Research subjects
I pursue fundamental research in the field of theoretical condensed matter physics. I am interested in statistical physics and correlated electron problems, and more particularly in the quantum Hall effect, low-dimensional antiferromagnetic systems, topological phases, quantum entanglement and the non-equilibrium dynamics of these systems. I am also developing tools for simulating noisy quantum devices using matrix product states and matrix product operators (MPOs).
Open-source MPO-based simulator for interacting qubits in the presence of decoherence (open systems and Lindblad dynamics): github.com/qiskit-community/lindbladmpo
I participate in research projects EPiQ and BACQ.
