Coherent Phonon Pairs and Rotational Symmetry Breaking of Charge Density Wave Order in the Kagome Superconductor CsVSb
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +4
In this work, we perform ultrafast time-resolved reflectivity measurements to study the symmetry breaking in the charge-density wave (CDW) phase of CsVSb. By extracting the…
Direct observation of distinct bulk and edge nonequilibrium spin accumulation in ultrathin MoTe
Fangchu Chen, Kamal Das, Bowen Yang +11
Low-symmetry two-dimensional (2D) topological materials such as MoTe host efficient charge-to-spin conversion (CSC) mechanisms that can be harnessed for novel electronic and sp…
Discovery of transient topological crystalline order in optically driven SnSe
Masataka Mogi, Dongsung Choi, Kyoung Hun Oh +13
Ultrafast optical excitation provides a powerful route for accessing emergent quantum phases far from equilibrium, enabling transient light-induced phenomena such as magnetism, fer…
Altermagnetic band splitting in 10 nm epitaxial CrSb thin films
Sandra Santhosh, Paul Corbae, Wilson J. Yanez-Parreno +14
Altermagnets are a newly identified family of collinear antiferromagnets with momentum-dependent spin-split band structure of non-relativistic origin, derived from spin-group symme…
Revisiting the charge-density-wave superlattice of 1-TiSe
Wei Wang, Patrick Liu, Lijun Wu +4
A number of intriguing phenomena, including exciton condensation, orbital ordering, and emergence of chirality, have been proposed to accompany charge-density-wave (CDW) formation…
Designing Flat Bands, Localized and Itinerant States in TaS2 Trilayer Heterostructures
Hyeonhu Bae, Roser Valenti, Igor I. Mazin +1
Stacking and twisting van der Waals materials provide a powerful tool to design quantum matter and engineer electron correlation. For instance, monolayers of 1T- and 1H-TaS2 are Mo…
