Reentrance of Topological Phase in Spin-1 Frustrated Heisenberg Chain
Yuan Yang, Shi-Ju Ran, Xi Chen +4
For the Haldane phase, the magnetic field usually tends to break the symmetry and drives the system into a topologically trivial phase. Here, we report a novel reentrance of the Ha…
Thermodynamics of Spin-1/2 Kagomé Heisenberg Antiferromagnet: Algebraic Paramagnetic Liquid and Finite-Temperature Phase Diagram
Xi Chen, Shi-Ju Ran, Tao Liu +3
Quantum fluctuations from frustration can trigger quantum spin liquids (QSLs) at zero temperature. However, it is unclear how thermal fluctuations affect a QSL. We employ state-of-…
Fermionic algebraic quantum spin liquid in an octa-kagome frustrated antiferromagnet
Cheng Peng, Shi-Ju Ran, Tao Liu +2
We investigate the ground state and finite-temperature properties of the spin-1/2 Heisenberg antiferromagnet on an infinite octa-kagome lattice by utilizing state-of-the-art tensor…
Quantum phase transition, universality and scaling behaviors in the spin-1/2 Heisenberg model with ferromagnetic and antiferromagnetic competing interactions on honeycomb lattice
Yi-Zhen Huang, Bin Xi, Xi Chen +3
The quantum phase transition, scaling behaviors, and thermodynamics in the spin-1/2 quantum Heisenberg model with antiferromagnetic coupling in armchair direction and ferroma…
