Effect of perturbations on the kagome S=12 antiferromagnet at all temperatures

The ground state of the $S=1/2$ kagome Heisenberg antiferromagnet is now recognized as a spin liquid, but its precise nature remains unsettled, even if more and more clues point towards a gapless

Spin liquid mediated RKKY interaction

This work investigates the possible ordering of nuclear spins that interact through an underlying lattice of the two-dimensional spin-1/2 kagome antiferromagnet (KHAF), and demonstrates that the interaction is predominately shaped by the lattice symmetries of the underlying spin liquid.

Method to observe the anomaly of magnetic susceptibility in quantum spin systems

We propose a new method for studying the anomaly of magnetic susceptibility $\chi$ that indicates a phase transition for quantum spin systems. In addition, we introduce the fourth derivative $A$ of

Critical magnetization behavior of the triangular- and kagome-lattice quantum antiferromagnets

We investigate $S=1/2$ quantum spin antiferromagnets on the triangular and Kagome lattices in a magnetic field, using the numerical exact diagonalization. We focus particularly on an anomalous

Spin-Liquid Ground State of the S = 1/2 Kagome Heisenberg Antiferromagnet

This work uses the density matrix renormalization group to perform accurate calculations of the ground state of the nearest-neighbor quantum spin S = 1/2 Heisenberg antiferromagnet on the kagome lattice and provides strong evidence that, for the infinite two-dimensional system, the groundState of this model is a fully gapped spin liquid.

Density matrix renormalization group numerical study of the kagome antiferromagnet.

The spin-1/2 antiferromagnetic Heisenberg model on the kagome lattice is numerically studied using the density-matrix renormalization group method and is found to be a magnetically disordered spin liquid, characterized by an exponential decay of spin-spin correlation function in real space and a magnetic structure factor showing system-size independent peaks at commensurate magnetic wave vectors.
