High-order coupling as a driver for Mott insulating behavior in Holography
Lin-Yue Bai, René Meyer, Zhen-Hua Zhou
We construct a simple holographic model incorporating higher-order coupling terms for electron self-interactions. It can exhibit typical behavior of a Mott insulator, including a m…

Topological magnons in a non-coplanar magnetic order on the triangular lattice
Linli Bai, Ken Chen
The bond-dependent Kitaev interaction is familiar in the effective spin model of transition metal compounds with octahedral ligands. In this work, we find a peculiar non-coplan…

Transport properties of a holographic model with novel gauge-axion coupling
Lin-Yue Bai, Jian-Pin Wu, Zhen-Hua Zhou
We investigate the transport properties within a holographic model characterized by a novel gauge-axion coupling. A key innovation is the introduction of the direct coupling betwee…
