From order to randomness: Onset and evolution of the random-singlet state in bond-disordered BaCu $_{2}$ (Si $_{1 - x}$ Ge $_{x}$ ) $_{2}$ O $_{7}$ spin-chain compounds

T. Shiroka, F. Eggenschwiler, H. -R. Ott +1

Heisenberg-type spin-chain materials have been extensively studied over the years, yet not much is known about their behavior in the presence of disorder. Starting from BaCu $_{2}$ Si$…

Giant spontaneous Hall effect in a nonmagnetic Weyl-Kondo semimetal

Sami Dzsaber, Xinlin Yan, Mathieu Taupin +9

Nontrivial topology in condensed matter systems enriches quantum states of matter, to go beyond either the classification into metals and insulators in terms of conventional band t…

Evidence of Coulomb interaction induced Lifshitz transition and robust hybrid Weyl semimetal in Td MoTe2

N. Xu, Z. W. Wang, A. Magrez +13

Using soft x-ray angle-resolved photoemission spectroscopy we probed the bulk electronic structure of Td MoTe2. We found that on-site Coulomb interaction leads to a Lifshitz transi…
