Generic fixed point model for pseudo-spin- quantum dots in nonequilibrium: Spin-valve systems with compensating spin polarizations

Phys. Rev. B 92, 041103(R) (2015) - Published 6 July, 2015
The authors study a generic quantum dot close to the particle-hole symmetric point. By first mapping the model onto an equivalent two-level system coupled to spin-polarized leads, they are able to study the system as a function of magnetic field at large bias voltage. Doing so they are able to identify a non-equilibrium fixed point of the model.

The tungsten ditelluride WTe semimetal is known for if its extremely large magnetoresistance. The authors measure the angular dependence of this magnetoresistance and find that when the magnetic field is applied parallel to the tungsten chains (along the axis), the very large magnetoresistance (as high as 1200% at 15 T and 2 K) no longer exhibits a conventional quadratic but rather a linear field dependence.

Angle-resolved photoemission shows the existence of two-dimensional metallic states of confined itinerant electrons at the (001) and (101) surfaces of insulating TiO anatase. This is a material of much current interest, as a photocatalyst or a transparent conducting oxide, for instance. The 2D electron gases come from the formation of oxygen vacancies in the near-surface region, created by exposure to ultraviolet irradiation. The results here open a route to nano-engineering these confined electronic states using ultraviolet light, controlling their metallic or insulating nature.

Motivated by the question of topological classification in interacting models the authors study an exactly solvable two-leg ladder model of spinless fermions with attractive interactions and find its ground states and correlation functions. They also demonstrate the appearance of topologically protected edge states and derive their braiding properties on a microscopic level.
