Floquet-Universal Hamiltonian Simulation
The work develops a theory for Floquet simulation, where time-periodic Hamiltonians synthesize target time-independent Hamiltonians. It provides a complete characterization of Floquet-universal Hamiltonians that can produce any target Hamiltonian. This construction uses only simple, O(1) local interaction strengths and ratios, making it efficient for simulating many physical systems like lattice models.
