RESEARCH

My research focuses on dynamical properties (transient and stationary) of open quantum systems out-of-equilibrium.
Fermionic open quantum systems are for example nanosized conductors coupled to source and drain electrodes. The electrodes, play here the role of fermionic heat baths. In this context we study many-body properties of hybrid nanojunctions, molecular systems in STM configuration or complex quantum dots. Focus is on quantum transport set-ups where particle, heat or spin currents arise due to particle or temperature gradients, or in response to external electromagnetic fields.
Bosonic open quantum systems are encountered when (effective) quantum particles interact with a bosonic environment, e.g. with a phonon bath in a crystal or with the quantized modes of an electromagnetic cavity. Systems of interest are for example quantum Brownian particles, driven and  dissipative multilevel systems, or superconducting platforms containing linear and non-linear elements for quantum computation and quantum information purposes.   
In recent years we have developed a many-body theory of quantum transport based on the reduced density matrix approach, which we have applied to investigate transport in carbon nanotube based nanojunctions and molecules. Also, we have used non-perturbative field theory approaches to investigate strongly correlated systems in the Kondo regime and interacting one-dimensional systems. Path integral approaches have recently been used to investigate decoherence and relaxation properties of superconducting qubits interacting with an electromagnetic environment, as well as strongly interacting impurity systems.
