Coexistence of Merons with Skyrmions in the Centrosymmetric van der Waals Ferromagnet Fe5GeTe2
Brian W. Casas, Yue Li, Alex Moon +8
FeGeTe is a centrosymmetric, layered van der Waals (vdW) ferromagnet that displays Curie temperatures (270-330 K) that are within the useful range for spintronic…
Anomalously high supercurrent density in a two-dimensional topological material
Qi Zhang, Md Shafayat Hossain, Brian Casas +24
Ongoing advances in superconductors continue to revolutionize technology thanks to the increasingly versatile and robust availability of lossless supercurrent. In particular high s…
Weyl nodal ring states and Landau quantization with very large magnetoresistance in square-net magnet EuGa
Shiming Lei, Kevin Allen, Jianwei Huang +17
Magnetic topological semimetals (TSMs) allow for an effective control of the topological electronic states by tuning the spin configuration, and therefore are promising materials f…
Enhancement of the Residual Linear Term in the Thermal Conductivity of Kondo Insulator SmB6 under Uniaxial Tensile Strain
Brian Casas, Laura Yu, Zachary Fisk +1
Recent experiments on Kondo insulator SmB6 have revealed bulk excitations that could be Fermions without charge. This would lead to a residual linear term in the thermal conductivi…
Room-temperature quantum spin Hall edge state in a higher-order topological insulator BiBr
Nana Shumiya, Md Shafayat Hossain, Jia-Xin Yin +24
Room-temperature realization of macroscopic quantum phenomena is one of the major pursuits in fundamental physics. The quantum spin Hall state, a topological quantum phenomenon tha…
Magnetism and Spin Dynamics in Room-Temperature van der Waals Magnet FeGeTe
Laith Alahmed, Bhuwan Nepal, Juan Macy +12
Two-dimensional (2D) van der Waals (vdWs) materials have gathered a lot of attention recently. However, the majority of these materials have Curie temperatures that are well below…
Direct observation of surface state thermal oscillation in SmB6 oscillators
Brian Casas, Alex Stern, Dmitry K. Efimkin +2
SmB6 is a mixed valence Kondo insulator that exhibits a sharp increase in resistance following an activated behavior that levels off and saturates below 4K. This behavior can be ex…
Topological transitions induced by antiferromagnetism in a thin-film topological insulator
Qing Lin He, Gen Yin, Luyan Yu +14
Ferromagnetism in topological insulators (TIs) opens a topologically non-trivial exchange band gap, providing an exciting platform to manipulate the topological order through an ex…
Topological defects as relics of emergent continuous symmetry and Higgs condensation of disorder in ferroelectrics
Shi-Zeng Lin, Xueyun Wang, Yoshitomo Kamiya +9
Lars Onsager and Richard Feynman envisioned that the three-dimensional (3D) superfluid-to-normal transition in He occurs through the proliferation of vortices. This proce…
