Non-local low energy neutral excitations in a strongly disordered triangular Mott magnet CrSeBr
Wenhao Liu, Dechen Zhang, Yuanqi Lyu +13
Understanding if low-energy excitations can remain itinerant in the presence of strong disorder remains a central challenge in frustrated quantum magnets, where disorder is general…
Strain-tunability of the multipolar Berry curvature in altermagnet MnTe
Shane Smolenski, Ning Mao, Dechen Zhang +15
The anomalous Hall effect describes the generation of a transverse voltage by a longitudinal current even in the absence of an external magnetic field. While typically observed in…
Thermoelectric evidence of the electronic structure changes from the charge-density-wave transition in FeGe
Kaila Jenkins, Yuan Zhu, Dechen Zhang +9
Kagome metals provide a material platform for probing new correlated quantum phenomena due to the naturally incorporated linear dispersions, flat bands, and Van Hove singularities…
Quantum oscillations in the heat capacity of Kondo insulator YbB12
Kuan-Wen Chen, Yuan Zhu, Danilo Ratkovski +12
We observe the magnetic quantum oscillation in the heat capacity of the Kondo insulator YbB. The frequency of these oscillations T, aligns with findings from magne…
Unconventional Magnetic Oscillations in Kagome Mott Insulators
Guoxin Zheng, Yuan Zhu, Kuan-Wen Chen +12
In metals, electrons in a magnetic field undergo cyclotron motion, leading to oscillations in physical properties called quantum oscillations. This phenomenon has never been seen i…
Field tunable BKT and quantum phase transitions in spin-1/2 triangular lattice antiferromagnet
Dechen Zhang, Yuan Zhu, Guoxin Zheng +8
Quantum magnetism is one of the most active fields for exploring exotic phases and phase transitions. The recently synthesized Na2BaCo(PO4)2 (NBCP) is an ideal material incarnation…
