Checkerboard-Like Charge Ordering in Underdoped Cuprates
Recent scanning tunneling microscopy measurements which indicate the formation of two-dimensional density modulations at some doping levels in cuprates were reviewed. A model of hard-core bosons which represent bound hole pairs in the two-dimensional doped antiferromagnet was discussed in the context of these experimental results. By means of an exact numerical diagonalization it was shown that...
متن کاملd-Wave Order Parameter in Bi2212 from a Phenomenological Model of High Tc Cuprates
A phenomenological lattice model of high Tc cuprates including order parameter phase fluctuations is considered within the BCS approximation, to interpret the experimental data from ARPES measurements on Bi2212 samples. A KosterlitzThouless (KT) transition temperature T c is estimated below the mean field transition T c , phase boundaries between competing order parameters of different symmetri...
متن کاملComplementary pair-density-wave and d-wave-checkerboard orderings in high-temperature superconductors
The competing orders in the particle-particle P-P channel and the particle-hole P-H channel have been proposed separately to explain the pseudogap physics in cuprates. By solving the Bogoliubov-de Gennes equation self-consistently, we show that there is a general complementary connection between the d-wave-checkerboard DWCB order in the P-H channel and the pair-density-wave PDW order in the P-P...
متن کاملCompetition Between Spin Density Wave Order and Superconductivity in the Underdoped Cuprates
We describe the interplay between d-wave superconductivity and spin density wave (SDW) order in a theory of the hole-doped cuprates at hole densities below optimal doping. The theory assumes local SDW order, and associated electron and hole pocket Fermi surfaces of charge carriers in the normal state. We describe quantum and thermal fluctuations in the orientation of the local SDW order, which ...
متن کاملSuperconducting order parameter symmetry in multilayer cuprates.
In this paper we classify the allowed order parameter symmetries in multilayer cuprates and discuss their physical consequences, with emphasis on Josephson tunneling and impurity scattering. Our solutions to the gap equation are based on highly non-specific forms for the interand intra-plane pairing interactions in order to arrive at the most general conclusions. Within this framework, the bi-l...
