Length scales of interfacial coupling between metal and insulator phases in oxides

Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone

The characteristic length scale and mechanism of the metal-insulator transition in nickelate superlattices is addressed, with implications for the design of oxide electronics. Controlling phase transitions in transition metal oxides remains a central featu ...

Calculated Drude weight and optical gap across the metal-insulator transition in the RVO3 series (R = Sr, Ca, La, Y)

We studied the changes in the optical properties of the RVO3 series (R = Sr, Ca, La, Y) using band structure calculations. These oxides present a transition from a non-magnetic metallic phase in SrVO3-CaVO3, to an antiferromagnetic insulator state in LaVO3 ...

Topological phonons and thermoelectricity in triple-point metals

Quansheng Wu

Recently published discoveries of acoustic- and optical-mode inversion in the phonon spectrum of certain metals became the first realistic example of noninteracting topological bosonic excitations in existing materials. However, the observable physical and ...

Spectroscopic Studies of the Electronic Structure in Layered Cuprates and Ruthenates

Claudia Giuseppina Fatuzzo

In materials where electrons interact strongly, a number of exotic and exciting phenomena arise. The mechanisms at the base of many of these phenomena remain debated, as strongly correlated electron physics represents one of the biggest challenges for mode ...

Tunable Capacitors and Microwave Filters Based on Vanadium Dioxide Metal-Insulator Transition

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Antonio Paone

We report the fabrication, modeling and characterization of novel microwave tunable capacitors based on the metal-insulator transition (MIT) of Vanadium Dioxide (VO2). We present the advantages of VO2-based capacitors over alternative technologies for micr ...

Opening of a Peierls gap in BaVS3 probed by V L-3 edge resonant inelastic x-ray scattering

Marco Grioni, Thorsten Schmitt, Helmuth Berger, Marco Guarise

V L-3 edge resonant inelastic x-ray scattering measurements performed on high quality BaVS3 single crystals reveal that the intra-t(2g) dd excitations close to the elastic peak are suppressed below the metal-insulator transition induced by the Peierls inst ...

Interacting spin-1 bosons in a two-dimensional optical lattice

We study, using quantum Monte Carlo (QMC) simulations, the ground state properties of spin-1 bosons trapped in a square optical lattice. The phase diagram is characterized by the mobility of the particles (Mott insulating or superfluid phase) and by their ...
