Universal thermal breakdown of polaron coherence in one, two, and three dimensions
Jeet Shannigrahi, Janez Bonča, Mona Berciu
How a polaron loses its quasiparticle coherence with increasing temperature is a long-standing open problem. Holstein addressed it in 1959 only in the extreme antiadiabatic, strong…
Hallmark Signatures of Electronic Pairing in Two-Photon Two-Electron Coincidence Angle-Resolved Photoemission Spectroscopy
Janez Bonca, Alberto Nocera, Andrea Damascelli +1
Understanding strongly correlated quantum materials remains a central challenge in condensed matter physics and materials science. While angle-resolved photoemission spectroscopy (…
Fingerprints of preformed pairs in two-electron angle-resolved photoemission spectroscopy
Janez Bonča, Andrea Damascelli, Mona Berciu
We use variational exact diagonalization (VED) to calculate the two-electron removal spectral weight for the Hubbard-Holstein model, starting from the ground-state with two electro…
