Theory for the interdependence of high-Tc superconductivity and dynamical spin fluctuations
TL;DR: In this article, the doping and temperature dependence of the quasi particle excitation spectrum of the 2D one band Hubbard model in the normal and superconducting state using the fluctuation exchange approximation was analyzed.

Pairing glue in cuprate superconductors from the self-energy revealed via machine learning
TL;DR: Yamaji et al. as discussed by the authors showed that soft thermal fluctuations give rise to peaks in both components of the self-energy at a frequency comparable to the superconducting gap, all irrespective of the nature of the pairing boson.

A neutron study of magnetic domain correlations in antiferromagnetically coupled multilayers
TL;DR: In this article, a simple domain model relates the observed scattering to the domain correlation length and the magnetic disorder, and highly vertically correlated magnetic domains are observed with in-plane correlation lengths, at remanence, of 1.5 and 7 μm for the Cu and Ru systems, respectively.

Role of fluctuations for density-wave instabilities: Failure of the mean-field description
Mareike Hoyer,Jörg Schmalian +1 more
TL;DR: In this article, Kos et al. analyzed the fluctuation corrections to the equation of state of the density-wave order parameter for commensurate charge-density waves and spin-density wave due to perfect nesting and found that contributions due to longitudinal and transverse fluctuations cancel each other.

Complex critical exponents for percolation transitions in Josephson-Junction arrays, antiferromagnets, and interacting bosons
TL;DR: It is shown that the critical behavior of the XY quantum-rotor model undergoing a percolation transition is dramatically affected by its topological Berry phase 2π ρ, and critical properties not captured by the usual Ginzburg-Landau-Wilson description of phase transitions arise.
