Density matrix of electrons coupled to phonons and the electron-phonon entanglement content of excited states
Gergő Roósz, Karsten Held
We derive the exact reduced density matrix for the electrons in an analytically solvable electron-phonon model. Here, the electrons are described as a Luttinger liquid that is coup…

Entanglement of electrons and the lattice in a Luttinger system
Gergő Roósz, Carsten Timm
The coupling between electronic and lattice degrees of freedom lies at the core of many important properties of solids. Nevertheless, surprisingly little is know about the entangle…

Nonequilibrium dynamics of the Ising chain in a fluctuating transverse field
G. Roósz, R. Juhász, F. Iglói
We study nonequilibrium dynamics of the quantum Ising chain at zero temperature when the transverse field is varied stochastically. In the equivalent fermion representation, the eq…
