Low energy phenomenology of the overdoped cuprates: Viability of the Landau-BCS paradigm

open access: yesPhysical Review Research, 2020
We use dirty d-wave BCS theory to calculate absolute superfluid density, residual specific heat, Volovik effect, and thermal conductivity and compare to experiments on the cuprate superconductor La_{2−x}Sr_{x}CuO_{4}, showing that the theory provides a ...

Monte Carlo study of the pseudogap and superconductivity emerging from quantum magnetic fluctuations

open access: yesNature Communications, 2022
The origin of pseudogap in high-T c superconductors remains a big puzzle. Here, the authors report numerical evidence of pseudogap behavior employing Quantum Monte Carlo algorithm emerging from pairing fluctuations in a quantum-critical non-Fermi liquid,

Charge Order in the Pseudogap Phase of Cuprate Superconductors

open access: yes, 2014
In a multiorbital model of the cuprate high-temperature superconductors soft antiferromagnetic (AF) modes are assumed to reconstruct the Fermi surface to form nodal pockets.

Crossover from two-dimensional to three-dimensional superconducting states in bismuth-based cuprate superconductor [PDF]

open access: yesNature Physics, 2019
To decipher the mechanism of high-temperature superconductivity, it is important to know how the superconducting pairing emerges from the unusual normal states of cuprate superconductors 1 – 4 , including the pseudogap 5 , 6 , strange metal 7 , 8 and ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Lattice Instability in High Temperature Superconducting Cuprates and FeAs Systems: Polarons Probed by EXAFS

open access: yesAdvances in Condensed Matter Physics, 2010
Carrier-induced lattice distortion (signature of polaron) in oxypnictide superconductors is found by an instantaneous local probe, extended X-ray absorption fine structure (EXAFS). Polaron formation is detected as two distinct nearest neighbor distances (

Unraveling the nature of spin excitations disentangled from charge contributions in a doped cuprate superconductor

open access: yesnpj Quantum Materials, 2022
The nature of the spin excitations in superconducting cuprates is a key question toward a unified understanding of the cuprate physics from long-range antiferromagnetism to superconductivity.

High-pressure effects on single crystals electron-doped r$_{2-x}$Ce$_{x}$CuO$_{4}$

open access: yes, 2013
We present high pressure diamond anvil cell synchrotron X-ray, resistivity, and ac-susceptibility measurements on electron-doped cuprate Pr$_{2-x}$Ce$_{x}$CuO$_{4}$ to much higher pressures than previously reported.

Visualization of the periodic modulation of Cooper pairing in a cuprate superconductor [PDF]

open access: yesNature Physics, 2018
In cuprate superconductors, the existence of various intertwined orders associated with spin, charge and Cooper pairs1,2 is an obstacle in understanding the mechanism of Cooper pairing. The ubiquitous charge order is particularly important2–7.
