Striped magnetization plateau and chirality-reversible anomalous Hall effect in a magnetic kagome metal
Erjian Cheng, Ning Mao, Xiaotian Yang +19
Kagome materials with magnetic frustration in two-dimensional networks are known for their exotic properties, such as the anomalous Hall effect (AHE) with non-collinear spin textur…
Spectroscopic origin of giant anomalous Hall effect in an interwoven magnetic kagome metal
Erjian Cheng, Kaipu Wang, Yiqing Hao +20
The discovery of a giant anomalous Hall effect (AHE) and its novel mechanism holds significant promise for advancing both fundamental research and practical applications. Magnetic…
Tunable positions of Weyl nodes via magnetism and pressure in the ferromagnetic Weyl semimetal CeAlSi
Erjian Cheng, Limin Yan, Xianbiao Shi +15
The noncentrosymmetric ferromagnetic Weyl semimetal CeAlSi with simultaneous space-inversion (SI) and time-reversal (TR) symmetry breaking provides a unique platform for the explor…
Critical topology and pressure-induced superconductivity in the van der Waals compound AuTe2Br
Erjian Cheng, Xianbiao Shi, Limin Yan +10
The study on quantum spin Hall effect and topological insulators formed the prologue to the surge of research activities in topological materials in the past decade. Compared to in…
Fluctuating magnetic droplets immersed in a sea of quantum spin liquid
Z. H. Zhu, B. L. Pan, L. P. Nie +12
The search of quantum spin liquid (QSL), an exotic magnetic state with strongly-fluctuating and highly-entangled spins down to zero temperature, is a main theme in current condense…
Fermi surface nesting, vacancy ordering and the emergence of superconductivity in IrSb compounds
Tianping Ying, Tongxu Yu, Erjian Cheng +7
Fermi surface nesting, as a peculiar reciprocal space feature, is not only closely correlated with the real space superstructure, but also directly modulates the underlying electro…
Quantum phase transitions and superconductivity in the pressurized heavy-fermion compound CeCuP2
Erjian Cheng, Chuchu Zhu, Tianping Ying +8
The tilted balance among competing interactions can yield a rich variety of ground states of quantum matter. In most Ce-based heavy fermion systems, this can often be qualitatively…
Multiple Weyl fermions in the noncentrosymmetric semimetal LaAlSi
Hao Su, Xianbiao Shi, Jian Yuan +10
The noncentrosymmetric RAlPn (R = rare earth, Pn = Si, Ge) family, predicted to host nonmagnetic and magnetic Weyl states, provide an excellent platform for investigating the relat…
Magnetism-induced topological transition in EuAs3
Erjian Cheng, Wei Xia, Xianbiao Shi +15
The nature of the interaction between magnetism and topology in magnetic topological semimetals remains mysterious, but may be expected to lead to a variety of novel physics. We pr…
Pressure-induced superconductivity and topological phase transitions in the topological nodal-line semimetal SrAs3
E. J. Cheng, W. Xia, X. B. Shi +16
Topological nodal-line semimetals (TNLSMs) are materials whose conduction and valence bands cross each other, meeting a topologically-protected closed loop rather than discrete poi…
Type-I superconductivity in AlRe
Darren C. Peets, Erjian Cheng, Tianping Ying +4
While the pure elements tend to exhibit Type-I rather than Type-II superconductivity, nearly all compound superconductors are Type-II, with only a few known exceptions. We report s…
Magnetotransport in Al6Re
Erjian Cheng, Darren C. Peets, Chuanying Xi +3
Since very few Type-I superconductors are known and most are elemental superconductors, there are very few experimental platforms where the interaction between Type-I superconducti…
Route to chaos in a coupled microresonator system with gain and loss
Krzysztof Zegadlo, Nguyen Viet Hung, Vladimir V. Konotop +2
We consider chaotic dynamics of a system of two coupled ring resonators with a linear gain and a nonlinear absorption. Such a structure can be implemented in various settings inclu…
Ultralow-temperature thermal conductivity of Pr2Ir2O7: a metallic spin-liquid candidate with quantum criticality
J. M. Ni, Y. Y. Huang, E. J. Cheng +6
The frustrated pyrochlore iridate PrIrO was proposed as a metallic quantum spin liquid located at a zero-field quantum critical point. Here we present the ultralow-temp…

We grew the single crystals of the SnAs-based van der Waals (vdW)-type superconductor NaSnAs and systematically measured its resistivity, specific heat, and ultralow-temper…
Discrete superconducting phases in FeSe-derived superconductors
T. P. Ying, M. X. Wang, Z. Y. Zhao +12
A general feature of unconventional superconductors is the existence of a superconducting dome in the phase diagram as a function of carrier concentration. For the simplest iron-ba…
