Superconductivity from the Condensation of Topological Defects in a Quantum Spin-Hall Insulator
Yuhai Liu, Zhenjiu Wang, Toshihiro Sato +4
The discovery that spin-orbit coupling can generate a new state of matter in the form of quantum spin-Hall (QSH) insulators has brought topology to the forefront of condensed matte…
Probing trihedral corner entanglement for Dirac fermions
Grigory Bednik, Lauren E. Hayward Sierens, Minyong Guo +2
We investigate the universal information contained in the Renyi entanglement entropies for a free massless Dirac fermion in three spatial dimensions. Using numerical calculations o…
Electronic structure and spin dynamics of ACo2As2 (A=Ba, Sr, Ca)
Huican Mao, Zhiping Yin
The electronic structures, charge and spin dynamics of the cobalt pnictide compounds ACo2As2 (A=Ba, Sr, Ca) in the paramagnetic state are investigated by using density functional t…
Topological bosonic states on ribbons of honeycomb lattice
Yiping Wang, Xingchuan Zhu, Kefei Zou +2
The topological properties of hardcore bosons on ribbons of honeycomb lattice are studied using quantum Monte Carlo simulations. We map out a rich phase diagram with the superfluid…
Revealing the hidden order in BaTi2As2O via nuclear magnetic resonance
D. W. Song, J. Li, D. Zhao +8
In low-dimensional metallic systems, lattice distortion is usually coupled to a density-wave-like electronic instability due to Fermi surface nesting (FSN) and strong electron-phon…
Doping-driven Antiferromagnetic Insulator -- Superconductor Transition: a Quantum Monte Carlo Study
Tianxing Ma, Da Wang, Congjun Wu
How superconductivity emerges in the vicinity of an antiferromagnetic insulating state is a long-standing issue of strong correlation physics. We study the transition from an antif…
Typicality at quantum-critical points
Lu Liu, Anders W. Sandvik, WenAn Guo
We discuss the concept of typicality of quantum states at quantum-critical points, using projector Monte Carlo simulations of an bilayer Heisenberg antiferromagnet as an il…
Dynamic spin-lattice coupling and nematic fluctuations in NaFeAs
Yu Li, 1 Zahra Yamani, 2 Yu Song +14
We use inelastic neutron scattering to study acoustic phonons and spin excitations in single crystals of NaFeAs, a parent compound of iron pnictide superconductors. NaFeAs exhibits…
Random-Singlet Phase in Disordered Two-Dimensional Quantum Magnets
Lu Liu, Hui Shao, Yu-Cheng Lin +2
We study effects of disorder (randomness) in a 2D square-lattice quantum spin system, the - model with a 6-spin interaction supplementing the Heisenberg exchange…
Anomalous quantum-critical scaling corrections in two-dimensional antiferromagnets
Nvsen Ma, Phillip Weinberg, Hui Shao +3
We study the Néel-paramagnetic quantum phase transition in two-dimensional dimerized Heisenberg antiferromagnets using finite-size scaling of quantum Monte Carlo data. We r…
Pairing symmetry of interacting fermions on twisted bilayer graphene superlattice
Huaiming Guo, Xingchuan Zhu, Shiping Feng +1
The pairing symmetry of an effective Hamiltonian for interacting fermions on a twisted bilayer graphene superlattice is studied with the determinant quantum Monte Carlo method. The…
Engineering Surface Critical Behavior of (2+1)-Dimensional O(3) Quantum Critical Points
Chengxiang Ding, Long Zhang, Wenan Guo
Surface critical behavior (SCB) refers to the singularities of physical quantities on the surface at the bulk phase transition. It is closely related to and even richer than the bu…
