Chemists have made tremendous advances in synthesizing a variety of nanostructures with control over their size, shape, and chemical composition. Plus, it is possible to control their assembly and to make macroscopic materials. Combined, these advances suggest an opportunity to “nanoengineer” materials ie controllably fabricate materials from the nanoscale up with a wide range of controlled...

While most experimental and theoretical clues lean towards a magnetic origin for the pairing mechanism of cuprates, the question of its degree of retardation in the strong correlation regime remains highly controversial.[1,2] The answer to this question lies partly in the frequency dependence of the anomalous spectral function of doped Mott insulators, extracted at finite temperature via the...

The state of an Anderson localized system can be described in terms of the occupation of a set of single-particle wave functions which are localized in space. When interactions are added, single-particle wave functions are no longer well defined, so what is a useful description of the state of a many-body localized system and what about it is localized? Given that any system with...

We have measured resistivity vs. temperature and pressure on the fluoro-substituted oxobenzene-bridged bisdithiazolyl radical, FBBO. This is a layered, single component organic compound that is a Mott insulator at ambient pressure, due to the singly occupied molecular orbitals and an intrinsically high inter-molecular charge transfer energy barrier. Previous room temperature infrared...

The honeycomb lattice iridate Li2IrO3 displays a novel J_eff = 1/2 Mott insulating ground state driven by strong 5d spin-orbit coupling effects. Due to a combination of J_eff = 1/2 magnetic moments, 90 degree Ir-O-Ir bond geometry, and honeycomb lattice crystal structure, Li2IrO3 represents one of the most promising candidates for the experimental realization of the Kitaev model. This...

Rare-earth orthoferrites, RFeO3 where R is Y or rare earth elements with perovskite structure exhibit intriguing magnetic properties, including non-collinear structures and magnetic phase transitions due to a combination of antiferromagnetic (AFM) exchange interactions and Dzyaloshinsky-Moriya (DM) anti-symmetric exchange interactions, which make them promising candidates for innovative...

In integrable quantum many-body systems exact results for the ground state and the thermodynamic properties can be derived. These results are an important building block in our understanding of quantum systems with strong correlations. They are also a point of reference to judge the quality of approximative analytical and numerical approaches. Within the last years, a number of experiments on...
