Spintronics, being a part of electronics, is under intense development for about forty years
and mainly concerns transport of electronics spin in low-dimensional structures. This field …

Starting from exact eigenstates for a symmetric ring, we derive a low-energy effective
generalized Anderson Hamiltonian which contains two spin doublets with opposite …

Using different techniques, and Fermi-liquid relationships, we calculate the variation with the
applied magnetic field (up to second order) of the zero-temperature equilibrium conductance …

We study the quantum phase transition (QPT) and electronic transport in triple quantum dots
for a wide range of the gate voltage epsilon. We focus on the effect of the interdot repulsion …

We propose a new type of chiral metamaterial based on an ensemble of artificial molecules
formed by three identical quantum dots in a triangular arrangement. A static magnetic field …

By means of the numerical renormalization group (NRG) technique, we study the low
temperature transport property and the phase transition for a triangular triple quantum dot …

Cutting edge research in modern solid state physics is characterized on the one hand by
highly complex systems with various interactions between quasi-particles. In this context …

The quantum phase transition and the electronic transport in a triangular quantum dot
system are investigated using the numerical renormalization group method. We concentrate …

After obtaining an exact analytical time-varying solution for the Aharonov–Casher
conducting ring embedded in a textured static/dynamic electric field, we investigate the spin …
