Uniaxial strain tuning of charge modulation and singularity in a kagome superconductor.

Tunable quantum materials hold great potential for applications. Of special interest are materials in which small lattice strain induces giant electronic responses. The kagome compounds AVSb (A = K, Rb, Cs) provide a testbed for electronic tunable states.

Evaluation of the Accuracy of Electronic Apex Locators in Modern Endodontics: An Umbrella Review.

To achieve success in endodontic treatment, it is essential to properly perform the steps of shaping, cleansing and obturation. Determining the working length of the canal is, therefore, a process that must be precise and accurate. Electronic apex locators are a useful tool for the clinician to best perform this step of endodontic treatment.

Edge Zeros and Boundary Spinons in Topological Mott Insulators.

We use a real-space slave-rotor theory of the physics of topological Mott insulators, using the Kane-Mele-Hubbard model as an example, and show that a topological gap in the Green function zeros corresponds to a gap in the bulk spinon spectrum and implies a gapless band of edge zeros and a spinon edge mode. We then consider an interface between a topological Mott insulator and a conventional topological insulator showing how the spinon edge mode of the topological Mott insulator combines with the spin part of the conventional electron topological edge state, leaving a non-Fermi liquid edge mode described by a gapless propagating holon and gapped spinon state. Our work demonstrates the physical meaning of Green function zeros and shows that interfaces between conventional and Mott topological insulators are a rich source of new physics.
