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 ...

Microscopic evidence for strong periodic lattice distortion in two-dimensional charge-density wave systems

Helmuth Berger, Ji Dai

In quasi-two-dimensional electron systems of layered transition metal dichalcogenides (TMDs) there is still controversy about the nature of the transitions to charge-density wave (CDW) phases, i.e., whether they are described by a Peierls-type mechanism or ...

Direct observation of the spin texture in SmB6 as evidence of the topological Kondo insulator

Jan Hugo Dil, Joël Mesot, Stefan Peter Muff, Kazimierz Conder

Topological Kondo insulators have been proposed as a new class of topological insulators in which non-trivial surface states reside in the bulk Kondo band gap at low temperature due to strong spin-orbit coupling. In contrast to other three-dimensional topo ...

Magnetic order in the 2D Heavy-Fermion system CePt2In7 studied by mu+SR

Marco Grioni, Kamil Sedlák, Martin Mansson, Krunoslav Prsa

The low-temperature microscopic magnetic properties of the quasi-2D heavy-fermion compound, CePt2In7 are investigated by using a positive muon-spin rotation and relaxation (mu+SR) technique. Clear evidence for the formation of a commensurate antiferromagne ...

Biexcitonic molecules survive excitons at the Mott transition

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

When the carrier density is increased in a semiconductor, according to the predictions of Sir Nevil Mott, a transition should occur from an insulating state consisting of a gas of excitons to a conductive electron-hole plasma. This crossover, usually refer ...

Anisotropic softening of magnetic excitations along the nodal direction in superconducting cuprates

Henrik Moodysson Rønnow, Marco Grioni, Thorsten Schmitt, Helmuth Berger, Marco Guarise, Bastien Dalla Piazza

The high-T-c cuprate superconductors are close to antiferromagnetic order. Recent measurements of magnetic excitations have reported an intriguing similarity to the spin wavesmagnons- of the antiferromagnetic insulating parent compounds, suggesting that ma ...

Intermittent dewetting and dryout of annular flows

John Richard Thome, Navid Borhani

Flow visualisation of saturated flow boiling of refrigerant R245fa in a silicon parallel multi-microchannel evaporator, at low mass flux and moderate uniform heat flux, has been carried out with a high-speed digital camera. Using the time-strip technique t ...

Asymmetry of collective excitations in electron- and hole-doped cuprate superconductors

Sandrine Gerber, Thorsten Schmitt, Gang Yu

High-temperature superconductivity emerges on doping holes or electrons into antiferromagnetic copper oxides. The large energy scale of magnetic excitations, for example, compared with phonon energies, is thought to drive superconductivity with high transi ...
