Antiferroquadrupolar Order in Altermagnetic CoF
Daniel Halliday, Laura Pöysti, Chung Xu +5
Altermagnets host non-relativistic spin-split electronic states whose microscopic origin is theoretically linked to a hidden charge order, yet experimental studies of this charge o…
A resonant valence bond spin liquid in the dilute limit of doped frustrated Mott insulators
Cecilie Glittum, Antonio Å trkalj, Dharmalingam Prabhakaran +3
Ideas about resonant valence bond liquids and spin-charge separation have led to key concepts in physics such as quantum spin liquids, emergent gauge symmetries, topological order,…
Ultrafast surface melting of orbital order in La0.5Sr1.5MnO4
Maurizio Monti, Khalid M. Siddiqui, Daniel Perez-Salinas +12
Understanding how light modifies long-range order in quantum materials is key to improving our ability to control functionality. However, this is challenging if the response is het…
Elastic softness of low-symmetry frustrated TiO ( = Co, Fe)
Tadataka Watanabe, Kazuya Takayanagi, Ray Nishimura +4
Orthorhombic pseudobrookites CoTiO and FeTiO have a low-symmetry crystal structure comprising magnetic Co/Fe ions and nonmagnetic Ti ions, wher…
Goldstone mode of the broken helix in U(1) magnet EuIn2As2
Alex Liebman-Pelaez, Samuel J. Garratt, Veronika Sunko +5
Goldstone modes acquire a frequency gap in the presence of perturbations that break the underlying continuous symmetry. Here, we study the response of a spin-based Goldstone mode t…
