including electron hydrodynamics, quantum field theoretic anomalies, and extreme …

Electron–phonon coupling is crucial for the existence of various phases of matter, in
particular superconductivity and density waves. Here, we devise a theory that incorporates …

High-performance terahertz wave detectors at room temperature are still urgently required
for a wide range of applications. The available technologies, however, are plagued by low …

Nontrivial band topologies in semimetals lead to robust surface states that can contribute
dominantly to the total conduction. This may result in reduced resistivity with decreasing …

Photodetection is an indispensable function of optoelectronic devices in modern
communication and sensing systems. Contrary to the near-infrared/visible regions, the fast …

Weyl semimetals (WSMs) exhibit an electronic structure governed by linear band
dispersions and degenerate (Weyl) points that lead to exotic physical phenomena. While …

We show that Weyl Fermi arcs are generically accompanied by a divergence of the surface
Berry curvature scaling as 1/k 2, where k is the distance to a hot line in the surface Brillouin …
