Stripe order in the doped Hubbard model on the honeycomb lattice
Xu Yang, Hao Zheng, Mingpu Qin
We study the ground state properties of the doped Hubbard model with strong interactions on honeycomb lattice by the Density Matrix Renormalization Group (DMRG) method. At half-fil…
Nonreciprocal directional dichroism induced by a temperature gradient as a probe for mobile spin dynamics in quantum magnets
Xu Yang, Ying Ran
Novel states of matter in quantum magnets like quantum spin liquids attract considerable interest recently. Despite the existence of a plenty of candidate materials, there is no co…
Non-Kitaev spin liquids in Kitaev materials
Yao Dong Li, Xu Yang, Yi Zhou +1
We point out that the Kitaev materials may not necessarily support Kitaev spin liquid. It is well-known that having a Kitaev term in the spin interaction is not the sufficient cond…
Bosonic SET to SPT Transition under Dyonic LSM Theorem
Yan-Cheng Wang, Xu Yang, Ying Ran +1
Employing large-scale quantum Monte Carlo simulatoins, we study the phase diagram of a quantum spin model which is subject to the recently developed dyonic Lieb-Shultz-Mattis (LSM)…
Dyonic Lieb-Shultz-Mattis Theorem and Symmetry Protected Topological Phases in Decorated Dimer Models
Xu Yang, Shenghan Jiang, Ashvin Vishwanath +1
We consider 2+1D lattice models of interacting bosons or spins, with both magnetic flux and fractional spin in the unit cell. We propose and prove a modified Lieb-Shultz Mattis (LS…
Schwinger boson spin liquid states on square lattice
Xu Yang, Fa Wang
We study possible spin liquids on square lattice that respect all lattice symmetries and time-reversal symmetry within the framework of Schwinger boson (mean-field) theory. Such sp…
