Phonon dynamics in Chromium under pressure: absence of phonon criticality at the approach of the quantum critical point
P. Rodière, P. Rodière, J. E. Lorenzo +3
Fermi surface nesting is key to understanding the origin of the itinerant antiferromagnetic spin density wave in chromium. This magnetic order is accompanied by a charge-density wa…

Tracing the horizon of tetragonal-to-monoclinic distortion in pressurized trilayer nickelate La4Ni3O10
Sitaram Ramakrishnan, Yingzheng Gao, Valerio Olevano +18
The study investigates pressure‑ and temperature‑induced structural transitions in the trilayer nickelate La4Ni3O10, revealing a direct tetragonal‑to‑monoclinic transition, associa…
