Quantum materials are central to the challenge of harnessing quantum mechanical behavior at macroscopic scales. Strong electronic interactions drive the formation of many-body ground states and the emergence of extraordinary phenomena such as high-temperature superconductivity and quantum magnetism. Using ultrafast laser pulses —both non-resonantly and resonantly tuned to specific phonons— we reshape many-body interactions and engineer the underlying many-body Hamiltonian to generate light-matter hybrid states with no equilibrium analogs. Our work aims to create coherent driven quantum states, including photoinduced quantum spin liquids, superconductivity, and metastable states through the engineered manipulation of the electronic Hamiltonian. These phenomena are investigated across a broad spectrum of strongly correlated systems ranging from complex oxides to organic molecular solids.
