Objective Strongly correlated quantum systems, which are at the heart of many open problems in condensed matter,quantum chemistry, or high-energy physics, are challenging to understand due to their intricate entanglementstructure. Quantum information theory provides the right framework to characterize highly entangledstates and has given rise to the class of Tensor Network States, which capture the entanglement structure ofstrongly correlated systems by building the global wavefunction from local tensors and provide an efficientdescription of their low-energy states.In this project, we will develop a framework for the systematic study of strongly correlated systems usingexact wavefunctions based on Tensor Network States. It will give us the tools to construct controlled familiesof states by encoding the relevant structure of the system directly into the wavefunction, rather than aHamiltonian, and to study their behavior. Since the tensor describing the wavefunction also gives rise to anassociated Hamiltonian, this establishes a framework for building solvable models with the tensor as thenew central object.The novelty of our approach lies in the fact that quantum information gives us the tools to systematicallyconstruct wavefunctions for general strongly correlated systems, while at the same time, encoding thestructure of the problem directly into the wavefunction results in small families of states with a directphysical interpretation of the parameters, unlike for fully variational approaches.We will apply our framework to study the physics of a range of strongly correlated models, in particularfrustrated fermionic and spin systems, in order to understand the possible physics they can exhibit. Thiswill enhance our understanding of the physics of strongly correlated systems, and, together with numericalresults, experimental findings, and quantum simulations, ultimately lead to new applications and materialsbased on strongly correlated matter.
