Abstract

A recent polarized x-ray absorption experiment on the high-temperature cuprate superconductor Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x} indicates the presence of broken parity symmetry below the temperature T*, where a pseudogap appears in photoemission. We critically analyze the x-ray data and conclude that a parity-breaking signal of the kind suggested is unlikely based on the crystal structures reported in the literature. Possible other origins of the observed dichroism signal are discussed. We propose x-ray scattering experiments that can be done in order to determine whether such alternative interpretations are valid or not.

Angle-resolved photoemission spectroscopy (ARPES) studies of cuprate superconductors

Thesis/Dissertation Palczewski, Ari

This dissertation is comprised of three different angle-resolved photoemission spectroscopy (ARPES) studies on cuprate superconductors. The first study compares the band structure from two different single layer cuprates Tl₂Ba₂CuO_6+δ (Tl2201) T_c,max ~95 K and (Bi_1.35Pb_0.85)(Sr_1.47La_0.38)CuO_6+δ (Bi2201) T_c,max 35 K. The aim of the study was to provide some insight into the reasons why single layer cuprate's maximum transition temperatures are so different. The study found two major di erences in the band structure. First, the Fermi surface segments close to ( π,0) are more parallel in Tl2201 than in Bi2201. Second, the shadow band usually related to crystal structure ismore »« less

Temperature Evolution of Energy Gap and Band Structure in the Superconducting and Pseudogap States of Bi₂Sr₂CaCu₂O_8+δ Superconductor Revealed by Laser-Based Angle-Resolved Photoemission Spectroscopy

Journal Article Sun, Xuan; Zhang, Wen-Tao; Zhao, Lin; ... - Chinese Physics Letters

For this study, we carry out detailed momentum-dependent and temperature-dependent measurements on Bi₂Sr₂CaCu₂O_8+δ (Bi2212) superconductor in the superconducting and pseudogap states by super-high resolution laser-based angle-resolved photoemission spectroscopy. The precise determination of the superconducting gap for the nearly optimally doped Bi2212 (T_c=91 K) at low temperature indicates that the momentum-dependence of the superconducting gap deviates from the standard d-wave form (cos(2Φ)). It can be alternatively fitted by including a high-order term (cos(6Φ)) in which the next nearest-neighbor interaction is considered. We find that the band structure near the antinodal region smoothly evolves across the pseudogap temperature without a signature ofmore »« less

Direct Spectroscopic Evidence for Phase Competition between the Pseudogap and Superconductivity in Bi₂Sr₂CaCu₂O_8+δ

Journal Article Hashimoto, Makoto; Nowadnick, Elizabeth; He, Rui-Hua; ... - Nature Materials

In the high-temperature (T_c) cuprate superconductors, increasing evidence suggests that the pseudogap, existing below the pseudogap temperature T*, has a distinct broken electronic symmetry from that of superconductivity. Particularly, recent scattering experiments on the underdoped cuprates have suggested that a charge ordering competes with superconductivity. However, no direct link of this physics and the important low-energy excitations has been identified. We report an antagonistic singularity at Tc in the spectral weight of Bi₂Sr₂CaCu₂O_8+δ as a compelling evidence for phase competition, which persists up to a high hole concentration p ~ 0.22. Comparison with a theoretical calculation confirms that the singularitymore »« less

Local Noncentrosymmetric Structure of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+y} by X-ray Magnetic Circular Dichroism at Cu K-Edge XANES

Journal Article Ivanov, Valentin; Menushenkov, Alexey; Wilhelm, Fabrice; ... - Journal of Superconductivity and Novel Magnetism

The two-dimensional Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+y} (Bi2212), the most studied prototype cuprate superconductor, is a lamellar system made of a stack of two-dimensional corrugated CuO{sub 2} bilayers separated by Bi{sub 2}O{sub 2+y}Sr{sub 2} O{sub 2} layers. While the large majority of theories, proposed to interpret unconventional high T{sub c} superconductivity in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+y}, assume a centrosymmetric tetragonal CuO{sub 2} lattice for the [CuO{sub 2}]Ca[CuO{sub 2}] bilayer, here, we report new compelling results providing evidence for local noncentrosymmetric symmetry at the Cu atom. We have measured polarized Cu K-edge XANES (X-ray absorption near-edge structure) and the K-edgemore »« less
