Emergent Chiral Spin Crystal Phase in (111) SrRuO3 Thin Films
Zhaoqing Ding, Yongjie Xie, Xuejiao Chen +13
Perovskite ruthenates are fascinating playgrounds for exploring topological spin textures, but generally rely on extrinsic mechanisms to trigger the noncoplanar states. Here we rep…
Optical Excitations of Flat Bands Induced by Exciton Condensation in TaPdTe
Shaohui Yi, Zhiyu Liao, Chenhao Liang +10
We report on the charge dynamics of TaPdTe using temperature-dependent optical spectroscopy with polarized light. We observe a metal-insulator transition characterized…
Unraveling the origin of Kondo-like behavior in the 3-electron heavy-fermion compound YFeGe
Bing Xu, Rui Liu, Hongliang Wo +7
The heavy fermion (HF) state of -electron systems is of great current interest since it exhibits various exotic phases and phenomena that are reminiscent of the Kondo effect in…
Ferroelectricity in undoped HfO2 down to one-unit-cell on Si substrate
Tiantian Wang, He Zhang, Yongjie Xie +12
Hafnium oxide (HfO2), particularly at low-dimensional scales, exhibits extensive promising applications in ultrahigh density devices like low-power logic and non-volatile memory de…
Spectroscopic signatures of magnetization-induced band renormalization and strong spin-charge-lattice coupling in EuZnAs
Zhiyu Liao, Boxuan Li, Shaohui Yi +9
We report an infrared spectroscopy study of the antiferromagnetic (AFM) insulator EuZnAs over a broad frequency range, spanning temperatures both above and below the AFM tr…
Charge Dynamics of an Unconventional Three-Dimensional Charge Density Wave in Kagome FeGe
Shaohui Yi, Zhiyu Liao, Qi Wang +10
We report on the charge dynamics of kagome FeGe, an antiferromagnet with a charge density wave (CDW) transition at K, using polarized infrared spectro…
Surface skyrmions and dual topological Hall effect in antiferromagnetic topological insulator EuCdAs
Min Wu, R. Yang, Xiangde Zhu +17
In this work, we synthesized single crystal of EuCdAs, which exhibits A-type antiferromagnetic (AFM) order with in-plane spin orientation below = 9.5~K.Optical spectr…
Visualization of Skyrmion-Superconducting Vortex Pairs in a Chiral-Magnet-Superconductor Heterostructure
Yong-Jie Xie, Ang Qian, Bin He +6
Magnetic skyrmions, the topological states possessing chiral magnetic structure with nontrivial topology, have been widely investigated as a promising candidate for spintronic devi…
Photocurrent-driven transient symmetry breaking in the Weyl semimetal TaAs
N Sirica, P. P. Orth, M. S. Scheurer +23
Symmetry plays a central role in conventional and topological phases of matter, making the ability to optically drive symmetry change a critical step in developing future technolog…
