Soft and chiral phonons in chiral phase of K3NiO2
Hong Dang Nguyen, Fedir Borodavka, Miroslav Lebeda +6
Raman scattering measurements confirmed the theoretical prediction that the structural phase transition from the achiral tetragonal to the chiral tetragonal phase, which occurs nea…

k-Means Clustering in Fingerprint-Based Configuration Selection for Fitting Interatomic Potentials
Miroslav Lebeda, Jan Drahokoupil, Ludvík Löbel +1
In this study, we present a method for selecting an arbitrary number of distinct configurations from a larger data set by applying k-means clustering to atomistic configuration fin…

Field-induced spin-flip and spin-flop transitions in NdFeO3
Mariana M. Gomes, Rui Vilarinho, E. Miranda +14
Magnetic control of correlated spin systems is central to the development of next-generation spin-based technologies. Rare-earth orthoferrites provide an interesting platform in wh…
