Electronic correlations driving Chirality-Induced Spin Selectivity
Jacek Herbrych, Maria Daghofer
We explicitly account for electron-electron interactions when modeling low-dimensional helical organic molecules. We show that competition between various hopping channels, togethe…
Electronic excitations in the Shastry-Sutherland compound SrCu(BO)
Tariq Leinen, Ola K. Forslund, Eugenio Paris +13
SrCu2(BO3)2 (SCBO) is a paradigmatic realization of the Shastry-Sutherland model, hosting geometrically frustrated spin dimers and a variety of quantum magnetic phases and phenomen…
Altermagnetic polarons: the fate of alter magnetic band splittings at strong coupling
Maria Daghofer, Krzysztof Wohlfeld, Jeroen van den Brink
While a spin-dependent band splitting is one of the characteristic features of altermagnets, the conventional band picture itself breaks down in the many altermagnets that are corr…
Robustness of the flux-free sector of the Kitaev honeycomb against environment
Alexander Sattler, Maria Daghofer
The Kitaev honeycomb model (KHM) consists of spin- particles on a honeycomb lattice with direction-dependent Ising-like interactions. It can alternatively be described in term…
Robustness of topological edge states in alternating spin chains against environment
Alexander Sattler, Maria Daghofer
Both the Haldane spin- chain and dimerized chains of spin- exhibit topologically protected edge states that are robust against specific perturbations. Recently, such spin c…
Charge and magnetic orders in a two-band model with long-range interactions for infinite-layer nickelates NdNiO
Tharathep Plienbumrung, Jean-Baptiste Morée, Andrzej M. OleŠ+1
We present an effective two-band model for infinite-layer nickelates NdNiO that consisting of a band centered at Ni site and an interstitial -like band centered at Nd si…
