Title: Low-energy phonons in ${Bi}_{2} {Sr}_{2} {CaCu}_{2} O_{8 + δ}$ and their possible interaction with electrons measured by inelastic neutron scattering

Abstract

Electron-phonon interaction in copper oxide superconductors is still enigmatic. Strong coupling for certain optic phonons is now well established experimentally, but theoretical understanding is challenging. Scattering of electrons near the Fermi surface by the longitudinal acoustic (LA) phonons is expected from basic theory because these phonons modulate electron density. We used inelastic neutron scattering on a large single crystal sample of optimally-doped Bi ₂Sr ₂CaCu ₂O _8+δ to show that low-energy LA phonons could couple to electronic density fluctuations only at small phonon wavevectors, which naturally limits any interaction to forward scattering. Such scattering should not be pairbreaking in the case of the d-wave gap. We also found that previously reported low energy phonon spectral weight half-way to the zone boundary is consistent with conventional lattice dynamics and does not reflect incipient charge density wave (CDW).

Persistent low-energy phonon broadening near the charge-order $q$ vector in the bilayer cuprate ${Bi}_{2} {Sr}_{2} {CaCu}_{2} O_{8 + δ}$

Journal Article He, Y. ; Wu, S. ; Song, Y. ; ... - Physical Review B

Here, we report a persistent low-energy phonon broadening around q _B ~ 0.28 reciprocal lattice unit (r.l.u.) along the Cu-O bond direction in the high- T _c cuprate Bi ₂Sr ₂CaCu ₂O _8+δ(Bi-2212). We show that such broadening exists both inside and outside the conventional charge-density wave (CDW) phase, via temperature-dependent measurements in both underdoped and heavily overdoped samples. Combining inelastic hard x-ray scattering, diffuse scattering, angle-resolved photoemission spectroscopy, and resonant soft x-ray scattering at the Cu L ₃ -edge, we exclude the presence of a CDW in the heavily overdoped Bi-2212 similar to that observed in the underdopedmore »« less

Quasi-two-dimensional fluctuations in the magnetization of $L a_{1.9} C a_{1.1} C u_{2} O_{6 + δ}$ superconductors

We report the results of magnetization measurements with the magnetic field applied along the c axis on superconducting La _1.9Ca _1.1Cu ₂O _6+δ single crystals processed under ultrahigh oxygen pressure. Strong fluctuation effects were found in both low- and high-field regimes. Scaling analysis of the high-field magnetization data near the critical temperature (T _c = 53.5K) region reveals the characteristics of critical fluctuation behavior of quasi-two-dimensional (2D) superconductivity, described by Ginzburg-Landau theory using the lowest Landau level approximation. Low-field magnetic susceptibility data can be successfully explained by the Lawrence-Doniach model for a quasi-2D superconductor, from which we obtained the amore »« less

Magnetic excitations and phonons simultaneously studied by resonant inelastic x-ray scattering in optimally doped ${Bi}_{1.5} {Pb}_{0.55} {Sr}_{1.6} {La}_{0.4} {CuO}_{6 + δ}$

Journal Article Peng, Y. Y. ; Hashimoto, M. ; Sala, M. Moretti ; ... - Physical Review. B, Condensed Matter and Materials Physics

In this paper, magnetic excitations in the optimally doped high-T _c superconductor Bi _1.5Pb _0.55Sr _1.6La _0.4CuO _6+δ (OP-Bi2201, T _c ≃ 34 K) are investigated by Cu L ₃ edge resonant inelastic x-ray scattering (RIXS), below and above the pseudogap opening temperature. At both temperatures the broad spectral distribution disperses along the (1,0) direction up to ~350 meV at zone boundary, similar to other hole-doped cuprates. However, above ~0.22 reciprocal lattice units, we observe a concurrent intensity decrease for magnetic excitations and quasielastic signals with weak temperature dependence. This anomaly seems to indicate a coupling between magnetic, lattice, andmore »« less

Lattice thermal transport in $L a_{3} C u_{3} X_{4}$ compounds $(X = P, As, Sb, Bi)$ : Interplay of anharmonicity and scattering phase space

Journal Article None, None - Physical Review B

Thermal conductivities of La ₃Cu ₃X ₄(X=P,As,Sb,Bi) compounds are examined using first-principles density functional theory and Boltzmann transport methods. We observe a trend of increasing lattice thermal conductivity (κl) with increasing atomic mass, challenging our expectations, as lighter mass systems typically have larger sound speeds and weaker intrinsic scattering. In particular, we find that La ₃Cu ₃P ₄ has the lowest κ _l, despite having larger sound speed and the most restricted available phase space for phonon-phonon scattering, an important criterion for estimating and comparing κ _l among like systems. The origin of this unusual behavior lies in the strengthmore »« less
