Electron-phonon mediated superconductivity in LaNiO nickel oxides
Alvaro Adrian Carrasco Alvarez, Sebastien Petit, Lucia Iglesias +3
Nickel oxide superconductors offer an alternative playground for understanding the formation of Cooper pairs in correlated materials such as the famous cuprates. By studying the La…
Unexpected antagonism between ferroelectricity and Rashba effects in epitaxially strained SrTiO
Julien Varignon
The Rashba parameter is usually assumed to scale linearly with the amplitude of polar displacements by construction of the spin-orbit interaction. On the basis of first-pri…
Charge ordering as the driving mechanism for superconductivity in rare-earth nickel oxides
Álvaro Adrián Carrasco Álvarez, Lucia Iglesias, Sébastien Petit +3
Superconductivity is one of the most intriguing properties of matter described by an attractive interaction that bounds electrons into Cooper pairs. To date, the highest critical t…
Origin of superconductivity in hole doped SrBiO3 bismuth oxide perovskite from parameter-free first-principles simulations
Julien Varignon
The recent discovery nickel oxides superconductors have highlighted the importance of first-principles simulations for understanding the formation of the bound electrons at the cor…
A multiferroic two-dimensional electron gas
Julien Bréhin, Yu Chen, Maria D'Antuono +6
Multiferroics are compounds in which at least two ferroic orders coexist - typically (anti)ferromagnetism and ferroelectricity. While magnetic order can arise in both insulating an…
Structural instabilities of infinite-layer nickelates from first-principles simulations
Álvaro Adrián Carrasco Álvarez, Sébastien Petit, Lucia Iglesias +3
Rare-earth nickelates RNiO adopting an infinite-layer phase show superconductivity once La, Pr or Nd are substituted by a divalent cation. Either in the pristine or doped form,…
