Metal-insulator transition in a quantum wire driven by a modulated Rashba spin-orbit coupling
G. I. Japaridze, Henrik Johannesson, Alvaro Ferraz
We study the ground-state properties of electrons confined to a quantum wire and subject to a smoothly modulated Rashba spin-orbit coupling. When the period of the modulation becom…
Multicriticality and entanglement in the one-dimensional quantum compass model
Erik Eriksson, Henrik Johannesson
We study the one-dimensional (1D) quantum compass model with two independent parameters by means of an exact mapping to the quantum Ising model. This allows us to uncover hidden fe…
The two-impurity Kondo model with spin-orbit interactions
David F. Mross, Henrik Johannesson
We study the two-impurity Kondo model (TIKM) in two dimensions with spin-orbit coupled conduction electrons. In the first part of the paper we analyze how spin-orbit interactions o…
Reduced fidelity in topological quantum phase transitions
Erik Eriksson, Henrik Johannesson
We study the reduced fidelity between local states of lattice systems exhibiting topological order. By exploiting mappings to spin models with classical order, we are able to analy…
