3D Quantum Hall Effect with Two Distinct Plateaus
Jun-Hong Li, Yi-Yuan Chen, Peng-Lu Zhao +2
The recent discovery of the 3D quantum Hall effect in has also revealed puzzling signatures of possible 3D fractionalization. Beyond the first plateau associated…
Nernst Plateau in the Quantum Limit of Low-Carrier-Density Topological Insulators
Peng-Lu Zhao, J. L. Zhang, Hai-Zhou Lu +1
Nernst effect, a transverse electric current induced by a temperature gradient, is a promising tool for revealing emergent phases of condensed matter. We find a Nernst coefficient…
Emergence of Nodal-Knot Transitions by Disorder
Ming Gong, Peng-Lu Zhao, Hai-Zhou Lu +2
Under certain symmetries, degenerate points in three-dimensional metals form one-dimensional nodal lines. These nodal lines sometimes exhibit intricate knotted structures and have…
Observation of Giant Nernst plateau in ideal 1D Weyl Phase
Yong Zhang, Qi Li, Penglu Zhao +7
The search for a giant Nernst effect beyond conventional mechanisms offers advantages for developing advanced thermoelectric devices and understanding charge-entropy conversion. He…
