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…
Anisotropy of the chiral, semiconducting phase LaRhC: a handedness resolved study
Volodymyr Levytskyi, Ulrich Burkhardt, Markus König +4
Chirality in quantum materials is a topic of significant importance due to its profound effects on the electronic, magnetic, and optical properties of these systems. However, it is…
Unusual magnetic order in EuHg
Rachel Nixon, Nazar Zaremba, Samuel A. Adegboyega +11
In solid-state compounds, the valence of europium can sometimes be mixed -- which is especially favored in structures with several positions for the europium atoms. In this work, w…
Intermediate-valence behavior in U2Rh2Sb
D. Legut, M. Krnel, P. Koželj +9
Intermediate-valence behavior is sometimes observed in lanthanide-based materials containing Ce, Yb, Sm or Eu. However, the number of actinide-based systems that exhibit this type…
Emergent heavy-fermion physics in a new family of topological insulators RAsS (R = Y, La, and Sm)
Iñigo Robredo, Yuan Fang, Lei Chen +10
Realizing topological phases in strongly correlated materials has become a major impetus in condensed matter physics. Although many compounds are now classified as topological insu…
Influence of pressure on properties of multi-gap type-I superconductor BeAu
Rustem Khasanov, Riccardo Vocaturo, Oleg Janson +7
We report on studies of the superconducting and normal state properties of the noncentrosymmetric superconductor BeAu under hydrostatic pressure conditions. The room-temperature eq…
