Evolution of charge-density-wave soft phonon modes in $Pd_{x} ErTe_{3}$

Avishek Maity, Stephan Rosenkranz, Raymond Osborn +8

We investigated the lattice dynamics of quasi-two-dimensional Pd-intercalated $ErTe_{3}$ 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…

Large Kohn anomaly and phonon collapse induced by charge density wave in UPt $_{2}$ Si $_{2}$

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 UPt $_{2}$ Si $_{2}$ as the system is cooled towar…

Soft phonon and the central peak at the cubic-to-tetragonal phase transition in SrTiO $_{3}$

Avishek Maity, Klaus Habicht, Michael Merz +8

The continuous displacive phase transition in SrTiO $_{3}$ near $T_{c} \approx 105$ K features a central elastic peak in neutron scattering investigations at temperatures above $T_{c}$ , i…

Charge-density-wave quantum critical point under pressure in 2 $H$ -TaSe $_{2}$

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…
