There is tremendous interest in employing collective excitations of the lattice, spin, charge, and orbitals to tune strongly correlated electronic phenomena. We report such an effect in a ruthenate, Ca_{3}Ru_{2}O_{7}, where two phonons with strong electronphonon coupling modulate the electronic pseudogap as well as mediate charge and spin density wave fluctuations. Combining temperaturedependent Raman spectroscopy with density functional theory reveals two phonons,

Abstract R V_{6}Sn_{6}family of materials (R = Sc, Y, Lu), ScV_{6}Sn_{6}hosts an unusual charge density wave ground state as well as structural similarities with theA V_{3}Sb_{5}system (A = K, Cs, Rb). In this work, we combine Raman scattering spectroscopy with firstprinciples lattice dynamics calculations to reveal phonon mixing processes in the charge density wave state of ScV_{6}Sn_{6}. In the low temperature phase, we find at least four new peaks in the vicinity of the Vcontaining totally symmetric mode near 240 cm^{−1}suggesting that the density wave acts to mix modes ofP 6/m m m and symmetry  a result that we quantify by projecting phonons of the high symmetry state onto those of the lower symmetry structure. We also test the stability of the shortrange ordered density wave state under compression and propose that both physical and chemical pressure quench the effect. We discuss these findings in terms of symmetry and the structureproperty trends that can be unraveled in this system.$$R\bar{3}m$$ $R\overline{3}m$ 
We describe the confining instabilities of a proposed quantum spin liquid underlying the pseudogap metal state of the holedoped cuprates. The spin liquid can be described by a SU(2) gauge theory of
N _{f}= 2 massless Dirac fermions carrying fundamental gauge charges—this is the lowenergy theory of a meanfield state of fermionic spinons moving on the square lattice withπ flux per plaquette in the ℤ_{2}center of SU(2). This theory has an emergent SO(5)_{f}global symmetry and is presumed to confine at low energies to the Néel state. At nonzero doping (or smaller Hubbard repulsionU at halffilling), we argue that confinement occurs via the Higgs condensation of bosonic chargons carrying fundamental SU(2) gauge charges also moving inπ ℤ_{2}flux. At halffilling, the lowenergy theory of the Higgs sector hasN _{b}= 2 relativistic bosons with a possible emergent SO(5)_{b}global symmetry describing rotations between ad wave superconductor, period2 charge stripes, and the timereversal breaking “d density wave” state. We propose a conformal SU(2) gauge theory withN _{f}= 2 fundamental fermions,N _{b}= 2 fundamental bosons, and a SO(5)_{f}×SO(5)_{b}global symmetry, which describes a deconfined quantum critical point between a confining state which breaks SO(5)_{f}and a confining state which breaks SO(5)_{b}. The pattern of symmetry breaking within both SO(5)s is determined by terms likely irrelevant at the critical point, which can be chosen to obtain a transition between Néel order andd wave superconductivity. A similar theory applies at nonzero doping and largeU , with longerrange couplings of the chargons leading to charge order with longer periods. 
Abstract We model the pseudogap state of the hole and electrondoped cuprates as a metal with hole and/or electron pocket Fermi surfaces. In the absence of longrange antiferromagnetism, such Fermi surfaces violate the Luttinger requirement of enclosing the same area as free electrons at the same density. Using the Ancilla theory of such a pseudogap state, we describe the onset of conventional
d wave superconductivity by the condensation of a chargee Higgs boson transforming as a fundamental under the emergent SU(2) gauge symmetry of a backgroundπ flux spin liquid. In all cases, we find that thed wave superconductor has gapless Bogoliubov quasiparticles at 4 nodal points on the Brillouin zone diagonals with significant velocity anisotropy, just as in the BCS state. This includes the case of the electrondoped pseudogap metal with only electron pockets centered at wavevectors (π , 0), (0,π ), and an electronic gap along the zone diagonals. Remarkably, in this case, too, gapless nodal Bogoliubov quasiparticles emerge within the gap at 4 points along the zone diagonals upon the onset of superconductivity. 
null (Ed.)We use polarizationresolved electronic Raman spectroscopy to study quadrupolar charge dynamics in a nonmagnetic F e S e 1 − x S x superconductor. We observe two types of longwavelength X Y symmetry excitations: 1) a lowenergy quasielastic scattering peak (QEP) and 2) a broad electronic continuum with a maximum at 55 meV. Below the tetragonaltoorthorhombic structural transition at T S ( x ) , a pseudogap suppression with temperature dependence reminiscent of the nematic order parameter develops in the X Y symmetry spectra of the electronic excitation continuum. The QEP exhibits critical enhancement upon cooling toward T S ( x ) . The intensity of the QEP grows with increasing sulfur concentration x and maximizes near critical concentration x c r ≈ 0.16 , while the pseudogap size decreases with the suppression of T S ( x ) . We interpret the development of the pseudogap in the quadrupole scattering channel as a manifestation of transition from the nonFermi liquid regime, dominated by strong Pomeranchuklike fluctuations giving rise to intense electronic continuum of excitations in the fourfold symmetric hightemperature phase, to the Fermi liquid regime in the brokensymmetry nematic phase where the quadrupole fluctuations are suppressed.more » « less

We present a valence transition model for electron and holedoped cuprates, within which there occurs a discrete jump in ionicity Cu2+ > Cu1+ in both families upon doping, at or near optimal doping in the conventionally prepared electrondoped compounds and at the pseudogap phase transition in the holedoped materials. In thin films of the T' compounds, the valence transition has occurred already in the undoped state. The phenomenology of the valence transition is closely related to that of the neutraltoionic transition in mixedstack organic chargetransfer solids. Doped cuprates have negative chargetransfer gaps, just as rareearth nickelates and BaBiO3. The unusually high ionization energy of the closed shell Cu1+ ion, taken together with the dopingdriven reduction in threedimensional Madelung energy and gain in twodimensional delocalization energy in the negative charge transfer gap state drives the transition in the cuprates. The combined effects of strong correlations and small dp electron hoppings ensure that the systems behave as effective 1/2filled Cu band with the closed shell electronically inactive O2 ions in the undoped state, and as correlated twodimensional geometrically frustrated 1/4filled oxygen hole band, now with electronically inactive closedshell Cu1+ ions, in the doped state. The model thus gives microscopic justification for the twofluid models suggested by many authors. The theory gives the simplest yet most comprehensive understanding of experiments in the normal states. The robust commensurate antiferromagnetism in the conventional T' crystals, the strong role of oxygen deficiency in driving superconductivity and charge carrier sign corresponding to holes at optimal doping are all manifestations of the same quantum state. In the holedoped pseudogapped state, there occurs a biaxial commensurate period 4 charge density wave state consisting of O1 Cu l(1+)O1 spin singlets that coexists with broken rotational C4 symmetry due to intraunit cell oxygen inequivalence. Finite domains of this broken symmetry state will exhibit twodimensional chirality and the polar Kerr effect. Superconductivity within the model results from a destabilization of the 1/4filled band paired Wigner crystal [Phys. Rev. B 93, 165110 (2016) and ihid. 93, 205111 (2016)]. We posit that a similar valence transition, Ir4+ > Ir3+, occurs upon electron doping Sr2IrO4. We make testable experimental predictions in cuprates including superoxygenated La2CuO4+delta and iridates. Finally, as indirect evidence for the valence bond theory of superconductivity proposed here, we note that there exist an unusually large number of unconventional superconductors that exhibit superconductivity proximate to exotic charge ordered states, whose band fillings are universally 1/4 or 3/4, exactly where the paired Wigner crystal is most stable.more » « less
