Gate tuning of coupled electronic and structural phase transition in atomically thin TaNiSe
Keyu Wei, Yixuan Luo, Kenji Watanabe +3
Realizing an excitonic insulator phase from narrow-gap semiconductors remains challenging, as unambiguous experimental signatures are difficult to establish. TaNiSe has bee…
Sliding two-dimensional superconductivity and charge-density-wave state in a bulk crystal
Xiangqi Liu, Chen Xu, Jing Jiang +26
Superconductivity in the two-dimensional (2D) limit is a fertile ground for exotic quantum phenomena-many of which remain elusive in their 3D counterparts. While studies of 2D supe…
The interplay of ferroelectricity and magneto-transport in non-magnetic moiré superlattices
Siqi Jiang, Renjun Du, Jiawei Jiang +20
The coupling of ferroelectricity and magnetic order provides rich tunability for engineering material properties and demonstrates great potential for uncovering novel quantum pheno…
Unveiling resilient superconducting fluctuations in atomically thin NbSe through Higgs mode spectroscopy
Yu Du, Gan Liu, Wei Ruan +6
We report a combined electrical transport and optical study of the superconductivity in atomically thin NbSe. When subjected to an out-of-plane magnetic field, an anomalous met…
