Low-Temperature Pseudogap Phenomenon: Precursor of High- Superconductivity
Yao Ma, Peng Ye, Zheng-Yu Weng
In this paper, we try to understand the pseudogap phenomenon observed in the cuprate superconductor through a model study. Specifically, we explore the so-called low-temperature ps…
Sign structure and ground state properties for a spin- - chain
Qing-Rui Wang, Peng Ye
The antiferromagnetic Heisenberg spin chain of odd spin is in the Haldane phase with several defining physical properties, such as thermodynamical ground-state degeneracy, symm…
Symmetry-protected topological phases with charge and spin symmetries: response theory and dynamical gauge theory in 2D, 3D and the surface of 3D
Peng Ye, Juven Wang
A large class of symmetry-protected topological phases (SPT) in boson / spin systems have been recently predicted by the group cohomology theory. In this work, we consider SPT stat…
Constructing symmetric topological phases of bosons in three dimensions via fermionic projective construction and dyon condensation
Peng Ye, Xiao-Gang Wen
Recently, there is a considerable study on gapped symmetric phases of bosons that do not break any symmetry. Even without symmetry breaking, the bosons can still be in many exotic…
