Design of altermagnetism in oxide superlattices exploiting interface effects and quantum confinement
Subhadeep Bandyopadhyay, Rossitza Pentcheva
The discovery of altermagnetism has initiated intensive research and opened new avenues for spin- tronic and transport applications. While current efforts are mostly focused on bul…
Delafossites as an unexpected competing phase to infinite-layer oxides
Armin Sahinovic, Benjamin Geisler, Rossitza Pentcheva
Motivated by the discovery of superconductivity in Sr-doped infinite-layer nickelate films on SrTiO(001), we explore the broader landscape of O oxides through comprehen…
Nanoscale Confinement Enhances Ultrafast Demagnetization
Yoav William Windsor, Tobias Lojewski, Moumita Kundu +21
Nanoscale miniaturization has revolutionized the field of spintronics by enabling exponential growth in areal bit density. A similar leap is also expected in device speeds through…
Engineering the band structure of few-layer graphene by S-doping: from linear dispersion to impurity flat bands
Armin Sahinovic, Rossitza Pentcheva
Motivated by the technological relevance of S-doped few-layer graphene (FLG) in battery applications and in the oxygen reduction reaction, we systematically explore the effect of b…
Disentangling the dynamics of transient spin and orbital magnetization in SrTiO via the inverse Faraday effect from RT-TDDFT
Andri Darmawan, Markus E. Gruner, Rossitza Pentcheva
Motivated by recent evidence of ferroelectricity and even multiferroicity in the prototypical diamagnetic band insulator SrTiO from terahertz experiments, we investigate the ca…
THz carrier dynamics in interface two-dimensional electron gases
Ahana Bhattacharya, Andri Darmawan, Jeong Woo Han +10
A two-dimensional electron gas (2DEG) forms at the interface of complex oxides like (STO) and (LTO), despite each material having a low native conductivity,…
