Superconductivity of bipolarons from quadratic electron-phonon interaction
Zhongjin Zhang, Anatoly Kuklov, Nikolay Prokof'ev +1
In systems with linear electron-phonon interaction (EPI), bound states of polarons, or bipolarons, form by gaining energy from the lattice deformation. The quadratic EPI case is fu…

Soliton States From Quadratic Electron-Phonon Interaction
Zhongjin Zhang, Anatoly Kuklov, Nikolay Prokof'ev +1
We present the first numerically exact study of self-trapped, a.k.a. soliton, states of electrons that form in materials with strong quadratic coupling to the phonon coordinates. P…
