Phonon spectral functions of low-density polaron metals
Luis Walther, Alberto Nocera, Mona Berciu
We use the density matrix renormalization group (DMRG) to compute the phonon spectral function of a one-dimensional spinless Holstein model doped with a low but finite carrier conc…
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 (…
Soliton-antisoliton pairs in the supersymmetric gapped phase of an interacting Majorana chain
Alberto Nocera, Mobin Shakeri, Armin Rahmani +1
A strongly interacting chain of Majorana fermions realizes the supersymmetric tricritical Ising phase, with supersymmetry (SUSY) extending into a symmetry-broken ordered phase adja…
Symmetry-Protected Topological Phases in the Triangular Majorana-Hubbard Ladder
Will Holdhusen, Alberto Nocera, Jian-Xin Zhu +1
We uncover a family of symmetry-protected topological phases in a model of interacting Majorana fermions on triangular-lattice ladders. Included among these phases is one in which…
Enhanced carrier binding and bond correlations in the Hubbard-Su-Schrieffer-Heeger model with dispersive optical phonons
Debshikha Banerjee, Alberto Nocera, Steven Johnston
Electron-phonon (e-ph) interactions play a crucial role in determining many properties of materials. In this context, the Su-Schrieffer-Heeger (SSH) model, where atomic motion modu…
Spectral signatures of residual electron pairing in the extended-Hubbard-Su-Schrieffer-Heeger model
Debshikha Banerjee, Alberto Nocera, George A. Sawatzky +2
We study the electron addition spectrum of the one-dimensional extended Hubbard-Su-Schrieffer-Heeger (HSSH) model in the dilute limit using the density matrix renormalization group…
