Zero-point quantum swing of magnetic couples
Juba Bouaziz, Julen Ibañez-Azpiroz, Filipe S. M. Guimarães +1
Quantum fluctuations are ubiquitous in physics. Ranging from conventional examples like the harmonic oscillator to intricate theories on the origin of the universe, they alter virt…
Spontaneous and externally driven quantum spin fluctuations of 3d and 4d single atoms adsorbed on graphene
Siham Sadki, Filipe Souza Mendes Guimarães, Juba Bouaziz +3
At the heart of current information nanotechnology lies the search for ideal platforms hosting the smallest possible magnets, i.e. single atoms with magnetic moments pointing out-o…
Directional shift current in mirror-symmetric BCN
J. Ibañez-Azpiroz, I. Souza, F. de Juan
We present a theoretical study of the shift current in a noncentrosymmetric polytype of graphitic BCN. We find that the photoconductivity near the fundamental gap is strongly a…
Ab initio investigation of impurity-induced in-gap states in BiTe and BiSe
Juba Bouaziz, Manuel dos Santos Dias, Julen Ibañez-Azpiroz +1
We investigate in-gap states emerging when a single transition metal impurity is embedded in topological insulators (BiTe and BiSe). We use a combined approach…
Spin-fluctuation and spin-relaxation effects of single adatoms from first principles
Julen Ibañez-Azpiroz, Manuel dos Santos Dias, Stefan Blügel +1
Single adatoms offer an exceptional playground for studying magnetism and its associated dynamics at the atomic scale. Here we review recent results on single adatoms deposited on…
Ab initio calculation of the shift photocurrent by Wannier interpolation
Julen Ibañez-Azpiroz, Stepan S. Tsirkin, Ivo Souza
We describe and implement a first-principles algorithm based on maximally-localized Wannier functions for calculating the shift-current response of piezoelectric crystals in the in…
