Twin-boundary-induced nonrelativistic spin splitting
Kristoffer Eggestad, Marc Vila, Sverre M. Selbach +1
Nonrelativistic spin splitting (NRSS) in compensated magnetic materials is drawing considerable attention due to its potential impact in next-generation spintronic devices. While N…

Domain Walls and Defects in Ferroelectric Inorganic Halide Perovskites CsGeX (X = Cl, Br, I)
Kristoffer Eggestad, Benjamin A. D. Williamson, Sverre M. Selbach
Among all-inorganic halide perovskites, the only known ferroelectrics are the family of CsGeX (X = Cl, Br, I). Here, we study their ferroelectric domain walls (DWs) and common…

Finite-Temperature Ferroelectric Phase Transitions from Machine-Learned Force Fields
Kristoffer Eggestad, Ida C. Skogvoll, Øystein Gullbrekken +2
Simulating finite temperature phase transitions from first-principles is computationally challenging. Recently, molecular dynamics (MD) simulations using machine-learned force fiel…
