO3

Suyan Li

As the first inorganic spin-Peierls compound, CuGe03 can be described with an AF Heisenberg model. The magnetization process of CuGe03 is studied using the numerical Density Matrix Renormalization Group (DMRG) technique. The M - H curve of CuGe03 and other one dimensional Heisenberg systems are described, and their different nature are analyzed. In particular, the middle field cusp singularity appears in the M- H curve of CuGe03 is described.

Gap formation and phase transition of the anisotropic Kondo necklace model: Density matrix renormalization group analysis

Juan José Mendoza-Arenas, R. Franco, Jereson Silva-Valencia

We analyze the one-dimensional Kondo necklace model, at zero temperature, with an anisotropy parameter $\ensuremath{\eta}$ in the interaction of the conduction chain, by means of the density matrix renormalization group. We calculate the energy gap and estimate the quantum critical points that separate a Kondo singlet state from an antiferromagnetic state, assuming a Kosterlitz-Thouless tendency. We also observe the correlation functions and the structure factors that support our critical points. The resulting phase diagram is presented and compared to that reported previously using Lanczos calculations. It is shown that the quantum critical points vary very slowly with $\ensuremath{\eta}$, but when $\ensuremath{\eta}$ approaches zero, they drop abruptly.

Magnetic Phase Diagram of theS=1/2 Antiferromagnetic Zigzag Spin Chain in the Strongly Frustrated Region: Cusp and Plateau

Kouichi Okunishi, Takashi Tonegawa

We determine the magnetic phase diagram of the antiferromagnetic(AF) zigzag spin chain in the strongly frustrated region, using the density matrix renormalization group method. We find the magnetization plateau at 1/3 of the full moment accompanying the spontaneous symmetry breaking of the translation, the cusp singularities above and/or below the plateau, and the even-odd effect in the magnetization curve. We also discuss the formation mechanisms of the plateau and cusps briefly.

Phase diagram and critical properties of the frustrated Kondo necklace model in a magnetic field

Takahiro Yamamoto, Kôichirô Ide, Chikara Ishii

The critical properties of the frustrated Kondo necklace model with a half saturation magnetization $(m=1/2)$ have been studied by means of an exact-diagonalization method. It is shown from bosonization technique that the model can be effectively expressed as a quantum sine-Gordon model. Thus it may show three (dimer plateau, N\'eel plateau and Tomonaga-Luttinger liquid) phases due to competitions among the Ising anisotropy $\ensuremath{\Delta},$ and the nearest- and next-nearest-neighbor exchange interactions ${J}_{1}$ and ${J}_{2}.$ The boundary lines on the $\ensuremath{\Delta}$-${J}_{2}{/J}_{1}$ phase diagram separating the three phases are determined by the method of level spectroscopy, based on the conformal field theory.
