Phase diagram of the Hubbard model on a honeycomb lattice: A cluster slave-spin study
Ming-Huan Zeng, Y. -J. Wang, Tianxing Ma
The cluster slave-spin method is implemented to research the ground state properties of the honeycomb lattice Hubbard model with doping and coupling being its parameters. A…
Phase diagram of the Hubbard model on a square lattice: A cluster slave-spin study
Ming-Huan Zeng, Tianxing Ma, Y. -J. Wang
We employ the cluster slave-spin method to investigate systematically the ground state properties of the Hubbard model on a square lattice with doping and coupling strength …
Low energy excitations and dynamic Dzyaloshinskii-Moriya interaction in -NaVO studied by far infrared spectroscopy
T. Rõõm, D. Hüvonen, U. Nagel +2
We have studied far infrared transmission spectra of alpha'-NaV2O5 between 3 and 200cm-1 in polarizations of incident light parallel to a, b, and c crystallographic axes in magneti…
Field-Induced Ising Criticality and Incommensurability in Anisotropic Spin-1 Chains
Y. -J. Wang
Quantum phase transitions induced by an external magnetic field in the Haldane-gapped spin-1 chains are studied in a fermionic field-theoretic description of the model. In the case…
Phase diagrams of the generalized spin-1/2 ladder under staggered field and dimerization: A renormalization group study
Y. -J. Wang
In the weak-coupling regime of the continuous theories, two sets of one-loop renormalization group equations are derived and solved to disclose the phase diagrams of the antiferrom…
