Emergent Surface Kondo Flat Band Driven by Competing Interactions in a Topological Ferromagnet
Nazar Zaremba, Susmita Changdar, Haojie Guo +28
A central goal of modern condensed matter physics is to uncover new quantum states of matter arising from the intertwined effects of strong electron correlations, magnetism, and ba…
Crystallographic imperfections and exotic superconductivity of UBe
Andreas Leithe-Jasper, Markus König, Yusei Shimizu +16
The symmetry of the superconducting gap is related to the symmetry of the crystal structure. In unconventional superconductors, big changes of the critical temperature, critical fi…
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…
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…
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…
