I am interested in quantum many-particle systems. In particular: - Strongly correlated systems
- Entanglement (quantum non-locality)
- Integrable models
- Nonequilibrium phenomena
- Density-matrix renormalization-group (DMRG)
- Algorithms employing tensor network states (TNS>(FCS=TPA=PEPS≥MPS)+(MERA>TTN))
- Stochastic dynamics in networks
