Spectral function of a bipolaron coupled to dispersive optical phonons
K. Kovač, J. Bonča
Using an efficient variational exact diagonalization method, we computed the electron removal spectral function within the framework of the Holstein-Hubbard model containing two el…
Signature of preformed pairs in angle-resolved photoemission spectroscopy
Klemen Kovač, Alberto Nocera, Andrea Damascelli +2
We use density matrix renormalization group (DMRG) and variational exact diagonalization (VED) to calculate the single-electron removal spectral weight for the Hubbard-Holstein mod…
Light bipolarons in a system of electrons coupled to dispersive optical phonons
K. Kovač, J. Bonča
We investigate the ground state properties of the bipolaron coupled to quantum dispersive optical phonons in the one-dimensional Holstein-Hubbard model. We concentrate on the inter…
Optical manipulation of bipolarons in a system with nonlinear electron-phonon coupling
K. Kovač, D. Golež, M. Mierzejewski +1
We investigate full quantum mechanical evolution of two electrons nonlinearly coupled to quantum phonons and simulate the dynamical response of the system subject to a short spatia…
