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 ...

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 ...

Tuning the metal-insulator transition in NdNiO3 heterostructures via Fermi surface instability and spin fluctuations

Joël Mesot, Elia Razzoli, Zoran Ristic

We employed in situ pulsed laser deposition (PLD) and angle-resolved photoemission spectroscopy (ARPES) to investigate the mechanism of the metal-insulator transition (MIT) in NdNiO3 (NNO) thin films, grown on NdGaO3(110) and LaAlO3(100) substrates. In the ...

Optical properties of V2O3 in its whole phase diagram

Vanadium sesquioxide V2O3 is considered a textbook example of Mott-Hubbard physics. In this paper, we present an extended optical study of its whole temperature/doping phase diagram as obtained by doping the pure material with M = Cr or Ti atoms (V1-x M-x) ...

Engineering polar discontinuities in honeycomb lattices

Nicola Marzari, Giovanni Pizzi, Marco Gibertini

Unprecedented and fascinating phenomena have been recently observed at oxide interfaces between centrosymmetric cubic materials, where polar discontinuities can give rise to polarization charges and electric fields that drive a metal-insulator transition a ...

Exotic Kondo crossover in a wide temperature region in the topological Kondo insulator SmB6 revealed by high-resolution ARPES

Jan Hugo Dil, Joël Mesot, Kazimierz Conder

Temperature dependence of the electronic structure of SmB6 is studied by high-resolution angle-resolved photoemission spectroscopy (ARPES) down to 1 K. We demonstrate that there is no essential difference for the dispersions of the surface states below and ...

High-temperature Mott transition in wide-band-gap semiconductor quantum wells

Nicolas Grandjean, Jean-François Carlin, Benoît Marie Joseph Deveaud, Raphaël Butté, Jacques Levrat, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Georg Rossbach, Mehran Shahmohammadi

The crossover from an exciton gas to an electron-hole plasma is studied in a GaN/(Al,Ga)N single quantum well by means of combined time-resolved and continuous-wave photoluminescence measurements. The two-dimensional Mott transition is found to be of conti ...

Signatures of quantum criticality in the thermopower of Ba(Fe1-xCox)(2)As-2

László Forró, Richard Gaal, Stevan Arsenijevic

We demonstrate that the thermopower (S) can be used to probe the spin fluctuations (SFs) in proximity to the quantum critical point (QCP) in Fe-based superconductors. The sensitivity of S to the entropy of charge carriers allows us to observe an increase o ...
