Free-electron gas at charged domain walls in insulating BaTiO3

Alexander Tagantsev, Nava Setter, Tomas Sluka, Petr Bednyakov

Hetero interfaces between metal-oxides display pronounced phenomena such as semiconductor-metal transitions, magnetoresistance, the quantum hall effect and superconductivity. Similar effects at compositionally homogeneous interfaces including ferroic domai ...

Two-dimensional short-range interacting attractive and repulsive Fermi gases at zero temperature

Gianluca Bertaina

We study a two-dimensional two-component Fermi gas with attractive or repulsive short-range interactions at zero temperature. We use Diffusion Monte Carlo with Fixed Node approximation in order to calculate the energy per particle and the opposite spin pai ...

Quantum oscillations and optical conductivity in Rashba spin-splitting BiTeI

Helmuth Berger

We report the observation of Shubnikov-de Haas oscillations in single crystals of the Rashba spin-splitting compound BiTeI, from both longitudinal [R-xx(B)] and Hall [R-xy(B)] magnetoresistance. Under magnetic fields up to 65 T, we resolved unambiguously o ...

Lifting degeneracies in Higgs couplings using single top production in association with a Higgs boson

Andrea Thamm

Current Higgs data show an ambiguity in the value of the Yukawa couplings to quarks and leptons. Not so much because of still large uncertainties in the measurements but as the result of several almost degenerate minima in the coupling profile likelihood f ...

Curvature effects on valley splitting and degeneracy lifting: Case of Si/Ge rolled-up nanotubes

Giovanni Pizzi

We numerically investigate electronic states, degeneracy lifting, and valley splitting in the conduction band of rolled-up Si/Ge nanotubes. Results are derived from a tight-binding model where the input equilibrium positions of the atoms are obtained by me ...
