Quasiparticles in the Pseudogap Phase of Underdoped Cuprate
Recent angle resolved photoemission [1] and scanning tunneling microscopy [2] measurements on underdoped cuprates have yielded new spectroscopic information on quasiparticles in the pseudogap phase. New features of the normal state such as particle-hole asymmetry, maxima in the energy dispersion and accompanying drops in the spectral weight of quasiparticles agree with the ansatz of Yang et al....
متن کاملUniversality of the electronic structure from a half-filled CuO2 plane
We present angle-resolved photoemission spectroscopy data from insulating A2CuO2X2 (A5Sr, Ca; X 5Cl, Br!, Sr2Cu3O4Cl2, and Bi2Sr2MCu2O8 (M5Er, Dy! single crystals, which illustrate that the low-energy electronic structure of the half-filled cuprates are independent of the apical atom. By performing a photon energy dependent study on Ca2CuO2Cl2, we are able to distinguish between features which ...
متن کاملBCS-like Bogoliubov quasiparticles in high-T(c) superconductors observed by angle-resolved photoemission spectroscopy.
We performed high-resolution angle-resolved photoemission spectroscopy on triple-layered high-T(c) cuprate Bi(2)Sr(2)Ca(2)Cu(3)O(10+delta). We have observed the full energy dispersion (electron and hole branches) of Bogoliubov quasiparticles and determined the coherence factors above and below E(F) as a function of momentum from the spectral intensity as well as from the energy dispersion based...
متن کاملCircular dichroism in angle-resolved photoemission spectra of under- and overdoped Pb-Bi2212.
We use angle-resolved photoemission with circularly polarized excitation to demonstrate that in the 5 x 1 superstructure-free (Pb,Bi)(2)Sr(2)CaCu(2)O(8+delta) (Pb-Bi2212) material there are no signatures of time-reversal symmetry breaking in the sense of the criteria developed earlier [Nature (London) 416, 610 (2002)]]. The dichroic signal retains reflection antisymmetry as a function of temper...
متن کاملPolaronic behavior of undoped high-T(c) cuprate superconductors from angle-resolved photoemission spectra.
We present angle-resolved photoemission spectroscopy (ARPES) data on undoped La2CuO4, indicating polaronic coupling between bosons and charge carriers. Using a shell model, we calculate the electron-phonon coupling and find that it is strong enough to give self-trapped polarons. We develop an efficient method for calculating ARPES spectra in undoped systems. Using the calculated couplings, we f...
