The search for topological phases of matter is evolving towards strongly interacting systems,
including magnets and superconductors, where exotic effects emerge from the quantum …

The superconductor iron selenide (FeSe) is of intense interest owing to its unusual
nonmagnetic nematic state and potential for high-temperature superconductivity. But its …

The scanning tunnelling microscope (STM) was invented by Binnig and Rohrer and
received a Nobel Prize of Physics in 1986. Together with the atomic force microscope (AFM) …

Tunneling spectroscopy has played a central role in the experimental verification of the
microscopic theory of superconductivity in classical superconductors. Initial attempts to apply …

Nitrogen-vacancy (NV) centers in diamond can be used as quantum sensors to image the
magnetic field with nanoscale resolution. However, nanoscale electric-field mapping has not …

Although the crystal structures of the copper oxide high-temperature superconductors are
complex and diverse, they all contain some crystal planes consisting of only copper and …

The Cooper pairing mechanism of heavy fermionsuperconductors,,,, long thought to be due
to spin fluctuations,,, has not yet been determined. It is the momentum space (k-space) …

The performance of qubit-based technologies can be strongly limited by environmental
sources of noise and disorder that cause decoherence. Qubits used in quantum sensing are …

In the first three years since the discovery of Fe-based high T c superconductors, scanning
