Title: Competing soft phonon modes at the charge-density-wave transitions in $DyT e_{3}$

Abstract

The family of rare-earth tritellurides RTe₃ features charge-density-wave (CDW) order related to strongly momentum-dependent electron-phonon coupling. Similar to other CDW compounds, superconductivity is observed when the CDW order is suppressed via hydrostatic pressure [1]. What sets the heavier members of the RTe₃ series apart is the observation of a second CDW transition at lower temperatures having an in-plane ordering wavevector q_CDW,2 || [100] of almost the same magnitude but orthogonal to the ordering wavevector q_CDW,1 || [001] observed at higher temperatures [2]. Here, we report an inelastic x-ray scattering investigation of the lattice dynamics of DyTe₃. In particular, we show that there are several phonon modes along both in-plane directions, which respond to the onset of the CDW transition at T_CDW,1 = 308 K. Surprisingly, these soft modes close to q_CDW,2 = (0.68, 0, 0) show strong softening near T_CDW,1 but do not exhibit any response to the lower-temperature transition at T_CDW,2 = 68 K. Furthermore our results indicate that the low-temperature CDW order is not just the 90° rotated analogue of the one appearing at high temperatures.

Evidence for Realignment of the Charge Density Wave State in ${ErTe}_{3}$ and ${TmTe}_{3}$ under Uniaxial Stress via Elastocaloric and Elastoresistivity Measurements

Journal Article Straquadine, J. A. W. ; Ikeda, M. S. ; Fisher, I. R. - Physical Review. X

We report the evolution of the charge density wave (CDW) states in the quasi-2D rare-earth tritellurides (RTe₃ for R = Er, Tm) under the influence of in-plane uniaxial stress. Measurements of the elastocaloric effect, resistivity, and elastoresistivity allow us to demonstrate the importance of in-plane antisymmetric strain on the CDW and to establish a phase diagram. We show that modest tensile stress parallel to the in-plane a-axis can reversibly switch the direction of the ordering wavevector between the two in-plane directions, and present a free energy expansion which reproduces the general structure of the observed phenomena.

Multiple charge density wave states at the surface of $TbT e_{3}$

Journal Article Fu, Ling ; Kraft, Aaron M. ; Sharma, Bishnu ; ... - Physical Review B

We studied TbTe₃ using scanning tunneling microscopy (STM) in the temperature range of 298–355 K. Our measurements detect a unidirectional charge density wave (CDW) state in the surface Te layer with a wave vector consistent with that of the bulk q_CDW = 0.30 ± 0.01c*. However, unlike previous STM measurements, and differing from measurements probing the bulk, we detect two perpendicular orientations for the unidirectional CDW with no directional preference for the in-plane crystal axes (a or c axis) and no noticeable difference in wave vector magnitude. In addition, we find regions in which the bidirectional CDW states coexist. Wemore »« less

Unusual Dynamic Charge Correlations in Simple-Tetragonal ${HgBa}_{2} {CuO}_{4 + δ}$

Journal Article Yu, B. ; Tabis, W. ; Bialo, I. ; ... - Physical Review. X

The charge-density-wave (CDW) instability in the underdoped, pseudogap part of the cuprate phase diagram has been a major recent research focus, yet measurements of dynamic, energy-resolved charge correlations are still in their infancy. Such information is crucial in order to help discern the connection between CDW and pseudogap phenomena, and to understand the extent to which charge correlations in general shape the phase diagram. We report a resonant inelastic x-ray scattering study of the underdoped cuprate superconductor HgBa₂CuO_4+δ (T_c = 70 K). At 250 K, above the previously established temperature T_CDW ≈ 200 K that signifies the onset of quasistaticmore »« less

Superconducting energy gap of $2 H - NbS e_{2}$ in phonon spectroscopy

Journal Article Weber, F. ; Rosenkranz, S. ; Heid, R. ; ... - Physical Review B

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 2H–NbSe₂. Measurements were done close to the CDW ordering wave vector qCDW at q=q_CDW + (0,0,l), 0.15 ≤ l ≤ 0.5, for T = 10K (CDW order) and 3.8K (CDW order+superconductivity). We observe changes of the phonon line shape that are characteristic for systems with strong electron-phonon coupling in the presence of a superconducting energy gap 2Δ_c and from which we can demonstrate an l dependence of the superconducting gap. Reversely, our data imply that the CDW energymore »« less

Superconductivity and hybrid soft modes in $Ti {Se}_{2}$

Journal Article Maschek, M. ; Rosenkranz, S. ; Hott, R. ; ... - Physical Review B

The interplay between superconductivity and charge-density-wave (CDW) order plays a central role in the layered transition-metal dichalcogenides. 1T-TiSe₂ forms a prime example, featuring superconducting domes on intercalation as well as under applied pressure. Here, we present high energy-resolution inelastic x-ray scattering measurements of the CDW soft phonon mode in intercalated Cu_xTiSe₂ and pressurized 1T-TiSe₂ along with detailed ab-initio calculations for the lattice dynamical properties and phonon-mediated superconductivity. We find that the intercalation-induced superconductivity can be explained by a solely phonon-mediated pairing mechanism, while this is not possible for the superconducting phase under pressure. We argue that a hybridization of phononmore »« less
