Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator
Jian Tang, Thomas Siyuan Ding, Shuhan Ding +24
Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise…
Tunable symmetry breaking in a hexagonal-stacked moiré magnet
Zeliang Sun, Gaihua Ye, Xiaohan Wan +13
Symmetry plays a central role in defining magnetic phases, making tunable symmetry breaking across magnetic transitions highly desirable for discovering non-trivial magnetism. Magn…
Large asymmetric anomalous Nernst effect in the antiferromagnet SrIrSnO
Dongliang Gong, Junyi Yang, Shu Zhang +10
A large anomalous Nernst effect is essential for thermoelectric energy harvesting in the transverse geometry without external magnetic field. It is often connected with anomalous H…
Interplay between topology and correlations in the second moiré band of twisted bilayer MoTe2
Fan Xu, Xumin Chang, Jiayong Xiao +17
Topological flat bands formed in two-dimensional lattice systems offer unique opportunity to study the fractional phases of matter in the absence of an external magnetic field. Cel…
Direct observation of a photoinduced topological phase transition in Bi-doped (Pb,Sn)Se
Masataka Mogi, Dongsung Choi, Louis Primeau +6
Ultrafast photoexcitation offers a novel approach to manipulating quantum materials. One of the long-standing goals in this field is to achieve optical control over topological pro…
