Research expertise

The “Quantum Materials by Design” group at Utrecht University, led by Prof. Zeila Zanolli, is internationally recognized for the development and use of first-principles simulation techniques to predict a wide range of physical properties of Quantum Materials, including spectroscopy, topology, quantum transport, and superconductivity. We address the electronic structure problem of interacting electrons in solids and molecules by solving the Schrödinger equation in the framework of Density Functional Theory (DFT).

Excited states properties (optical absorption, exciton physics) are computed within a many-body perturbation theory (MBPT) formalism (GW approximation, Bethe-Salpeter Equation). The dynamics of excited carriers (including interaction with lattice vibration) and time-dependent optical spectra are predicted using a real-time rate equation approach on top of the GW/BSE approach.

We compute quantum electron transport using Non-Equilibrium Green’s Functions with a DFT (or Tight-Binding) Hamiltonian. We recently implemented a combined DFT-Bogolibov de Gennes formalism in the SIESTA code to model conventional and unconventional superconductivity.

We contribute to the development of the open-source codes YAMBO and SIESTA.

Role in QUONDENSATE

In QUONDENSATE we will predict the structural, electronic and optical properties of Transition Metal Dichalcogenides (TMDs) with defects. We contribute to Work Packages 1 (TMD materials development), 3 (Charecterization of defect networks), 4 (Implementation of Quantum Reservoir Computing with defect networks). We lead WP5 (Exploitation, Dissemination, and Communication).
