Competing states in the triangular-lattice - Heisenberg model: a dynamical density-matrix renormalization group study
Shengtao Jiang, Steven R. White, Steven A. Kivelson +1
Previous studies of the triangular-lattice -- Heisenberg antiferromagnet have inferred the existence of a non-magnetic ground-state phase for an intermediate rang…
Quantifying the Phase Diagram and Hamiltonian of Kagome Antiferromagnets: Bridging Theory and Experiment
Shengtao Jiang, Arthur C. Campello, Wei He +4
Spin- kagome antiferromagnets are leading candidates for realizing quantum spin liquid (QSL) ground states. While QSL ground states are predicted for the pure Heisenberg model…
The Saga of -RuCl: Parameters, Models, and Phase Diagrams
Marius Möller, P. A. Maksimov, Shengtao Jiang +3
RuCl was likely the first ever deliberately synthesized ruthenium compound, following the discovery of the Ru element in 1844. For a long time it was known as an oxidati…
BaCo(AsO): Strong Kitaev, After All
Pavel A. Maksimov, Shengtao Jiang, L. P. Regnault +1
The inelastic neutron scattering results and their analysis unequivocally point to a dominant Kitaev interaction in the honeycomb-lattice cobaltate BaCo(AsO). Our aniso…
Ground-State-Based Model Reduction with Unitary Circuits
Shengtao Jiang, Steven R. White
We present a method to numerically obtain low-energy effective models based on a unitary transformation of the ground state. The algorithm finds a unitary circuit that transforms t…
Phase Diagram of the Easy-Axis Triangular-Lattice Model
Cesar A. Gallegos, Shengtao Jiang, Steven R. White +1
The phase diagram of the easy-axis triangular-lattice model is investigated using the density-matrix renormalization group and analytical insights. We fin…
