Symmetry Constraints on Direct-Current Josephson Diodes
Da Wang, Qiang-Hua Wang, Congjun Wu
It is necessary to break both time-reversal and parity symmetries to realize a Josephson, or superconducting, diode exhibiting nonreciprocal critical direct-currents (DC). In fact,…
Tunable quantum criticalities in an isospin extended Hubbard model simulator
Qiao Li, Bin Cheng, Moyu Chen +13
Studying strong electron correlations has been an essential driving force for pushing the frontiers of condensed matter physics. In particular, in the vicinity of correlation-drive…
Transition from band insulator to Mott insulator and formation of local moment in half-filled ionic SU() Hubbard model
Shan-Yue Wang, Da Wang, Qiang-Hua Wang
We investigate the local moment formation in the half-filled SU() Hubbard model under a staggered ionic potential. As the Hubbard increases, the charge fluctuations are supp…
Reply to "Comment on 'Anisotropic Scattering Caused by Apical Oxygen Vacancies in Thin Films of Overdoped High Temperature Cuprate Superconductors'"
Da Wang, Jun-Qi Xu, Hai-Jun Zhang +1
In our recent work [Phys. Rev. Lett. 128, 137001 (2002)], we proposed that the apical oxygen vacancies act as anisotropic scattering impurities. Within the Born approximation, this…
Determinant quantum Monte Carlo for the half-filled Hubbard model with nonlocal density-density interactions
Meng Yao, Da Wang, Qiang-Hua Wang
We design a novel formalism of determinant quantum Monte Carlo method for the half-filled Hubbard model with on-site Hubbard interaction and nearest neighbor density-density in…
Magnetotransport in overdoped LaSrCuO: Effect of anisotropic scattering
Rui-Ying Mao, Da Wang, Qiang-Hua Wang
We revisit the Hall effect and magnetoresistivity by incorporating the anisotropic scattering caused by apical oxygen vacancies in overdoped La-based cuprates. The theoretical calc…
