Polaron with Quadratic Electron-phonon Interaction
Stefano Ragni, Thomas Hahn, Zhongjin Zhang +9
We present the first numerically exact study of a polaron with quadratic coupling to the oscillator displacement, using two alternative methodological developments. Our results cov…

Stability conditions for a large anharmonic bipolaron
Matthew Houtput, Jacques Tempere
A large polaron is a quasiparticle that consists of a nearly free electron interacting with the phonons of a material, whose lattice parameters are much smaller than the polaron sc…

Optical conductivity of an anharmonic large polaron gas at weak coupling
Matthew Houtput, Jacques Tempere
In a polar solid, electrons or other charge carriers can interact with the phonons of the ionic lattice, leading to the formation of polaron quasiparticles. The optical conductivit…
