Pressure-induced ferromagnetism in the topological semimetal EuCd $_{2}$ As $_{2}$

Elena Gati, Sergey L. Bud'ko, Lin-Lin Wang +10

The antiferromagnet and semimetal EuCd $_{2}$ As $_{2}$ has recently attracted a lot of attention due to a wealth of topological phases arising from the interplay of topology and magnetis…

Reinvestigation of crystal symmetry and fluctuations in La $_{2}$ CuO $_{4}$

A. Sapkota, T. C. Sterling, P. M. Lozano +8

New surprises continue to be revealed about La $_{2}$ CuO $_{4}$ , the parent compound of the original cuprate superconductor. Here we present neutron scattering evidence that the structur…

Electron-phonon coupling and superconductivity in the doped topological-crystalline insulator (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te

A. Sapkota, Y. Li, B. L. Winn +12

We present a neutron scattering study of phonons in single crystals of (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te with $x = 0$ (metallic, but nonsuperconducting) and $x = 0.2$ (nonmetallic…

Signatures of coupling between spin waves and Dirac fermions in YbMnBi $_{2}$

A. Sapkota, L. Classen, M. B. Stone +6

We present inelastic neutron scattering (INS) measurements of magnetic excitations in YbMnBi $_{2}$ , which reveal features consistent with a direct coupling of magnetic excitations to…

Distinct pressure evolution of coupled nematic and magnetic order in FeSe

Anna E. Böhmer, Karunakar Kothapalli, Wageesha T. Jayasekara +13

FeSe, despite being the structurally simplest compound in the family of iron-based superconductors, shows an astoundingly rich interplay of physical phenomena including nematicity…

Collapsed Tetragonal Phase Transition in LaRu $_{2}$ P $_{2}$

Gil Drachuck, Aashish Sapkota, Wageesha Jayasekara +5

The structural properties of LaRu $_{2}$ P $_{2}$ under external pressure have been studied up to 14 GPa, employing high-energy x-ray diffraction in a diamond-anvil pressure cell. At ambi…
