Mott insulators are distinguished by their electrical resistivity, which remains exceedingly high even as temperature approaches absolute zero. This behavior defies the conventional understanding of electrical conductivity and has puzzled researchers for decades. Correlated metals, on the other hand, exhibit unusual electronic properties that stem from strong electron-electron interactions.

Spectroscopy techniques, such as optical conductivity, angle-resolved photoemission spectroscopy, resonant inelastic X-ray scattering, and spin-polarized photoemission spectroscopy, provide invaluable tools for probing the microscopic world of Mott insulators and correlated metals. These techniques allow researchers to investigate the electronic structure, spin dynamics, and other fundamental properties that govern the behavior of these materials.

Unveiling the Hidden Structure: Optical Conductivity

Optical conductivity spectroscopy measures the response of materials to electromagnetic radiation. By analyzing the absorption and scattering of light, researchers can gain insights into the electronic excitations and charge carrier dynamics within the material.

In Mott insulators, optical conductivity reveals the presence of a characteristic energy gap separating the occupied and unoccupied electronic states. This gap originates from the strong electron-electron interactions that prevent electrons from hopping between atomic sites.

Mapping the Electronic Landscape: Angle-Resolved Photoemission Spectroscopy

Angle-resolved photoemission spectroscopy (ARPES) is a powerful technique for visualizing the electronic band structure of materials. By measuring the energy and momentum of photoemitted electrons, ARPES provides a detailed map of the occupied electronic states.

In correlated metals, ARPES reveals the presence of unusual electronic bands, such as flat bands and Fermi arcs. These features are indicative of strong electron-electron interactions and can provide insights into the material's superconducting or other novel properties.

Exploring Spin Dynamics: Resonant Inelastic X-Ray Scattering

Resonant inelastic X-ray scattering (RIXS) is a unique spectroscopy technique that probes the spin excitations and magnetic interactions within materials. By tuning the X-ray energy to a specific electronic resonance, RIXS can reveal the energy and momentum of spin waves and other magnetic excitations.

In Mott insulators, RIXS has been instrumental in understanding the nature of magnetism and the interplay between spin and charge degrees of freedom. This knowledge is crucial for unraveling the mechanisms behind quantum phase transitions and other complex magnetic phenomena.

Uncovering Spin Polarization: Spin-Polarized Photoemission Spectroscopy

Spin-polarized photoemission spectroscopy (SP-PES) is a specialized technique that measures the spin polarization of photoemitted electrons. This information provides insights into the spin texture of the material's electronic states and the magnetic properties that arise from electron spin.

In correlated metals, SP-PES has helped elucidate the role of spin-orbit coupling and its influence on the electronic properties. This understanding is essential for exploring the potential of these materials in spintronics and other emerging technologies.
