Behaviour of superconductivity energetic characteristics in electron-doped cuprates. A simple model [PDF]

, 2007
A simple model to describe the energetic phase diagram of electron-doped cuprate superconductor is developed. Interband pairing operates between the UHB and the defect states created by doping and supplied by both extincting HB-s.

Field-dependent specific heat of the canonical underdoped cuprate superconductor $$\hbox {YBa}_2\hbox {Cu}_4\hbox {O}_8$$ YBa 2 Cu 4 O 8

Scientific Reports, 2020
The cuprate superconductor $$\hbox {YBa}_2\hbox {Cu}_4\hbox {O}_8$$ YBa 2 Cu 4 O 8 , in comparison with most other cuprates, has a stable stoichiometry, is largely free of defects and may be regarded as the canonical underdoped cuprate, displaying marked

Evidence for a vestigial nematic state in the cuprate pseudogap phase [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance In the cuprate pseudogap phase, an energy gap of unknown mechanism opens, and both an electronic nematic phase (NE) and a density-wave (DW) phase appear.

Beyond DPA: An Atomistic Framework for a Quantitative Description of Radiation Damage in YBa2Cu3O7 [PDF]

Small Sci
To quantify primary radiation damage and describe defect morphology in the high‐temperature superconductor YBa2Cu3O7, an atomistic multiscale framework is proposed. Coupling Molecular Dynamics and Binary Collision Approximation simulations and integrating the atomistic description with Primary Knock‐on Atom spectra from Monte Carlo and transport ...

Electronic Raman response in electron-doped cuprate superconductors

, 2011
The electronic Raman response in the electron-doped cuprate superconductors is studied based on the $t$-$t'$-$J$ model. It is shown that although the domelike shape of the doping dependent peak energy in the $B_{2g}$ symmetry is a common feature for both

Incommensurate Phonon Anomaly and the Nature of Charge Density Waves in Cuprates

Physical Review X, 2018
While charge density wave (CDW) instabilities are ubiquitous to superconducting cuprates, the different ordering wave vectors in various cuprate families have hampered a unified description of the CDW formation mechanism.
