We study the Holstein model of spinless fermions, which at half filling exhibits a quantum phase transition from a metallic Tomonaga-Luttinger liquid phase to an insulating charge-density-wave (CDW) phase at a critical electron-phonon coupling strength. In our work, we focus on the real-time evolution starting from two different types of initial states that are CDW ordered: (i) ideal CDW states with and without additional phonons in the system and (ii) correlated ground states in the CDW phase… 
Charge density wave breakdown in a heterostructure with electron-phonon coupling
Understanding the influence of vibrational degrees of freedom on transport through a heterostructure poses considerable theoretical and numerical challenges. In this work, we use the density-matrix

Inq, a Modern GPU-Accelerated Computational Framework for (Time-Dependent) Density Functional Theory.
Inq is a new implementation of density functional theory and time-dependent DFT written from scratch to work on graphic processing units (GPUs), representing a modular platform for community-driven application development on emerging high-performance computing architectures.
Efficient and flexible approach to simulate low-dimensional quantum lattice models with large local Hilbert spaces
This work introduces a mapping that allows to construct artificial $U(1)$ symmetries for any type of lattice model and reveals an intimate connection between the Schmidt values of the corresponding matrix-product-state representation and the single-site reduced density matrix.

The two-dimensional $t$-$t^{\prime}$ Holstein model
The competition and interplay between charge-density wave and superconductivity have become a central subject for quasi-2D compounds. Some of these materials, such as the transition-metal

Quantum dynamics of the Hubbard-Holstein model in equilibrium and nonequilibrium: application to pump-probe phenomena.
A criterion for observing oscillations in high T(c) compounds: the time span of the pump light pulse τ(pump) has to be shorter than the phonon oscillation period T(ph), similar to the relaxation time of the charge system.
