SU(2) approach to the pseudogap phase of high-temperature superconductors: electronic spectral functions
Samuel Bieri, Dmitri Ivanov
We use an SU(2) mean-field theory approach with input from variational wavefunctions of the t-J model to study the electronic spectra in the pseudogap phase of cuprates. In our mod…

Quasiparticle spectral weights of Gutzwiller-projected high T_c superconductors
Samuel Bieri, Dmitri Ivanov
We analyze the electronic Green's functions in the superconducting ground state of the t-J model using Gutzwiller-projected wave functions, and compare them to the conventional BCS…
