Local Quantum Criticality in the Two-dimensional Dissipative Quantum XY Model
Lijun Zhu, Yan Chen, Chandra M. Varma
We use quantum Monte-Carlo simulations to calculate the phase diagram and the correlation functions for the quantum phase transitions in the two-dimensional dissipative XY model wi…
Disorder suppressed charge-density-wave and its origin in 1T-TaSe2-xTex
Y. Liu, D. F. Shao, W. J. Lu +9
In the sake of connecting the charge-density-wave (CDW) of TaSe and single-\emph{\textbf{q}} CDW-type distortion of TaTe, we present an overall electronic phase diagram of…
Long-range magnetic interaction and frustration in double perovskite SrNiIrO
Xuedong Ou, Zhengwei Li, Fengren Fan +2
SrNiIrO would be a ferromagnetic (FM) insulator in terms of the common superexchange mechanism between the first nearest neighboring (1NN) magnetic ions Ni ($t_{…
Global phase diagram, possible chiral spin liquid and topological superconductivity in the triangular Kitaev-Heisenberg model
Kai Li, Shun-Li Yu, Jian-Xin Li
The possible ground states of the undoped and doped Kitaev-Heisenberg model on a triangular lattice are studied. For the undoped system, a combination of the numerical exact diagon…
Topologically distinct critical theories emerging from the bulk entanglement spectrum of integer quantum Hall states on a lattice
Qiong Zhu, Xin Wan, Guang-Ming Zhang
The critical theories for the topological phase transitions of integer quantum Hall states to a trivial insulating state with the same symmetry can be obtained by calculating the g…
Collective modes in a Dirac insulator with short range interactions
Xi Luo, Yue Yu, Long Liang
We study a Haldane model with nearest neighbor interactions. We find one-dimensional like collective modes arising due to the interplay of pseudo-spin and valley degrees of freedom…
Distinct Spin Liquids and their Transitions in Spin-1/2 XXZ Kagome Antiferromagnets
Yin-Chen He, Yan Chen
By using the density matrix renormalization group, we study the spin-liquid phases of spin- XXZ kagome antiferromagnets. We find that the emergence of spin liquid phase does n…
Reversing ferroelectric polarization in multiferroic DyMn2O5 by nonmagnetic Al substitution of Mn
Z. Y. Zhao, M. F. Liu, X. Li +4
The multiferroic RMn2O5 family, where R is rare-earth ion or Y, exhibits rich physics of multiferroicity which has not yet well understood, noting that multiferroicity is receiving…
Localized in-gap state in a single electron doped Mott insulator
Weng-Hang Leong, Shun-Li Yu, T. Xiang +1
Motivated by the recent atomic-scale scanning tunneling microscope (STM) observation for a spatially localized in-gap state in an electron doped Mott insulator, we evaluate the loc…
