A 2-year postdoctoral appointment is offered to work in the groups led by Roman Orus and Fernando de Juan at DIPC, in Donostia - San Sebastian, Spain. We are looking for a candidate interested in the physics of strongly correlated electron systems and unconventional superconductivity, in the modeling of such systems with numerical techniques, and in particular with tensor network methods. We aim to describe the low-temperature ground states of a variety of systems such as twisted bilayer graphene or doped topological insulators, and our interest is to work towards fermionic finite-temperature tensor network simulations in two and three dimensions.
