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…
Lattice-charge coupling in a trilayer nickelate with intertwined density wave order
Xun Jia, Yao Shen, Harrison LaBollita +16
Intertwined charge and spin correlations are ubiquitous in a wide range of transition metal oxides and are often perceived as intimately related to unconventional superconductivity…
Soft phonon and the central peak at the cubic-to-tetragonal phase transition in SrTiO
Avishek Maity, Klaus Habicht, Michael Merz +8
The continuous displacive phase transition in SrTiO near K features a central elastic peak in neutron scattering investigations at temperatures above , i…
Charge-density-wave quantum critical point under pressure in 2-TaSe
Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13
Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
Large Kohn anomaly and phonon collapse induced by charge density wave in UPtSi
Jooseop Lee, Greta L. Chappell, Ryan E. Baumbach +2
Using high-energy-resolution inelastic x-ray scattering, we observe anomalous softening and damping of the transverse acoustic phonon in UPtSi as the system is cooled towar…
Origin of chirality in transition-metal dichalcogenides
Kwangrae Kim, Hyun-Woo J. Kim, Seunghyeok Ha +15
Chirality is a ubiquitous phenomenon in which a symmetry between left- and right-handed objects is broken, examples in nature ranging from subatomic particles and molecules to livi…
Precursor phase with full phonon softening above the charge-density-wave phase transition in -TaSe
Xingchen Shen, Rolf Heid, Roland Hott +8
Research on charge-density-wave (CDW) ordered transition-metal dichalcogenides continues to unravel new states of quantum matter correlated to the intertwined lattice and electroni…
Observation of a Chiral Wave Function in Twofold Degenerate Quadruple Weyl System BaPtGe
Haoxiang Li, Tiantian Zhang, A. Said +10
Topological states in quantum materials are defined by non-trivial topological invariants, such as the Chern number, which are properties of their bulk wave functions. A remarkable…
Superconducting energy gap of -NbSe in phonon spectroscopy
F. Weber, S. Rosenkranz, R. Heid +1
We present a high energy-resolution inelastic x-ray scattering data investigation of the charge-density-wave (CDW) soft phonon mode upon entering the superconducting state in -…
Wave vector dependent electron-phonon coupling drives charge-density-wave formation in TbTe3
M. Maschek, S. Rosenkranz, R. Heid +4
We present a high energy-resolution inelastic x-ray scattering investigation of the soft phonon mode in the charge-density-wave system TbTe. We analyze our data based on lattic…
