High-temperature superconductivity

Despite decades of theoretical and experimental effort, a microscopic theory of high-temperature superconductivity is still missing. We explore the current status and future of this field.


    • The Weyl orbit is a type of cyclotron orbit that appears in topological semimetals. This Perspective discusses the Weyl orbit in the context of the 3D quantum Hall effect and provides an outlook on new phenomena that can arise from these states.

    • Magnetic molecules have been widely proposed for different quantum technologies due to their bewildering quantum properties. This Review describes techniques of paramount importance for the characterization, understanding and, ultimately, manipulation of the electronic properties of these systems.

    • Phonon heat conduction at the microscale and the nanoscale exhibits rich phenomena beyond the predictions of Fourier’s law, rivalling the phenomena of electrons. This Review discusses phonon heat conduction regimes, including the Casimir–Knudsen size effect, hydrodynamic transport, coherent transport (from quantization and localization) and divergence.
