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…
Quantum FFLO state in clean layered superconductors
Kok Wee Song, Alexei E. Koshelev
We investigate the influence of Landau quantization on the superconducting instability for a pure layered superconductor in the magnetic field directed perpendicular to the layers.…
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-…
Lecture Notes of Tensor Network Contractions
Shi-Ju Ran, Emanuele Tirrito, Cheng Peng +4
Tensor network (TN), a young mathematical tool of high vitality and great potential, has been undergoing extremely rapid developments in the last two decades, gaining tremendous su…
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…
