-Wave Flat Fermi Surface in Altermagnets Enables Maximum Charge-to-Spin Conversion
Junwen Lai, Tianye Yu, Peitao Liu +4
Altermagnets combine antiferromagnetic order with ferromagnet-like spin splitting, a duality that unlocks ultrafast spin-dependent responses. This unique property creates unprecede…
Origin of the charge density wave state in BaFeAl
Yuping Li, Mingfeng Liu, Jiangxu Li +7
Recently, a first-order phase transition associated with charge density wave (CDW) has been observed at low temperatures in intermetallic compound BaFeAl. However, this tra…
Ab-initio study of quantum oscillation in altermagnetic and nonmagnetic phases of RuO
Yingliang Huang, Junwen Lai, Jie Zhan +5
Altermagnet (AM) is a new proposed magnetic state with collinear antiferromagnetic ground state but presents some transport properties that were only believed to exist in ferromagn…
Molecular Beam Epitaxy Growth and Doping Modulation of Topological Semimetal NiTe
Liguo Zhang, Dapeng Zhao, Xiangyang Liu +6
In this study, high-quality thin films of the topological semimetal phase NiTe were prepared using molecular beam epitaxy (MBE) technique, confirmed through X-ray diffraction w…
Electric field tunable non-linear Hall terahertz detector in Dual quantum spin Hall insulator
Junwen Lai, Jie Zhan, Peitao Liu +2
Nonlinear Hall effect (NHE) can be generated via Berry curvature dipole (BCD) on nonequilibrium Fermi surface in a non-magnetic system without inversion symmetry.To achieve a large…
