Free-fermion Entanglement Spectrum through Wannier Interpolation
Ching Hua Lee, Peng Ye
Quantum Entanglement plays an ubiquitous role in theoretical physics, from the characterization of novel phases of matter to understanding the efficacy of numerical algorithms. As…
Vortex-line condensation in three dimensions: A physical mechanism for bosonic topological insulators
Peng Ye, Zheng-Cheng Gu
Bosonic topological insulators (BTI) in three dimensions are symmetry-protected topological phases (SPT) protected by time-reversal and boson number conservation {symmetries}. BTI…
Symmetry Protected Topological Order in Gutzwiller Wave Functions
Zheng-Xin Liu, Jia-Wei Mei, Peng Ye +1
Gutzwiller projection is a way to construct many-body wave functions that could carry topological order or symmetry protected topological (SPT) order. However, an important issue i…
Position momentum Duality in the Entanglement Spectrum of Free Fermions
Ching Hua Lee, Peng Ye, Xiao-Liang Qi
We propose an exact equivalence between the entanglement spectra of two completely different free-fermion systems at zero temperature. This equivalence follows from a position-mome…
