Imaging phonon-mediated hydrodynamic flow in WTe2
Uri Vool, Assaf Hamo, Georgios Varnavides +12
In the presence of interactions, electrons in condensed-matter systems can behave hydrodynamically, exhibiting phenomena associated with classical fluids, such as vortices and Pois…
Detection of antiskyrmions by topological Hall effect in Heusler compounds
Vivek Kumar, Nitesh Kumar, Manfred Reehuis +7
Heusler compounds having crystal symmetry gained much attention recently due to the stabilization of a vortex-like spin texture called antiskyrmions in thin l…
Large Nernst Power Factor over a Broad Temperature Range in Polycrystalline Weyl Semimetal NbP
Chenguang Fu, Satya N. Guin, Sarah J. Watzman +10
The discovery of topological materials has provided new opportunities to exploit advanced materials for heat-to-electricity energy conversion as they share many common characterist…
Synergistically creating sulfur vacancies in semimetal-supported amorphous MoS2 for efficient hydrogen evolution
Guowei Li, Chenguang Fu, Jiquan Wu +14
The presence of elemental vacancies in materials is inevitable according to statistical thermodynamics, which will decide the chemical and physical properties of the investigated s…
Tetragonal superstructure of the antiskyrmion hosting Heusler compound Mn1.4PtSn
Praveen Vir, Nitesh Kumar, Horst Borrmann +4
Skyrmions in non-centrosymmetric magnets are vortex-like spin arrangements, viewed as potential candidates for information storage devices. The crystal structure and non-collinear…
Zero-field Nernst effect in a ferromagnetic kagome-lattice Weyl-semimetal Co3Sn2S2
Satya N. Guin, Praveen Vir, Yang Zhang +10
The discovery of magnetic topological semimetals recently attracted significant attention in the field of topology and thermoelectrics. In a thermoelectric device based on the Nern…
