Unexpected stabilization of a single- charge density wave in pristine 1T-TiSe

Kimoon Higashihira Han, Dongju Hwang, Dongsin Kim +16

Over the past decade, studies revisiting the classical charge-density-wave system 1T-TiSe, long understood to host the triple- order with equivalent subcomponen…

Room-temperature multistage metastability in a moiré superstructure

B. Q. Lv, Yifan Su, Alfred Zong +16

Metastability is fundamental not only to phase ordering and transitions, but also to a broad range of modern technologies, from memory devices to metallic glasses. In condensed-mat…

Long-range magnetic order with disordered spin orientations in a high-entropy antiferromagnet

Yao Shen, Guangkai Zhang, Qinghua Zhang +12

Disorder in magnetic systems typically suppresses long-range order, promoting short-range states such as spin glasses and magnetic clusters. This is particularly prominent in high-…

Competing states in the triangular-lattice - Heisenberg model: a dynamical density-matrix renormalization group study

Shengtao Jiang, Steven R. White, Steven A. Kivelson +1

Previous studies of the triangular-lattice -- Heisenberg antiferromagnet have inferred the existence of a non-magnetic ground-state phase for an intermediate rang…

Observation of correlated plasmons in low-valence nickelates

Y. Shen, W. He, J. Sears +13

The discovery of nickelate superconductors has opened a new arena for studying the behavior of correlated electron liquids that give rise to unconventional superconductivity. While…

Evolution of charge-density-wave soft phonon modes in

Avishek Maity, Stephan Rosenkranz, Raymond Osborn +8

We investigated the lattice dynamics of quasi-two-dimensional Pd-intercalated in relation to its charge-density-wave (CDW) transitions by means of x-ray diffuse a…
