Quadratic piezoelectricity from stacking-engineered interference in multilayer sliding ferroelectrics
Jiaxuan Fan, Yuexing Zhao, Xiao-Ping Li +3
Designing nonlinear piezoelectricity requires suppressing the linear piezoelectric coefficient without extinguishing higher-order electromechanical response, yet a general and reco…
Charge-Density-Wave Phase Selection by Janus-Induced Intrinsic Strain in Monolayer NbSSiAs
Chun-Jie Zhang, Bing Zhang, Dongliang Mao +3
Controlling phase selection among competing charge-density-wave (CDW) instabilities remains challenging in two-dimensional materials. Here, first-principles calculations show that…
Symmetry-Selective Strain Control of Spin-Momentum Locking and Spin Transport in Two-Dimensional Pentagonal Altermagnets
ShuaiYu Wang, Sheng Chen, Xiao-Ping Li +1
Altermagnets are compensated magnets featuring momentum-dependent nonrelativistic spin splitting generated by nontrivial operations connecting opposite-spin sublattices. A direct s…
Enhanced superconductivity in atomically thin noble metals: From quantum confinement to interface-induced Lifshitz transition
Chun-Jie Zhang, Bing Zhang, Yapeng Wu +2
Unlocking superconductivity in intrinsically non-superconducting noble metals (Au, Ag, Cu) represents a fundamental challenge in low-dimensional physics. While quantum confinement…
Weyl-Dirac nodal line phonons with type-selective surface states
Le Du, Zeling Li, Jiabing Chen +3
The band complex formed by multiple topological states has attracted extensive attention for the emergent properties produced by the interplay among the constituent states. Here, b…
Manipulating Anomalous Transport via Crystal Symmetry in 2D Altermagnets
Dan Li, Shuaiyu Wang, Jiabin chen +7
Anomalous transports, including the anomalous Hall effect (AHE) and anomalous Nernst effect (ANE), are typical manifestations of time-reversal-symmetry-breaking responses in materi…
