Synthesis of layered gold tellurides AuSbTe and Au$_2$Te$_3$ and their semiconducting and metallic behavior

Kavli Affiliate: Cheng Peng | First 5 Authors: Emma A. Pappas, Rong Zhang, Cheng Peng, Robert T. Busch, Jian-Min Zuo | Summary: Previous studies on natural samples of pampaloite (AuSbTe) revealed the crystal structure of a potentially cleavable and/or exfoliable material, while studies on natural and synthetic montbrayite (Sb-containing Au$_2$Te$_3$) claimed various chemical compositions for […]

Spin Supersolid Phase and Double Magnon-Roton Excitations in a Cobalt-based Triangular Lattice

Kavli Affiliate: Gang Su | First 5 Authors: Yuan Gao, Chuandi Zhang, Junsen Xiang, Dehong Yu, Xingye Lu | Summary: Supersolid is an exotic quantum state of matter that hosts spontaneously the features of both solid and superfluidity, which breaks the lattice translational symmetry and U(1) gauge symmetry. Here we conduct inelastic neutron scattering (INS) […]

Runtime-coherence trade-offs for hybrid SAT-solvers

Kavli Affiliate: David Gross | First 5 Authors: Vahideh Eshaghian, Sören Wilkening, Johan Åberg, David Gross, | Summary: Many search-based quantum algorithms that achieve a theoretical speedup are not practically relevant since they require extraordinarily long coherence times, or lack the parallelizability of their classical counterparts.This raises the question of how to divide computational tasks […]

DMesh: A Differentiable Representation for General Meshes

Kavli Affiliate: Yi Zhou | First 5 Authors: Sanghyun Son, Matheus Gadelha, Yang Zhou, Zexiang Xu, Ming C. Lin | Summary: We present a differentiable representation, DMesh, for general 3D triangular meshes. DMesh considers both the geometry and connectivity information of a mesh. In our design, we first get a set of convex tetrahedra that […]

Effect of disorder on Berry curvature and quantum metric in two-band gapped graphene

Kavli Affiliate: Gang Su | First 5 Authors: Ze Liu, Zhi-Fan Zhang, Zhen-Gang Zhu, Gang Su, | Summary: The geometric properties of parameter space are mostly described by Berry curvature and quantum metric, which is the imaginary and real part of quantum geometric tensor, respectively. In this work, we calculate the dressed Berry curvature and […]
