Rational tensegrities through the lens of toric geometry
Fatemeh Mohammadi, Xian Wu
A classical tensegrity model consists of an embedded graph in a vector space with rigid bars representing edges, and an assignment of a stress to every edge such that at every vert…
Non-trivial band topology and orbital-selective electronic nematicity in a new titanium-based kagome superconductor
Yong Hu, Congcong Le, Zhen Zhao +11
Electronic nematicity that spontaneously breaks rotational symmetry has been shown as a generic phenomenon in correlated quantum systems including high-temperature superconductors…
Crossover between electron-electron and electron-phonon mediated pairing on the Kagome lattice
Xianxin Wu, Debmalya Chakraborty, Andreas P. Schnyder +1
We study electron-electron and electron-phonon mediated pairing in the Holstein extended Hubbard model on the Kagome lattice near the van Hove fillings, and investigate their combi…
Identifying -wave pairing symmetry in single-layer FeSe from topologically trivial edge states
Zhongxu Wei, Shengshan Qin, Cui Ding +4
Determining the pairing symmetry of single-layer FeSe on SrTiO is the key to understanding the enhanced pairing mechanism; furthermore, it guides exploring new superconductors…
DeepPortraitDrawing: Generating Human Body Images from Freehand Sketches
Xian Wu, Chen Wang, Hongbo Fu +3
Researchers have explored various ways to generate realistic images from freehand sketches, e.g., for objects and human faces. However, how to generate realistic human body images…
Tunable Topological Dirac Surface States and Van Hove Singularities in Kagome Metal GdVSn
Yong Hu, Xianxin Wu, Yongqi Yang +6
Transition-metal-based kagome materials at van Hove filling are a rich frontier for the investigation of novel topological electronic states and correlated phenomena. To date, in t…
