摘要	We investigate the role of the squeezing interaction in inducing topological Bogoliubov excitations of a bosonic system. We introduce a squeezing transformation which is capable of reducing the corresponding Bogoliubov-de Gennes Hamiltonian to an effective noninteracting one with the spectra and topology unchanged. In the weak interaction limit, we apply perturbation theory to investigate the squeezing-induced topological gap opening on bosonic Bogoliubov excitations and find that the squeezing interaction plays a role equivalent to that of spin-orbit or Zeeman-like coupling in the effective Hamiltonian. We thus apply this formalism to two existing models to provide a deeper understanding of their topological structures. We also construct minimal models based on the elegant Clifford algebra for realizing bosonic topological Bogoliubov excitations. Our construction is potentially applicable to experiments in bosonic systems.
