Insensitivity of Tc to the residual resistivity in high-Tc cuprates and the tale of two domes

Frontiers in Physics
One of the few undisputed facts about hole-doped high-Tc cuprates is that their superconducting gap Δ has d-wave symmetry. According to ‘dirty’ d-wave BCS theory, even structural (non-magnetic) disorder can suppress Δ, the transition temperature Tc and ...

Unusual metallic conductivity of high-Tc cuprates

Eurasian Journal of Physics and Functional Materials, 2021
The intrinsic mechanisms of the unusual metallic transports of three types of relevant charge carriers (large polarons, excited (dissociated) polaronic components of bosonic Cooper pairs and bosonic Cooper pairs themselves) along the CuO2 layers of high ...

A Method to Probe the Interfaces in La_2−xSr_xCuO₄-LaSrAlO₄-La_2−xSr_xCuO₄ Trilayer Junctions

Condensed Matter, 2023
C-axis trilayer cuprate Josephson junctions are essential for basic science and digital circuit applications of high-temperature superconductors. We present a method for probing the interface perfection in La2−xSrxCuO4 (LSCO)-LaSrAlO4 (LSAO)-La2−xSrxCuO4

Extremely Overdoped Superconducting Cuprates via High Pressure Oxygenation Methods

Condensed Matter, 2021
Within the cuprate constellation, one fixed star has been the superconducting dome in the quantum phase diagram of transition temperature vs. the excess charge on the Cu in the CuO2-planes, p, resulting from O-doping or cation substitution.

Evolution of Charge-Lattice Dynamics across the Kuramoto Synchronization Phase Diagram of Quantum Tunneling Polarons in Cuprate Superconductors

Condensed Matter, 2021
Because of its sensitivity to the instantaneous structure factor, S(Q,t = 0), Extended X-ray Absorption Fine Structure (EXAFS) is a powerful tool for probing the dynamic structure of condensed matter systems in which the charge and lattice dynamics are ...

Superfluid density and two-component conductivity in hole-doped cuprates

Frontiers in Physics, 2022
While the pseudogap dominates the phase diagram of hole-doped cuprates, connecting the antiferromagnetic parent insulator at low doping to the strange metal at higher doping, its origin and relation to superconductivity remains unknown.
