Abstract
In this talk, I will present our study of Floquet topological phase transitions in a one- dimensional dimerized lattice subject to periodic quenches. By alternating between two distinct dimerization configurations within each driving period, the system realizes a time- periodic Hamiltonian that enables Floquet engineering of nontrivial topological phases. We explore how the driving parameters and quench symmetry affect the emergence of zero-energy and π-energy edge states, even when the static Hamiltonians are topologically trivial. The resulting phase diagram reveals rich Floquet-induced behavior, including the coexistence of edge modes with bulk semimetallic spectra and dynamically generated topological states. These findings highlight how periodic driving can be used as a powerful tool to engineer and control topological matter in low-dimensional systems.
