Coexistence of ergodic and weakly ergodic states in finite-height Wannier-Stark ladders
Xingbo Wei, Liangqing Wu, Kewei Feng +2
We investigate a single-particle in one-dimensional Wannier-Stark ladders with either a linear potential or a mosaic potential with spacing . In both cases, we exactly determi…
Kramers nodal lines and Weyl fermions in SmAlSi
Yichen Zhang, Yuxiang Gao, Xue-Jian Gao +16
Kramers nodal lines (KNLs) have recently been proposed theoretically as a special type of Weyl line degeneracy connecting time-reversal invariant momenta. KNLs are robust to spin o…
Three-state nematicity and magneto-optical Kerr effect in the charge density waves in kagome superconductors
Yishuai Xu, Zhuoliang Ni, Yizhou Liu +6
The kagome lattice provides a fascinating playground to study geometrical frustration, topology and strong correlations. The newly-discovered kagome metals AVSb (where A ca…
A new type of cyclotron resonance from charge-impurity scattering in the bulk-insulating BiSe thin films
Xingyue Han, Maryam Salehi, Seongshik Oh +1
This work focuses on the low frequency Drude response of bulk-insulating topological insulator BiSe films. The frequency and field dependence of the mobility and carrier de…
Observation of the superconducting proximity effect from surface states in SmB/YB thin film heterostructures via terahertz spectroscopy
Jonathan Stensberg, Xingyue Han, Seunghun Lee +5
The AC conduction of epitaxially-grown SmB thin films and superconducting heterostructures of SmB/YB are investigated via time domain terahertz spectroscopy. A two-chan…
Direct imaging of antiferromagnetic domains and anomalous layer-dependent mirror symmetry breaking in atomically thin MnPS
Zhuoliang Ni, Huiqin Zhang, David Hopper +8
We have developed a sensitive cryogenic second-harmonic generation microscopy to study a van der Waals antiferromagnet MnPS. We find that long-range Néel antiferromagnetic orde…
