Twisted bilayer U(1) Dirac spin liquids

Posted by klaurent UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Zhu-Xi Luo, Urban F. P. Seifert, Leon Balents, , | Summary: When two layers of two-dimensional materials are assembled with a relative twist, moir’e patterns arise, inducing a tremendous wealth of exotic phenomena. In this work, we consider twisting two triangular lattices hosting Dirac quantum spin liquids. […]

MVSTER: Epipolar Transformer for Efficient Multi-View Stereo

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Xiaofeng Wang, Zheng Zhu, Fangbo Qin, Yun Ye, Guan Huang | Summary: Learning-based Multi-View Stereo (MVS) methods warp source images into the reference camera frustum to form 3D volumes, which are fused as a cost volume to be regularized by subsequent networks. The fusing step plays a […]

Interplay between Pair Density Wave and a Nested Fermi Surface

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Jin-Tao Jin, Kun Jiang, Hong Yao, Yi Zhou, | Summary: We show that spontaneous time-reversal-symmetry (TRS) breaking can naturally arise from the interplay between pair density wave (PDW) ordering at multiple momenta and nesting of Fermi surfaces (FS). Concretely, we consider pair-density-wave superconductivity on a hexagonal lattice […]
