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…
