Abstract
Through variational Monte Carlo calculations on Gutzwiller projected wavefunctions, we study the quasiparticle weight for adding and removing an electron from a high-temperature superconductor. We find that the quasiparticle weight is particle-hole symmetric at sufficiently low energy. We propose to use the tunnelling asymmetry as a tool to study the mechanism of electron incoherence in high-temperature superconductors.
