The author has studied momentum distribution of spectral weight around the Fermi level of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sup 8+{delta}} (Bi2212) superconductor by angle resolved photoemission to understand implication of the lattice and spin fluctuations on the excitation spectrum of cuprate superconductors. The photointensity reveals shadow bands at (0.5{pi},0.5{pi}) and equivalent locations, related to the spin density wave (SDW) and suppression of spectral weight around ({pi},0) and equivalent locations, related to an anharmonic and incommensurate charge density wave (ICDW) in the diagonal direction. The work further uncovers the fact that the high {Tc} appears in a complex phase of coexisting lattice and spin fluctuations.
