Fermi surface change and $d$-wave superconductivity in the square lattice Kondo-Heisenberg model

Alexander Nikolaenko, Riccardo Rende, Luciano Loris Viteritti +2

We study the two-dimensional Kondo-Heisenberg model on a square lattice, with the conduction electrons away from half-filling, using neural network quantum states. Mapping the grou…
